Bitcoin Forum

I'm creating a new forum FOR ANYONE to post photos of what they have going on with their mining setup to give others ideas of what may be the best way to start off BY LEARNING FROM OTHERS FAILURES AND SUCCESSES.

So PLEASE FEEL FREE TO POST YOUR IDEAS WITH PHOTO(s) AND DESCRIPTION(S) OF WHAT'S IN THE PHOTO(s).

If you see a question mark (?) in a post for an image, simply refresh your browser and it should display the image the 2nd time.

I've learned a LOT through the years on how to manage heat generated by mining rigs.  I believe I've found an affective way to manage the heat without air conditioning.  

Trying to use air conditioning to battle the heat generated by mining rigs is really a losing battle.  Especially, if you have a lot of rigs.  I've found through the years it is best to find a way to simply get the heat AWAY from the rigs and OUT of the mining room or box.

You can see from my posts made in the following link [From back in 2014 - You'll need to scroll down a bit] that I do have SOME experience with mining in regards to experimenting with different ways of managing the heat. https://bitcointalk.org/index.php?topic=766998.40 (https://bitcointalk.org/index.php?topic=766998.40). For whatever reason, the link I just provided to another forum where I've made posts since 2014 is no longer active.  Sorry...  It's rather disappointing.  I had over 500 posts in that thread with hundreds of photos.

I'm currently in ANOTHER REMODEL in my mining room to make it even larger and manage the heat even better.  Updates to that remodel will be shared at a later date.

I'm currently working on a small mining room for my dad in his garage.  I've FINALLY convinced my dad how valuable crypto currency is to the FREEDOM of mankind and how it's the next big thing that will be BIGGER than the internet.  He recently showed interest in mining.  So, I decided to give him some of my old hardware that will still be profitable to mine with for him to make some extra money during his retirement.  Especially, since I believe social security will not be around much longer for he and my mother to live off of.

Here are images with comments of the current progress with the small mining room in my dad's garage from start to current.  [Be patient while I continue posting these one after another with comments.  This will take a little while]:  

A 2" x 8" was notched out to straddle the Main Distribution Panel (MDP) and placed to line up perfectly with the 2" x 4" mounted on the rack.  This END will be covered with plywood.
We also made sure the door panel for the MDP is not inhibited from access in the event of an emergency.  NEC requires easy access in the event of an emergency.  They would simply walk into the mining room, open the MDP door to flip breakers as needed from the inside.  This is a 200 Amp MDP.

We have everything perfectly leveled.  We have the feet sitting on shims we made to level it to make sure the walls will be perfectly vertical; especially for the door we install on the other end of the mining room.  This corner will have plywood covering the sides of each rack. 

L-Brackets will be used on the inside to pull the 2" x 4"s together to avoid gaps and to keep perfectly vertical/level.

https://i.imgur.com/1vCYXMW.jpg

You see the 5th orange 10'2 wire poking out through the ceiling.  That's the old heater circuit that will be rerouted for the 5th 220V/30A circuit to use for mining.

This is the 77" W x 72" H x 24" D rack with four (4) shelves.  A 5th shelf will be added on top of the 48" and 77" racks in the future for the 5th 220V/30A circuit.  A frame for 15 x 20 inch box fans will be made for this particular rack.

I have a 30" TPI Corporation 7800 CFM fan [Exactly like the ones I already have in my mining room] ready for install in the ceiling to exhaust the heat out of the mining room into the attic.  We have an idea for another 30 inch TPI Corporation 7800 CFM fan to be mounted for intake to offset static pressure.

Dad is excited to get this mining room build going.  He's also enjoying the workout.  He will be 75 the month of April.  We are constructing a wall with a 30 inch wide door on this side you see here.  The wall will be made with door roughed out on the floor on the other side of the garage then the bottom will be glued with Liquid Nails to the concrete and the top connected to ceiling joists above the garage.

The rack straight across is 48" W x 72" H x 18" D
The rack my dad is connecting a 2"x 4" to is 77" W x 72" H x 24" D.

We have 5 x 220V/30A circuits and 3 x 110V/20A circuits roughed in for the new added electrical.  You may only see 4 orange 10/2 wiring coming from beneath the Main Distribution Panel.  The 5th one is currently in the ceiling.  It once fed a heater that was mounted to the ceiling.  We took the heater down but we still need to reroute that circuit to the future Power Distribution Units (PDU's).

You can see some shims on the floor underneath the rack at the far end.  Actually, the shims come all the way under the feet of the racks to where my dad is standing.  We have the end where my dad is standing seemed up 0.75".  His garage concrete slab has a long decline in elevation from the back of the garage towards the garage door.  It was important to have it level for the door we will install on this end of the mining room.

Another look at how the wall on the other side of the rough door opening was braced to the existing wall.

https://i.imgur.com/vSMT2vQ.jpg

The 2"x4" pieces on the floor have been glued with liquid nails to have something to nail the plywood into at the base.  Same goes for the other side.  However, the other side was also braced to the wall just in case the glue comes loose over time.

Seven (7) Bitmain S-7's and one (1) Bitmain S-5 are covered up with that sheet to keep dust off.  All of those will fit on one shelf.  The other shelves are intended for GPU mining rigs.

We need to install the 30" diameter 7,800 CFM exhaust fan in the ceiling.  That's next on the agenda.

One fan sitting in a frame to allow you to see how it's framed out well to keep heat from coming around the top, sides or bottom to recirculate out the back and into the rigs like a convection oven.  We don't want that.  Hence, making sure it's sealed completely around each fan to avoid a convection oven affect.

https://i.imgur.com/Nv7JqKy.jpg

It's coming along great!!!  He's excited about it.

A few trim pieces yet to be installed to seal in corners, etc...

I'm going to take a break for a while and come back with some more updates.

Cheers...

Please keep posting, Great build and pics.

For cooling just basically have a fan and open windows. When summer hits have a portable room a/c - swamp cooler unit I'll set up. Thank God for solar.

Any other ideas are appreciated.

Sure...  I'll keep posting...

No further updates as of yet.

I'm in the process of remodeling my mining room at my house.  However, I'm focussing on helping my dad with his NEW mining room first before getting back to mine.

Here are some Imgurs from past and present with mine.  However, IT WILL LOOK TOTALLY DIFFERENT FROM WHAT YOU SEE IN THE FOLLOWING PHOTOS WHEN I"M DONE.  What you see in my Dad's garage is small compared to what I'm doing in my home.

Really nice timeline, looks like a great mini data center! 

Was that panel put in specifically for mining, or are you guys tapping off existing circuits?  Just wondering

Hi Electon Rancher,

Apologies for the delay.  I've been sleeping.  I was exhausted after going a couple of days with only 3.5 to 4.5 hours of sleep each day.

Thanks for the comment!

The electrical panel is for the entire home.  However, five (5) 220V/30A breakers were installed for five (5) 220V/30A PDU's (Power Distribution Units).  So, those five (5) 30 Amp circuits are strictly for the mining room.

We also have three (3) 110V/20A circuits for the mining room fans and a couple of lights.

The S7's will take up 1.5 220V/30A PDU's.  Which will leave 3.5 220V/30A PDU's for GPU mining.

This gives you an example of the size of each rig for GPU mining:  https://imgur.com/a/PDU13 (https://imgur.com/a/PDU13). Three (3) of those size rigs will be on each shelf of the 77" Wide racks.  Two (2) of those will go on each shelf for the 48" Wide rack.

NOTE:  MORE PHOTOS WILL BE POSTED NEXT WEEKEND...

Electrical has been completed in the mining room.  Here's a photo of a 120V/20A outlet for 20 inch box fans behind the 77 inch wide rack:

FIRST OFF - THIS PARTICULAR POST IS NOT MY DAD'S PLACE...  THIS IS MY PLACE:

I've learned from mistakes I made since 2014; which has led to my fourth mining room build [My dad's is the 5th and current one on-going at my place is the 4th].  My dad's will be done right THE FIRST TIME.  While mine involves taking stuff down to put new stuff up.

PLEASE ignore the LACK of wire management at the moment.  I've used power cords connected together to make long extension cords to reach to existing PDU's (Power Distribution Units) from the new racks outside the old wooden mining closet [Which was Build Number 3].  I've also added 16 port switches for internet at each rack but still need to do wire management with the Cat6 cables.  Everything was originally fed by a TP-Link 48 port switch.

Here is the current mess in the process of remodel.  These are two racks outside the old mining closet.  The rack straight ahead already has a Fan Frame attached behind it with 12 x 20 inch box fans like you have seen constructed at my dad's place.  The rack on the right has yet to have the exact same thing done to it.  There will be another rack just like these (77" W x 72" H x 24" D) with a Fan Frame behind it as well.  Then a 48" W x 72" H x 18" D rack on the other end and a door for entrance.

The rack on the right will be pulled back towards you to even up the corners and connect them together.

https://i.imgur.com/6ppTz8p.jpg

WE ARE STILL AT MY PLACE - NOT MY DAD'S PLACE:

Here's a look at the right side of the OLD wooden mining closet.  There was once a 77" W x 72" H x 24" D rack with 5 shelves full of GPU mining rigs.  3 shelves have been emptied and taken down.  The 4th shelf has one rig on it and the bottom shelf has 2 rigs on it.  I'll have it completely taken apart tomorrow and another 48" wide rack to transfer rigs to while dismantling the 77" wide rack.

I will also take rigs off the other 77" wide rack you see inside the wooden mining closet to enable me to take it apart in order to build the much larger mining room with 3 x 77" wide racks and one 48" wide rack.

The top 3 shelves on that rack straight ahead are Sapphire R9 Fury's and RX 480's on the lower rack.

https://i.imgur.com/z3exdVx.jpg

Another view of the right side of that wooden mining closet that's about to be dismantled in order for a much larger mining room to be constructed with a total of 42 x 20" box fans.

https://i.imgur.com/mSr83kh.jpg

STILL AT MY PLACE -

A look at the entrance to the wooden mining closet and the left side.  This was a poor design in regards to the fans not having a proper frame built around them to keep heat from being sucked back around the sides, top and bottom to blow back onto the rigs and recirculate heat like a convection oven.  That will not happen any longer once I get the Fan Frames built like what my dad and I have done at his place.

You can see here to the left side of this wooden mining closet how the box fans are NOT SEALED around the top, sides and bottom.  This allows heat to come around the top, sides and bottom of each fan to recirculate back onto the rigs.  The warm air only makes the rigs get warmer and warmer like a convection oven.  Hence, the new design to combat the heat this summer.  You saw in the first photo of my place how I mentioned the rack straight ahead already had a new fan frame with 12 x 20 inch box fans properly sealed around the fans to keep heat from being sucked back into the fan around the top, sides and bottom.

Reminder:  This wooden mining closet will be dismantled and another 77" wide rack placed where you see the entry door.  On the left side of that wooden closet is where a new 48" wide rack and a 30 inch door will be installed.  So, entry will be on the side instead of the front on this next remodel.

https://i.imgur.com/EVGP2fv.jpg

I really like the mechanical build here, but I must say that is some fast cabling work.  :D

Keep up the good work.

ROFL...

If you're referring to my place where I have cords going EVERYWHERE, it's this way because I'm in a BIG HURRY while the weather is still cool.  It can get to 65 degrees Fahrenheit outside and be 90 degrees in the mining room.  It won't be like that when I'm finished with it just like what my dad and I have done at his place.  Only mine will have 3 x 77" wide racks and 1 x 48" wide rack.  His has 1 x 48" and 1 x 77" wide rack.

I'm ALSO trying to keep as many rigs mining as possible without downtime WHILE doing this remodel.

I will be Soooooo happy when I have my 4th remodel completed.  This should do the job for sure.

You said, "Keep up the good work...."

I'll do my best....   :D

PS - IF you scroll down in this link, you'll see my 2nd build in 2014:  https://bitcointalk.org/index.php?topic=766998.40 (https://bitcointalk.org/index.php?topic=766998.40)

Great use with those cheap readily available box fans. I like that fan rack alot.   Glad to see another dad get involved. My dad is 60 and have been mining since 2014 too. But he was building computers since the 70's  It's in his blood.

My wife still doesn't understand it.  Great job OP.

Thanks for your kind comments, GbrilliantQ.  Much appreciated.

Yes, the fan frame with 12 x 20 inch box fans does a great job getting the heat away from the rigs.  However, I've found it's extremely important to have everything sealed in to create a hot isle and cold isle [So to speak].  In this case; a hot room (area) and cold room (area).  It's also important to have the means of getting out the heat in the hot room (area) with a proper exhaust fan.

When I've completed the 3 x 80 inch wide fan frames and 1 x 48 inch wide fan frame for a total of four racks [With everything sealed in properly, I'm hoping my current 7,800 CFM fan used for exhaust will be enough to suck the heat out of the hot room (area).  I'll know when I check my thermometers inside the hot room (area) and cold room (area).  It may be I will have to upgrade my exhaust and intake from 7,800 to 16,000 CFM.  Time will tell...

Yes, it's cool seeing my dad finally getting involved in crypto.  He will see how addictive mining can be soon enough.  He's still kind of cautious in regard to the ability of mining being able to provide extra income.  I think what has him more cautious at the moment is his concern about the U.S. government possibly coming down on crypto in the future.  I believe we'll be fine in that regard.  Only time will tell...

Thanks for dropping by...

NOTE TO OTHERS WHO VISIT THIS FORUM:

PLEASE FEEL FREE TO SHARE YOUR MINING ROOM AND/OR THOUGHTS WITH TIPS AND PHOTOS.  THE MORE THE COMMUNITY LEARNS AND SHARES WITH ONE ANOTHER THE BETTER CRYPTO WILL BE SECURED.

Cheers and Happy Mining.

I noticed this forum has been moved to a different board other than bitcoin mining; even though SOME bitcoin mining rigs will be included with this mining setup.  Oh well...

More updates with photos will hopefully be posted by Sunday.

Happy Mining!

More accomplished last night in MY mining room.  I was able to remove 3 remaining rigs off a rack inside the old wood mining closet and placed on another rack just outside of it.  Then vacuumed the floor a bit.

https://i.imgur.com/Wli0pyF.jpg

an image of the other rack just outside of the old wooden mining closet.  It has 5 more empty spaces for 5 more rigs.  Then I will simply box up the remaining rigs to setup after the old wooden closet is dismantled and the new LARGER mining room is constructed.

https://i.imgur.com/j5E1xOP.jpg

Quite a bit of the OLD mining closet has been dismantled.  I plan on getting supplies to start the NEW and finish up dismantling the OLD later this afternoon.  The black marks on the walls are where I painted staircase spindles while it was raining a few years back.

https://i.imgur.com/pORqaCJ.jpg

One more view of that 48 inch wide rack that's full this time.  It wasn't the last time I posted a photo of it.  RX 480 8GB and Sapphire R9 Fury's on this rack mining ETH.

https://i.imgur.com/VvFW824.jpg

Super impressive mining room!!!

I curious, what is the temperature inside the room? You might have mentioned in in the posts somewhere but do the fans extract air from the room or blow air into the enclosed room?

Also as a security measure I presume you do run smoke detectors? I'm paranoid with my 3 card rig, I can only imagine you sleep very light enclosing all those cards in a wooden room?

Wow, no words, impressive to say the least!

The temperatures were getting too hot in the OLD wooden mining closet when it was packed with 2 x racks having 5 shelves on each rack FULL of GPU's.  There were approximately 205 x GPU's inside that OLD mining closet at one time.

THEN, I later added ANOTHER rack outside the mining closet with another 77 x RX480 GPU's (11 x RX480 rigs).  I have a total of 13 x RX480 rigs.  The temperature REALLY got hot then.  That's when I decided I was desperately in need of another remodel.  Cause it would get up to 109 to 111 degrees Fahrenheit with all rigs running during the summer.  Which forced me to turn off about 6 rigs during the day time during the summer and back on during the evening.

My original design on the old closet was poor.  As it allowed heat to come around the top, bottom and sides of the fans and get sucked back into the fans; only to recirculate the heat back onto the rigs [Making them even hotter] AND THAT WOULD RECIRCULATE [Making it even hotter]; till it became like a convection oven.  That's when I came up with the design for the WALL OF FANS PERFECTLY SEALED AROUND EACH AND EVERY FAN to keep heat from coming around the tops, bottoms and sides of the fans.  I tested it on one rack of fans and checked the temperature on each rig and found to my amazement they ran MUCH COOLER.

Here's what the OLD design looked like without sealing the sides, tops and bottoms of the fans.  The fans were just sitting on top of 2x4's and not sealed at all to keep heat from coming around the back of the fans and getting sucked back in to blow on the rigs [Making them hotter and the room hotter].

https://i.imgur.com/tYbPZnf.jpg

A "WALL" of fans for EACH RACK will work MUCH better [In this next photo].  I used 1"x4" to rest each fan on in this frame.  I like the 1"x6" we used at my dad's place better.  So, I'm doing the remaining fan frames for the other racks in 1"x6" and using small 1 inch "L - Brackets" to hold the fans in the frames.

https://i.imgur.com/LxIan0i.jpg

PERFECTLY SEALED around EACH fan:

https://i.imgur.com/qS10ndx.jpg

A look from the other side of the wall of fans:

https://i.imgur.com/KLULKyE.jpg

Those super hot temperatures last summer was when I made up my mind to dismantle the OLD and reconstruct a NEW closet that was much larger than the old one with 4 x racks having a wall of fans on each rack.

My Dad recently decided he wanted to get into crypto mining.  That's when I went over to his place and helped him build his according to my recommendations.  I'll make it to his place later on this week to get some rigs going that I gave to him from my place.  Because I added 11 x NVIDIA 1080 Ti rigs with 6 x 1080 Ti's per rig.  So, I gave him eight (8) of my old R9 380 rigs with 6 cards per rig which were replaced by the 10 x 1080 Ti rigs.

The temperatures should work quite well this summer.  We'll know for sure when I complete it and summer arrives.  Although, I'm quite certain it's going to work this time after seeing the improvement to the temperatures of rigs I had placed on that rack with a NEW wall of 12 x 20" box fans perfectly sealed.

Yes, I had a smoke detector inside the old mining closet and one outside.  I will have 3 smoke detectors inside and 2 outside the NEW mining room when it's completed.  I also have a fire extinguisher designed specifically for electronic equipment to keep from ruining the hardware in the event of a fire.

I have one 30 inch in diameter 7,800 CFM fan for exhaust out of the mining room and one 30 inch in diameter 7,800 CFM intake for the mining room.  There will be a total of 42 x 20 inch box fans when it's completed.  Each one of those are approximately 1,800 CFM on high.  I will probably be able to run them on medium or low this summer.  At least that's what I'm hoping for.

I'm not scared at all with having them in a wooden mining room.  The only thing that will be wood in this NEW mining room will be the exterior shell of the room.  Because the interior guts will be metal racks and tile floor.  I will be adding small pieces of fire retardant sheetrock underneath each motherboard when I finish constructing the mining room.  Just to feel a little more at ease.  The good thing is I'm not running ASIC's in my mining room.  If I were, I would be more concerned about fire.

If you're wondering what's up with the black marks on the wall in the mining room, that was from painting these cast iron staircase spindles when it was raining outside a few years back.  I was going to paint that wall a different color anyway.  So, I thought, "why not... it's raining and I needed to get it done."

https://i.imgur.com/JiriLrO.jpg

Agreed. That's the best advice for heat management. You have to move the heat off the cards.



Love everything about your setup! I know fire risk is extremely low but I mounted one of these above my rigs the other day. However, now I think I'm more worried about it discharging than a fire - cleaning it up would be a mess.

Thanks!  Much appreciated.  Still a work in progress.  Looking forward to completing it and sharing photos of it completed.

Yeah, I would be worried about it discharging on it's own without an actual need for it to do so.

Here is the extinguisher I have:  https://www.amazon.com/gp/product/B003TPOU5O/ref=ox_sc_sfl_title_23?ie=UTF8&psc=1&smid=A30XU5Y510T9EB

Well, I have the OLD mining closet dismantled [For the most part].  All that remains are some joists I made for the ceiling of the OLD mining closet.  I have not decided yet if I will take only a portion of those down or all of them down.

Yes, the power cords, PDU's and ethernet cords (Cat6) are a complete unmanaged mess.  However, it will look VERY organized and clean when I've completed this.  It's more important to me I keep everything mining at the moment to avoid losing revenue.  I'll get back to it again later this evening.

Cheers and Happy Mining!   ;D

Next on the agenda for tomorrow will be to clean out some other stuff against a wall to make room for setting up ANOTHER 77" W x 72" H x 24" D four shelf rack system.  I have a lot of plywood and 2"x4"x8' pieces of wood from the OLD mining closet I need to get out of this room to provide room for constructing the NEW rack system for proper cooling this summer.

Here are three photos to give you an idea of all the stuff I "must" get out of the way in order to construct the NEW cooling rack system for the three (3) remaining racks [One of which needs to be put back together]:

In this photo you see several sheets of plywood, 2x4's and a make-shift temporary table I had set up about two weeks ago when I was sitting in here proper clocking my new NVIDIA rigs for better power efficiency:

https://i.imgur.com/Q4zj7Bp.jpg

Just outside the French doors [Which is the entrance to the mining room] you see a heap of wood stacked on the floor from the OLD mining closet that I need to get put away in the garage:

https://i.imgur.com/zaTXsYN.jpg

In this photo you see that 77"W x 72"H x 24"D rack I need to set back up in here.  I also need to take down that other small rack behind the door [Which will be used in the construction of the NEW cooling rack system.  A "lot" of stuff is on the shelves of that rack behind the door in which I'll need to find a place to put it away in the garage.  I already have seven racks for storage in the garage.  I suppose there might as well be 8 racks now.  ROFL.  :D

https://i.imgur.com/cv785Yo.jpg

Great work OP! Thanks for documenting and sharing the photos with us.

I use a lot of those Lasko box fans. In my experience, the temps stay cooler buy placing the box fan above the rig blowing directly onto the GPU's. I find it's 2-5 degrees cooler that way instead of blowing the air from behind.

Sure, Happy to document and allow others to learn from my experience with previous remodels and this remodel.  I want others to learn from my success and/or failures.

I can agree with you there.  However, because of how many rigs I have AND the layout of my mining room, I'm FORCED to do it the way I'm about to do it in order to keep the temps down in the mining room {And therefore the entire house}.

What kind of exhaust fan are you using?  I had my airflow problem fixed in my head until someone pointed out that intake and exhaust shouldn't be through windows on the same wall.  Makes sense, it just didn't cross my mind until someone brought it up.

I think my new plan is to exhaust the heat through the ceiling into my attic.

Except for one circumstance.  Where you have a hot isle/area/room AND a cool isle/area/room.  Also, my intake and exhaust fans are 20 feet apart.  Meaning, the intake is not sucking in heat from the exhaust.  I'm currently creating the hot and cold isles in this remodel.

The fans are TPI Corporation; manufactured in Tennessee, United States.  https://www.tpicorp.com/uploads/2/2/3/3/22337256/electrical-f.pdf (https://www.tpicorp.com/uploads/2/2/3/3/22337256/electrical-f.pdf)

I purchased mine on Amazon.  It is 30 inch in diameter and 7,800 CFM.  They make a yoke mount and stand mount.  I have two of them.  One for intake and one for exhaust.  They have worked 24/7/365 since September, 2014.  Very well made and durable fan.

I was recently asked in a PM, "How are you calculating the cfm that is required of your exhaust system?  Or the number of air changes needed per hour?  Are you approximating it on a per gpu basis?  I can do the math from cfm of a fan to air changes per hour based the cubic feet of my mining room, but I'm not sure what goes into calculating the cfm or air changes per hour that my set up will require."

My response:

As for calculating the CFM required for exhaust, I have not done any such calculation(s).  I have no idea of number of air changes per hour.  If one wanted to know the number of air changes needed per hour, I believe they would ALSO have to decide WHAT TEMPERATURE would be the "mean temperature" they want to achieve in order to come up with an answer.

As for what "mean temperature" would be ACCEPTABLE for rigs to mine efficiently and/or effectively, that would also have to be determined by the operator.  It can be 100 degrees Fahrenheit in the room and the mining cards still mine fine.  However, I do not want the temps that high in the mining room.  Mainly for humans to be more comfortable [Temperature wise] in the house.

I'm shooting for mid to upper 80's [Fahrenheit] in the mining room with outside temps at 100 degrees Fahrenheit this summer.  That's with bringing in outside air with the intake fan.  Keep in mind, the outside air will be cooled as it is accelerated through the intake fan into the mining room.  Hence, the lower temperature in the room.  I would "accept" the ambient temp in the mining room in the 80's [Fahrenheit] this summer.  I would be "ecstatic" with those temps this summer.  That would put my GPU's in the low 50's to low 80's Celsius range [Depending on the GPU].  For example, my REFERENCE RX 480's already run at fairly high temps Celsius compared to GPU's with multiple fans.

I may be forced to get higher CFM intake and exhaust fans this summer.  I'm not sure yet.  Hence, the reason for your question(s) on calculating the CFM air changes per hour equation.  I've always been one to learn the hard way [Via experience] rather than by math in regards to temps in the mining room.  I'm "winging it" so to speak.    ;D

With the mining room currently at 99 degrees Fahrenheit, my EVGA NVIDIA 1080 Ti rigs are at mid 60's to upper 70's [Depending on location of GPU].  Why am I saying, "...depending on location?"  My 1080 Ti rigs sitting on a rack with my newly designed fan frame for 12 x box fans are currently mid 60's.  While the other 1080 Ti's [With fans but NOT with newly designed fan frame] are mid to upper 70's Celsius.  It's only logical to conclude if I had the entire rack system of four (4) racks properly sealed with my new design of fan frames TO KEEP HEAT GENERATED BY THE RIGS FROM BEING SUCKED BACK INTO THE BOX FANS AND BLOWN BACK ONTO THE RIGS; the rigs would run much cooler.  The main reason the mining room is 99 degrees Fahrenheit currently is because racks are sitting out in the open with no new fan frames on them to SEAL in a HOT ISLE (area/room) to separate from a COOL ISLE (area/room).

By the way, when I said, "One would need to determine what mean temperature would be acceptable to them," I was referring to the COLD ISLE (area/room).

I currently have NO COLD ISLE (area/room).  All the air brought in from outside is currently being mixed with heat from the rigs and sucked into the box fans to blow on the rigs.  Hence, the reason for my design to seal off the outside air brought in via the intake fan FROM the heat generated by the rigs BY CONSTRUCTING the fan frames for each rack with properly sealed frames around each fan to keep heat from the HOT ISLE (area/room) from getting out into the COLD ISLE (area/room) and heating up the COLD ISLE (area/room) to make the air no longer COLD but warm or hot.  Which would get sucked back into the fans and onto the rigs.

BACK AT MY DAD'S PLACE:

All the frames for each 20" box fan were sealed on this fan frame wall for the 77"W x 72"H x 24"D rack on the inside of the mining closet.  Each square will be opened to place a fan inside AS NEEDED when rigs are added.  Weather stripping was placed in the opening of EACH square before placing 0.5" thick plywood over the opening.

https://i.imgur.com/nHuYTu0.jpg

STILL AT MY DAD'S PLACE:

6 of the 8 x 20 inch box fans have been installed on this fan frame wall for the 48"W x 72"H x 18"D rack.  Two more to go in on the bottom before it's completed.

https://i.imgur.com/1UBYJsX.jpg

This is to give you a look at what I mean when I said weather stripping was carefully placed in EACH opening for box fans.  Wanted you to see the weather stripping before completely closing it in with fans.

Don't mind the hardware that's covered by sheets to protect from dust.

My dad and I both have to complete our business taxes for 2017 before getting back to work on our mining rooms.

Happy Mining!

How about decibels of each?

I would have to get a decibel meter or app [For iPhone] to read the level.  Remind me in the future to do that.

Here are the specs on the 30" model by TPI that we installed.  However, the decibel spec is not included:

I have two of these in my mining room that have been running 24/7/365 since September, 2014.

Link to their product page:  https://www.tpicorp.com/uploads/2/2/3/3/22337256/electrical-f.pdf (https://www.tpicorp.com/uploads/2/2/3/3/22337256/electrical-f.pdf)

https://i.imgur.com/OZnm7WO.png

It is very important to keep things in check concerning decibel level. All must be level up in equal terms.

What must be "level up" in regards to "decibel level?"

Explain...

Great topic and photos. With all these fans exhausting air, do you not worry about security? I.e not only someone trying to break in to steal your GPUs, but people breaking in thinking its something else (Cannabis farm etc.) ?

ROFL...

The only fan seen at my place is an exhaust.  However, it's in the back of the house facing the back yard which is also fenced in with a 6 feet high privacy fence.  The other fan for intake is underneath the deck and NOT seen while also being in the back yard.  If ANYONE is in my LOCKED fenced in back yard without my permission, they're risking getting shot.

My weapon of choice:  30 caliber that also shoots arrows.  I would prefer to use the arrows on an intruder to keep the noise down from waking up neighbors.  It has one scope for .30 caliber pellets and another scope for arrows.  Two different barrels:  One for .30 caliber pellets and one for arrows.  The barrels simply screw on.

https://i.imgur.com/71lybnh.jpg

Video (Time stamped to 492 seconds) to show you the difference between this and a bow.  Much more accurate than a bow and it's explained why: https://www.youtube.com/watch?v=z_DsjavaufI&t=492s (https://www.youtube.com/watch?v=z_DsjavaufI&t=492s). There are also other toys at the house ALWAYS on the ready against "would be" intruders.

It also helps having a WIRELESS security system MONITORED by Simpli-safe.  https://simplisafe.com (https://simplisafe.com)

I have the same WIRELESS alarm attachments for windows and doors placed on the fans on exterior walls.  Meaning, if someone TRIES to pull out or push in an exterior fan to get into the mining room, they set off an alarm just as if they opened a door or window.

My dad's mining room is in his garage and NO WINDOWS.  Hence, the exhaust to the attic.

wow how many gpus have you installed?

At my place I have the following:

12 x EVGA NVIDIA 1070 Ti FTW2
52 x EVGA NVIDIA 1080 Ti FTW3
12 x XFX R9 390
36 x Sapphire R9 Fury
24 x R9 380
89 x RX 480
7 x RX 580
TOTAL OF 232 x GPU's at my place.

I gave my dad the following OLD rigs:

48 x R9 380's
7 x Bitmain S7's

He will also be purchasing some NVIDIA's very soon.  I plan on giving him my remaining R9 380's as I replace them with NVIDIA cards.

We will not get all of his cards going until after we both have our business taxes done.  He's NEW to this.

Oh...myyy...goddddd.... You have a lot of gpu’s.
Insane. So jealous :)

Nice to see father and son on mining adventure :)

It's been a learning experience for sure with mining.  I'm still learning...

Yes, I'm happy my dad is FINALLY getting into mining.  I've been trying to coach him into mining in a nice way for the past 3 years.  He finally asked me about mining approximately 30 days ago.  So, we kind of dove into it shortly after that talk.

I suppose I have a lot of GPU's for a "home miner" with only 225 Amps service.  I hope to either upgrade my power at the house OR lease a small warehouse for cheap near my house by this time next year.  Which means, I plan on expanding my mining even more; as profits allow.

It's important for ANYONE who mines to also become a fairly decent trader in order to optimize profits from mining as much as possible.

Lovely work I must say - I'm impressed (and a bit jealous!).

Thank you!

Much appreciated.

I'll be very happy when it's completed.  I'm currently involved with business taxes due on March 15th.

How do you like the Simpli-safe system?  My house is already wired with an alarm service, but i'm looking for something to monitor the windows I had to use has intake/exhaust ventilation.

I'm loving it!!!

Easy to set up.  Uses batteries [therefore wireless].

The base lets you know when the batteries are getting low.

The base uses cellular to communicate with simplisafe if you have them monitor it.

You'll love it if you get it.

 Thanks!  Been curious since I've been seeing a ton of social media marketing on it.

Sure... You're welcome.

Thanks for the reply, great info there. Looks like an awesome gun you have - they are illegal in the UK (or more so, you can't shoot someone on your property) but it makes perfect sense in the US. Its a shame I'm not in the US as I'm currently looking for someone over there to potentially start up a mining data center with. I don't think I'm quite big enough to do it on my own at the moment (currently running 100 Vegas) but if two of us pooled together it would be much more achievable.

Well, [Depending on the State you live in] you have to be very careful about shooting someone on your property compared to inside your home.  They have to actually manifest threatening actions to your life in order for you to legally shoot them in your yard.  That's why I said they are "subject" to get shot.  Not that they will get shot.  If they advance towards me as if to attack me, they WILL get shot.

I'm not currently as big as I want to be in mining yet either.  I'm hoping to get a loan in the near future [Between May and July] to double my farm size at a minimum.  I'm wanting to stay alone rather than team up with someone else.  At least that's my plan currently.  If I had over $1,000,000 worth of hardware, my thoughts my change.  Otherwise, I'm staying alone for now.

100 Vegas is a nice little farm.  I know they bring in a decent amount of revenue with ETH and/or XMR.

That's cool that you're doubling your farm size. Have you actually got room to do it?

Well, "hoping" to double it.  Will need the loan first.

I have the room in my mining room in the house to add eleven (11) more rigs.  More than that and I will have to build a shed in the back yard or lease a small warehouse.  I prefer to have a shed built out back.  I'm considering a 16 feet wide by 32 feet long by 17 feet high to be built in the back yard "IF" I can get a loan.

I may be forced to wait till this time next year by depending on profits made from mining and trading the remainder of this year.  However, the profits I make from mining and trading this year may only be enough to replace the remaining AMD rigs I have with NVIDIA rigs "WHILE" leaving my AMD rigs off-line for a few months.  Once the new year (2019) begins, I'll have to wait a few more months for profits to accumulate to build the shed out back and get a power upgrade.  Again, this is WITHOUT a loan and assuming revenue/profits from mining and trading will be similar to previous years.

Then once the shed is built and power upgrade installed, I would be able to move EVERYTHING to the shed and get the AMD rigs online.

So here is what I currently have going on ...

https://i.imgur.com/pDD5B5Z.jpg

https://i.imgur.com/Z932XXp.jpg

https://i.imgur.com/hWPHSyi.jpg

31 GPU's ranging from 1070ti's to 1080ti's ... Six of them are XFX Vega 56 blower cards.  According to fan specs, we're doing 3100ish cfm on intake and exhaust in a room that is 1680 cubic feet.  There is another window in that room that I could put another intake fan in, not sure about that yet.  If I do that, I assume I'm going to need to put in another exhaust fan.  All rigs other than the vega blower card rig have a box fan behind them. 

I'm wondering if I should move the shelving unit a little closer to the exhaust, so the heat is sucked directly upwards, but the box fans are pushing hot air off of the cards in a forward motion.  Not sure how much.

Currently the room is around 7-8 degrees above the outdoor temp.  Without the exhaust fan (and with the intake and box fans), it was 15-18 degrees above the outdoor temp, so it has certainly made a big difference.   

Temps here are going to be heating up, so we will see what happens.  The next step in this project is venting all the way outside rather than into the attic. 

If anyone has any suggestions on gable vents or roof vents that have fittings for a large diameter hose, please let me know.

That room looks sexy just like the OP mining set up.

If I had this set up, I would have the 2 windows with exhaust fans (attic gables fans) sucking hot air outside on boths windows and I would put that shelf with all the rigs on it right in front of it. So it would go like Cool Air--Rigs--Attics gable Fans sucking the hot air out.

I would keep the ceiling exhaust fan also just to make sure that there isn't any trapped hot air anywhere. You can never have to much exhaust. Just make sure you have a source for fresh air (does not have to be AC air but needs to be fresh)

That window fan can be used for for exhaust.  Just have to turn the knob on it to one of the exhaust settings.  I looked at attic gable fans, but I like that this one is made for a window.  Problem with using it as exhaust is I have no other source for intake, if I do that.

If I were you, I would just split the ductwork in ceiling to create another exhaust that's over your rigs instead of moving.  Having the exhaust over your rigs can also help move more of the air towards your rigs.

Maybe I'm not understanding exactly what you mean ... But why would you go to all of that trouble, when I could easily move the shelving unit a few feet to position it directly under the exhaust vent in the ceiling?

Sweeeeeeeet,

I see we have some posts.  I've barely had time to check my email.  My County Electrical Inspector is making my electrician replace a meter box with a new one (installed correctly).  This has held me up a bit in regards to revenue.  I've been missing out on revenue since Wednesday, Last Week.  It is now Wednesday, Next Week.

You can see an image here of the off-set they need to make it look halfway decent.  I appreciate the inspector looking out for me there so it doesn't look like crap.  However, this will instill some sneaky power connection with whips.  Simply means the downstairs is off limits to my seven year old for now.

https://i.imgur.com/7StDK7m.jpg

As far as the mining room goes, everything is pretty much disconnected and getting ready for remodel to obtain better cooling for mining during the summer.  I will send a string of one image after another with a few comments.

https://i.imgur.com/dlwRIDx.jpg

This one rack will be left alone because it is already placed where it will remain and already has a 12 box fan frame built and attached on the back of it:

https://i.imgur.com/gAwSXiC.jpg

https://i.imgur.com/LxIan0i.jpg

Another 77 inch wide rack is about to be setup inside here and the rigs on the 48 inch wide rack will be transferred over to it.  The 48 inch can hold eight rigs.  The 77 inch wide rack can hold 12 rigs at 3 rigs per shelf.

https://i.imgur.com/Ycr0AAr.jpg

Another sad view of rigs sitting idol.   >:(

https://i.imgur.com/F63Dkxu.jpg

Yeah, I found I had to make different rooms for best efficiency possible.  A room for heat and a room for cool.  You cannot allow the heat generated by the rigs to mingle with fresh cool air.  Otherwise, it will heat up the cool fresh air before it is sucked into the fan which blows warmer air onto the rigs.  The rig gets warmer; the air coming off the rig gets warmer, the room air gets warmer; the warmer room air blows on warmer rigs to release even warmer air in a big circle like a convection oven recirculating heat.  At least this is what I determined once I got over 100 cards.  I have over 200 cards now.

No idea on who to contact for the roof vents.  Good luck.  My dad had to rig stuff up his own.

Did you notice the photo of the exhaust fan my dad and I installed in his ceiling inside the mining room?  Did you notice how spaces were made for box fans to keep all heat inside that room separate from fresh air coming into the garage.  This way, the rigs are not sucking in hot air that heat they released may have mingled with.  There's no chance for the heat from rigs to co-mingle with fresh air with that design in his garage.  The racks act as bracing for your wall.  Simply attach some 2"x4"'s to the racks and start building... adding doors, etc...

This photo below is the 30 inch 7,800 CFM Exhaust Fan in my dad's mining room.  I have two of those at my place [One for intake and one for exhaust].

https://i.imgur.com/sgvSD2s.jpg

I got two sticks of 3 inch in diameter Electrical Gray PVC pipe to act as "sleeves" for 9 x 30 Amp Circuits and 4 x 20 Amp Circuits.  I'll use a smaller 1.5 inch Gray PVC pipe for comms.

https://i.imgur.com/ZXdcyk3.jpg

That is a pretty sick mining room. I love the custom built mining rig cases. Seems like a good combination of wood and aluminum(?). Although some might say that all the wood is a big fire safety risk. You mind me asking what GPUs are you using? Seems like you've diversified into both AMD and NVIDIA.

All the wood is a big fire safety risk.

Pardon me, but if you know what you're doing with open air PC builds, you should have no problem.  I would be more concerned with ASIC's than I would open air PC builds.  But that's me...

Anyway, all of this will be done properly.  I will even have each rack grounded with #4 Copper ground wire to the "Bridged Ground" outside at the power meter and Main Distributing Panels.  I've been mining since 2014 (The days of the Bitmain S1 and S2).  I've also owned S3, S4, S5 and S7.  I never did own the S9.  I bought GPU's instead; after selling most of my S7's.  I gave the remaining 7 x S7's to my dad.  I had a total of 42 x S7's at one time and not enough power to run them all.   :D :D :D

All of this is going to be done right in my remodel.  It will be organized similar to the way my dad's was organized; only two more additional 77 inch wide racks with fan frames on the back of them like the one in the back.

Still more work going on:  More updates to continue every so often...

https://i.imgur.com/vV05Iu0.jpg

https://i.imgur.com/aDPfgeJ.jpg

Thanks, appreciate it.  I "hope" it will be to everyone's liking when completed.  I have other things I could have done with plexiglass and LED's but that will have to wait a while.  It's not a fire safety risk to me.  I have several smoke alarms, fire extinguishers, I'm ready.

Currently what I have at my place:

12 x EVGA NVIDIA 1070 Ti FTW2
52 x EVGA NVIDIA 1080 Ti FTW3
12 x XFX R9 390
36 x Sapphire R9 Fury
24 x R9 380
89 x RX 480
7 x RX 580
TOTAL OF 232 x GPU's at my place.

2 x Sapphire R9 Fury rigs and 1 x NVIDIA 1080 Ti rig is in the office in addition to what you see in the mining room I'm remodeling.

I gave my dad the following OLD rigs:

48 x R9 380's
7 x Bitmain S7's

He will also be purchasing some NVIDIA's very soon.  I plan on giving him my remaining R9 380's as I replace them with NVIDIA cards.

That is a pretty awesome project you worked on with your father. Nice.

Those RX 480s are pretty much the dream GPUs. How long have you been mining for? Congratulations you probably don't have to work a regular job for the rest of your life by now eh.

I would also love to know why you are still mining with power hungry R9 Furys. Is electricity so cheap at your location that they still give you a decent profit (for all the risk vs resale value)?

Yes, the R9 Fury's are VERY power hungry.  The best price to power ratio with Fury's and a BIOS Mod is ZEC at approximately 420 Sol's each and 130 Watts.  Currently mining ETH at 32 MH/s each card.  Not sure how many watts.  I'm sure I could make them hash faster.  Took them back to factory BIOS with ETH.  Thinking about using AMD software to make them more power efficient.  I'm holding on to them as long as they keep making me money.  :)

I bought most all of my 480's the first couple of months they came out.  They've ROI'ed at least 3 times over.  The price I paid for those 480 8GB's was literally half of what most people paid for their 580 8GB's.  I paid $145 each for the R9 380 4GB's back in May and June, 2016.  They ROI-ed 3 times over.  I had 78 x R9 380's at one time.  Along with a lot of Fury's and R9 390's.  I've had the NVIDIA's since July and August for some and the remainder in December.  I paid between $600 and $820 for most every EVGA 1080 Ti I have.  They were going for $1,200 "Used" quite easily a few months back.

I haven't worked a regular job in a long time.

I can tell he has enjoyed it.  I too have looked forward to working with him on his crypto currency journey.

In this photo you are seeing the back side of these racks that do NOT have the fan frames built and mounted like on the one in the back.  That's what I have to tackle next are those fan frames with 12 fans in each frame for each of those two racks.

This post is to simply show my 30 Amp circuits are currently TEMPORARY.  The inspector will be here tomorrow morning to inspect for the last time, hopefully.  THEN, I can finally make these circuits permanent.

By the way, I will be taking out those temporary 30 Amp circuits before the inspector arrives in the morning.  The only reason they are hooked up now is to avoid losing too much mining revenue.  If I installed these circuits into the new electrical panels, the inspector will also want to see the room(s) they were installed to inspect the outlets as well.  I don't want an inspector in my mining room with the current shape/predicament it's in.  No?  :)

Not sure if any of you saw one of my builds for 6 x EVGA 1080 Ti KINGPIN's.  I have 5 x EVGA 1080 Ti KINGPIN 6 card rigs and 4 x EVGA 1080 Ti FTW3 6 card rigs.  I absolutely love these EVGA 1080 Ti KINGPIN's.  The copper heat sinks on these baby's are absolutely gorgeous!  Here are the specs for the KINGPIN's:  https://www.evga.com/articles/01116/evga-geforce-gtx-1080-ti-kingpin/ (https://www.evga.com/articles/01116/evga-geforce-gtx-1080-ti-kingpin/)

Here it is without the PSU and Motherboard shortly after painting it with copper spray paint to match the copper heat sinks:

Simply showing progress of what's coming along with the first fan frame that will hold 12 fans.  Looking at it, you might think it will only hold 9 x 20" box fans.  

What you are seeing in the picture will be the top 3 levels.  This top level is not completed yet.  Getting close though. 

The lowest level will be built and attached last.  I cannot get it through the door into the mining room if I built all 4 levels.  I do not have enough room in the mining room to build it in there and bring it around the other side to put in place.  Just not enough room.  Hence, doing it this way in two sections.

When I bring the shortest lower section into the room, I will need to raise the upper section off the floor and slide the lower section underneath to attach it.

https://i.imgur.com/f96Bnca.jpg

This photo is a reminder to give you an idea of what I'm putting together:

https://i.imgur.com/LxIan0i.jpg

And a look from the other side:

https://i.imgur.com/KLULKyE.jpg

I drew this last summer when I was forced to cut off several rigs during the day in the summertime and back on in the evening.  I still have a ways to go yet.  However, one major thing I'm doing different.  On the far left you see a door for entrance into the mining closet.  That door will be moved closer to the French doors to allow a 48" wide rack to be placed there.  Also, the intake and exhaust fans in the windows will be doubled up.  Meaning, I will have two 30" intake fans and two 30" exhaust fans.  Maybe not till next summer.  Mainly for redundancy in case a fan goes down for whatever reason.  This way there is still another one going till the one that is down can be repaired or replaced.

https://i.imgur.com/GWxu9wq.jpg (https://i.imgur.com/GWxu9wq.jpg)

Nice work! I would love to have more rigs and I'm adding them slowly. I put my mining in a shed outside after the heat was so bad in my house. I did a write up of the project here if anyone is interested:

Scroll down to the shed write up, it's after the Octominer build.

Hi Canefire,

Thanks for dropping by and sharing!  Much appreciated.  I'm about to get some shuteye.  I did take a quick look at it.  However, it looks like it's worth reading instead of only looking at photos.  I'm going to read it tomorrow and make comments here either tomorrow or the next day.

Cheers and Happy Mining!

You inspired me to make my setup better. I am in the middle of building a house. My small mining room will get me by until I expand to a dedicated space for mining. I bought some flap vent mounted fans from the tpicorp company you listed earlier for your big exhaust fan. Wall studs prevent me from going with on 30 or 36” unit so had to get 4 12” units. Having some custom ducting made.

I will start taking pictures to document it.

A little work we're doing at the mining farm.

External ventilation behind which will be two 20,000 cfm exhaust fans.

https://i.imgur.com/uf6Ifur.jpg

The peaked roof in this photo is because we're fitting two filtered 48" 20,000 cfm intake fans on this side.  This is to bring cool air into the "cool aisle".

The shelving for the rigs is in the middle wall so the cool air goes into the intake fans on this side, and through the wall to the hot aisle.

This is the hot aisle. At the end will be a 20,000 cfm exhaust fan.  At 200 cfm per miner, that's 100 miners that can fit on this side and be cooled properly.

pretty interesting read. thanks for posting link.

Yes, I "love" all the time and effort you put into doing this right!  Great job, Bro!  I'm impressed...  :)

If you ever get to a point where you add even more rigs [Enough to make you re-think your air exchange] and forced to increase air flow, you might consider cutting up about a 2 feet wide strip of plywood from the floor going the full length of the shed and attach a steel grate in place of the plywood you just removed.  Of course the steel grate would rest on top of your floor joists.  Which would provide plenty of support as you walk and/or stand on the steel grate.

The advantages of the steel grate replacing some plywood on the floor is to allow fans inside the shed to pull cool fresh air during the summer UNDERNEATH the shed [Where it's cooler].  Only a thought if you find you need to increase air flow after adding even more rigs.

Please keep us updated with any changes, additions, new hardware, etc... in the future.

Thanks again for sharing, Canefire!

Hey thanks for the feedback! I did think about doing the intake on the floor but couldn't get my head around the filtering issues if I put it there. I liked the shade idea a lot though, and I have now built a "trellis" on the exterior of the intake wall two feet away. I planted some fast growing vines (honeysuckle) which will in theory grow very fast and shade the entire sunny wall after a few months. Not sure about this but I liked the "living wall" concept.

Another fan frame constructed and put in place with 12 x 20 inch box fans running in it.  I still need to do a couple of miner things in regards to actually physically attaching it with L-Brackets.  Other than that and better wire management for the fans, it's time to make another one...

Yeah, I can see what you mean in regards to trying to filter the floor.  That would certainly involve using your imagination with some custom work.

Sure, those honeysuckles should do the trick to cool down the wall that faces the sun majority of the day.  Good idea.  :)

I would love to have all of mine in a shed in the back yard as well.  Maybe some day.  I was trying to keep cost down by building it in the basement in my house.  If I had a shed in the back yard, it would require a decent size shed for all my rigs and require me to cut down several trees.  I have 26 trees in the back yard I want to cut down some day.

If I built a shed, I would want enough for 800 amps of hardware because I would eventually wish I had more space I'm sure.  That would be about a 16' x 32' two story shed.  I would want the 2nd story for storage.  Here's an idea of what I mean by a 16'x32' shed:  https://www.youtube.com/watch?v=-Q-KTueiQ98&t=14s (https://www.youtube.com/watch?v=-Q-KTueiQ98&t=14s)

Cool... Happy to hear that, Dagamus.  Sounds like you have a plan.  Keep us updated with photos and comments on the photos if you will please.  We all can get ideas from one another.  No?

Thanks for sharing, fittsy.  This is looking awesome man!  Certainly is...  Please keep us updated with your project.  Always like seeing what other people come up with when using their imagination.  It's truly inspiring and can generate other ideas to those who see them.

One question:  It looks like the intake and exhaust will be right next to one another with those galvanized steel exterior wall vents.  Do you have any concern with the intake sucking heat from the exhaust as it comes out?  It may still work fine.  I was only wondering...

If it does end up becoming an issue as you add more and more rigs, you may end up having to build some kind of exterior wall that's tall enough to act as a divider between the intake and exhaust vents to reduce the heat.  But again, that's only IF it ends up becoming an issue.  That was my plan if my intake and exhaust (on the same wall) were too close together.  My intake and exhaust are 20 feet apart from one another and end up working fine without building a divider wall outside to separate them better.  it may end up working fine with no issues.

Please do not think I'm being overly critical of your design and work.  I like what you have going on there and look forward to seeing more updates in the future.  I'm simply asking legitimate questions to see if you thought about it and find out if you had a plan B if it ended up becoming an issue?

Yeah, that is a bit confusing as I didn't post a photo of the other side of the building.  I don't think I have that photo on this computer.

The intake vent is a different side.  It's got a peaked roof to fit two 48" 20,000 cfm filtered fans side by side.  One is on the north side of the building and one south.  We get breezes from the south so we put the intake vents on the south side and exhaust on the north side.  The photo you're referencing will have two exhaust vents side by side, not intake.

Sweeeeeeeeeeet!

Sounds like a plan.

Please keep us updated...  :)

Got another Fan Frame made.  I still need to mount a 2"x4" on each side of the rack vertically in order to fasten the fan frame to the rack to secure it.  Also need to get more 6 port extension cords as well to plug the fans into power.

I love this, how crazy ideas work and in fact its not really crazy or stupid, its like a form of resourcefulness or gracefulness in batlling heat during mining. I love how he does this. And typically can help ideas to other on how to manage difficulties as such.

Thanks!

Much appreciated!

I wish the other thread on "Miner Photo Porn" was not deleted.  I had over 500 posts in that topic alone with close to 100 photos of previous mining rooms that started out small and got larger over time.  I've experimented a LOT with best possible way for heat management since 2014.  Even tried air conditioning.  Of course, that did not work either.  The amount of money one would have to invest to have enough air-conditioning to cool down this number of rigs would be very expensive.  I have 38 rigs in total.  I have several in my office that will be placed in this new mining room remodel.  I'm just looking forward to completing this so I can move on to other things.

OMG. This is awesome

Thank you very much!  Still a work in progress...

I'm about to get back to it.

Cheers

What is the hydro service you are running this on?  400amp 240v?

Summer is on the outside, time to chill.
I am create yesterday box how tunnel and from one side screw 2 9sm fans from foxconn. Connect +to 12V - to 5V, its wroking silent but cant chill 3x RX550 AMD cards, i want buy variable resistance and search optimum fans speed.
If connect it to +12V noise is very high frm this fans

I've found [For the price paid for 20 inch box fans verses 120mm or 140mm computer fans] it is more cost effective to get 20 inch box fans.  I've also found 20 inch box fans to move more air for the amount of noise they generate verses 120mm and/or 140mm computer fans.

ALSO:  To get 5 x 120mm or 4 x 140mm fans for each rig and seal them in plywood with holes cut out would have required a lot more labor to cut out all the holes I would have required for 38 rigs.

I'm running all of this on the same power grid as most everyone else.  My power company has both hydro and clean coal power generation.

Yes, I have 400 Amp service at my home.

I have a total of nine (9) 240 Volt 30 Amp Power Distribution Units (PDU's) for the rigs and four (4) 120 Volt 20 Amp circuits for 36 x 20 inch box fans and two (2) x 30 inch intake and exhaust fans.

What is the power consumption of you box fan ? and how many graphic cards card it blow air on/off ?
I bought on AliExpress a bunchload of 14cm fan that can be used for two cards and they use only 3w so a 12 card rig can be managed with 18w (but airflow is probably lower than with a box fan)

The particular one I own is the following:

Low:  27 watts (30)
Medium: 73 watts (75)
High: 119 watts (120)

I have mine blowing on 7 cards in 23 inch wide rig cases.

The amount of heat generated from 38 open air rigs needs these box fans for the room downstairs I have them in.  And the fans need to be properly sealed around the top, bottom and sides to keep heat generated by the rigs from getting sucked back around the bottom, top and/or sides of the fans and blown back onto the rigs.  If it's allowed to do this over and over again for a long time, the rig will only get hotter and hotter like a convection oven.  At least in my case with how many rigs I have.  You would probably be alright without sealing around the top, bottom and sides of the fans if you don't have a lot of rigs.

I purchased 40 of these fans.  I have 4 spares:  https://www.homedepot.com/p/Lasko-Weather-Shield-Select-20-in-3-Speed-Box-Fan-with-Thermostat-B20573/206441059 (https://www.homedepot.com/p/Lasko-Weather-Shield-Select-20-in-3-Speed-Box-Fan-with-Thermostat-B20573/206441059)

Simply providing a photo to allow one to see the entrance to the mining room with the French doors open:

https://i.imgur.com/sL5PxM6.jpg

As you can see from the photo below, I have the sides of the racks covered with plywood.  Even the 48 inch wide rack on the left in the photo has it's sides covered.  I'm going to finish roughing in the frame and install a 28 inch wide door this evening.  I'll also install plywood on the back of the 48 inch wide rack this evening.  The door needs to be installed first because of the suction created from all the fans.  Hence, installing the plywood on the back of the 48 inch wide rack last; because of that suction.  I'm afraid the door would be more difficult to install if I installed it last because of the suction.

I need to purchase eight more fans to have on standby for the 48 inch wide rack for a future date when more rigs are hopefully added to the mining room.  Which means, if and/or when I add more rigs, I'll need to make a "fan frame" that holds eight fans for eight rigs in the 48 inch wide rack.

I'll install new electrical overhead to replace the temporary electrical you see running on the floor once the door and walls are completed.  Wire management will be saved for last.

https://i.imgur.com/VSdTrax.jpg

Here's a look at two of the three fan frames completed with fans properly braced.  You would be surprised how all the fans want to fall out of their cube without bracing if I were to turn them all on.  Found that out the hard way.   :D :D :D  The air pressure generated from all of them on pushes them out of their individual cubes.

https://i.imgur.com/dgYekGZ.jpg

New 28 inch x 80 inch door installed.  I still need to install the door knob.  The old 30 inch x 80 inch door from the old mining closet was too wide for the space available.  So, I had to go with the 28 inch door.  The old door will be stored away in the garage or trashed.  I haven't decided yet.

It took me a while to figure out how I'm going to finish the back side of the 48 inch wide rack with the old door leaning against it.  I plan to finish that this evening.  I also need to trim out the top and corners to seal them in to keep heat from escaping into the cool isle.

In case you're wondering, self tamping hex nut metal screws were used on the outside to screw the plywood into the metal racks.


https://i.imgur.com/wpl9PXe.jpg

Here's a look at the wall with the door from the inside.  Please ignore the disorganized wiring.  It will be sorted out when I add two more Power Distribution Units and one more 16 port switch.  New electrical will be ran as soon as I can get the mining room enclosed and sealed properly.

I have a nice cold basement that keeps cool even in this 90% heat.

This mining room is in my basement next to the garage.  I guarantee you if you had 38 rigs like myself, you would be FORCED to do something similar to what I'm doing in order to keep your rigs cool.  If you didn't your rigs would be shutting down a lot from getting too hot.  Not to mention how the excessive heat can shorten the lifespan of your rigs.

The following is a YouTube video of a mining shed someone built with Industrial Metal Grate on the floor to allow cool air to be sucked up onto the rigs by the fans in the wall behind the rigs.  My only criticism about the design of his shed is he probably needed a larger shed.  Why?  The exhaust for the GPU's are currently facing where the cool air comes up from the grate on the floor.  I believe his rigs would run cooler if he turned the GPU's around for the heat exhaust from the GPU's to face the fans in the wall and exit straight out the fans.

Here's the link:  https://www.youtube.com/watch?v=Bzhg0OhwZpg (https://www.youtube.com/watch?v=Bzhg0OhwZpg)

With the time you spend advocating against ZEC and their stand on ASICs while supporting miners and GPUs, i am amazed at how you can still be this efficient and be able to develop mining rigs and setups as complicated as these. More power to you. Your images and screenshots are always and inspiration for us to continue working hard and do our best in what everything we do.

You should always place your ASIC rigs in a well-ventilated room. Considering the room has some kind of air conditioning system, it should also have exit vents. These exhaust vents will suck the warm air out. So they are mostly strategically placed on the ceiling. Having a smaller room helps, but it should not be too cramped.

You deserve a medal.  I am very impressed.  I have been toying with the idea of taking some of my crypto and cashing it in to buy a shed, cover it in solar panels and then cram as much hardware inside it that the panels can handle and then adding from there, using my crypto profits of course.  Kind of like any RTS game where you have to gather resources and upgrade your units....

Thanks for the motivation to continue.

Cheers Mate,

:)

Thanks for the kind words.

I would love to have solar panels to supplement power from the grid.  However, solar is still a bit expensive.  The batteries needed to power the rigs during the evening would have to be very high amp hours as well.  Led acid batteries should not be depleted more than 50% to avoid limiting their lifespan.  That's why I like Lithium Ion batteries.  

Lithium Ion batteries can be recharged more times than led acid.  They can be depleted down to around 5 or 10 percent every time before recharging without affecting their lifespan.  They also charge much faster than led acid.  Given the limited amount of light we have in the Southeast United States [Compared to the West side], it would behove one investing in solar for mining to buy lithium ion batteries.  However, they are VERY expensive.

One would also need panels with a minimum rating of 300 watts each on a small shed to obtain as many watts per square foot as possible.  300 watt panels are not cheap either.  I would love to have 75,000 watts of solar panels with sufficient amount of amp hours in Lithium Ion batteries to run my set up.  However, it would require 250 x 300 watt solar panels at a minimum to power them.  At $250 each 300 watt panel, that would be $62,500 worth of panels.

If I wanted to run 75,000 watts an hour for the 11 hours the sun is down before recharging batteries again, I would need a LOT of batteries.  75,000 watts per hour x 11 hours = 825,000 watt hours.   825,000 watts divided by 12 volts = 68,750 amp hours.  If I had 12 volt Lithium Ion batteries at 700 amp hours per battery [Depleted to 10% would be 630 amp hours each battery], I would require 110 batteries.  Lithium Ion batteries with 700 amp hours per battery is approximately $5,000 per battery.  In bulk, I could probably get them at $4,000 each x 110 batteries = $440,000.  Total setup of panels and batteries with wiring, charge controller, etc... would easily cost around $550,000.

My estimate above could be off a bit.  I just know it would be quite expensive.  I can't imagine the space I would need for 250 solar panels.  What's worse is I "KNOW" I would require more panels than what I estimated.  Cause I would only have about 6 hours of peak sun light.  Maybe 8 hours total if you add in the off peak.  Also, I would need those 250 panels to power the 75,000 watts of rigs during the day WITH ADDITIONAL PANELS to charge the batteries for mining during the evening time.  Which means I would need more than double the panels that I mentioned if I wanted to mine 24/7/365.  So, the cost to run 24/7/365 would actually be double my estimate at $1,100,000.

The above estimate is assuming I was mining from 100% solar and no power grid.

75k watts per hour x 730 hours in a month = 54,750k watt hours x $0.10 cents per kWh = $5,475 a month if on the grid.

$1,100,000 for solar set up divided by $5,475 per month of grid power at $0.10 cents per kWh = 201 months divided by 12 months = 16.75 years to pay off.

I'm sure philipma1957 would know much more about solar than I do because he's currently mining with solar.  Consider mine a rough estimate from little experience.

Batteries have always concerned me, I was thinking of using net metering as my method of running at night.  Basically feeding the utility company my excess electricity and receiving a credit for it.  I could bypass batteries altogether this way.  It would of course mean doubling my solar investment relative to my power requirements though.  It won't be a free ride.  I would start small as a proof of concept first and expand from there.
