Lets Share Ideas of Ways to Manage Heat From Mining in a Home or Warehouse

[dmwardjr]

A look from the inside at the 48" wide rack.  The electrical will be in order soon.

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.

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. 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:

Switch for light in mining room; switch for fan in attic to exhaust heat out of attic; switch for 30" fan to exhaust heat at the ceiling into the attic; switch for intake fan in the attic to pull fresh air in to offset static pressure.

All pieces cut to size for GPU rig cases.  Now they need to be assembled...

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.

[dmwardjr]

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.

[dmwardjr]

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.

[dmwardjr]

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.

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

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....
