Hi

I'll repaired my garage sound proof and water tight. I have had an electrician come round and make sure the correct cabling are used 20amp cables and new fuse board all safe. Power networks has upgrade the fuse and electricity board.

I need to punch a hole in the wall to vent the heat. I would like to fit up to 6 miners. But I would like to know if this plan would work
https://ibb.co/YcTn5gY

Do I need to push all the heat (ebay 3-d printed vents) to one side which is divided in the middle. I was thinking 3 high 2 rows. With an extractor fan built into the enclosure and 8" thermally insulated ducting to the outside.

I've contacted a company who specialised in fans to suggest what extractor fan would be necessary. Think suggestions here were something that would do 4,000 CFM or 5,000cfm.

Any advice on build would be fantastic -

Would my design be over the top. Could I just do a large box with an extra fan like this

Your plan according to the image is fine the important is you can bring the hot air out from the room to avoid temperature issues.

I think about the exhaust fan 5,000 CFM is the right choice.

About the video, you can follow the design if you'd like it just make sure that you can exhaust hot air from the box and filter the intake air.

Do you have a window? I have run a few different setups using my garage with neighbors in fairly close proximity. One was using my window as the direct exhaust.

The bottom of the window provides air intake along with a few other spots. I ultimately went to a system using my garage door propped open and secured along with thick wire mesh for security. Exhaust through the middle and intake on either side.

The best advice I have is do it for as little cost as possible.   Here is the topic I document my summer setup as it ran last year.

Thanks for your advice. I was thinking it might be better to have a large box enclosure as then when the computers change size I don't have to worry about aligning up the holes for the hot and cool aisle.

So if I position them in rows of 2 or 3 and have a 5,000 cfm extractor fan above sucking out the heat to the outside. With passive air filters in the bottom. What position shall I put the computers facing heat towards centre? in rows of 2  or 3 high? Does it matter? the ducting should be 8" thermal insulated ?

changed to a bit more simple: https://ibb.co/BNGPCfJ

Last thing. The fans; suppliers are asking about pressure? I said I need 5,000 cfm and they generally want to know pressure too?



Due to the changing size of the Antminers. Would this design work? A 5,000 cfm fan at the top with 2 passive filter air intakes at the bottom of each side.

Am I getting close? Lol.

what country are you in?

2 of these will do

https://www.homedepot.com/p/QuietCool-Professional-3013-CFM-Power-Gable-Mount-Attic-Fan-AFG-PRO-3-0/206047381

set thermostats 5 to 10 degrees different.

only one will run when it is cooler two when warmer

lastly you will have one working if one breaks which will allow you to run at least ½ your gear.

I’m in the U.K. struggling with fan options.

Does the design work? I’ve left space between units

It should be good for 6 units max.

We are talk s17pro or something like that correct?

I will poke around on uk websites to see if I can find some good fans for you.

this is too weak https://www.amazon.co.uk/220-240V-Pressure-Adjustable-Controller-Warehouse/dp/B083DXZTLC

nice fan for 2 units tops



This one below may not be in stock

https://www.amazon.co.uk/Extractor-Ducting-Kitchen-Restaurant-Industrial/dp/B07KFLTNXF

this has a 20 inch size



ebay uk has a few from the usa

this one is cheap   but you will need two or three of them.

https://www.ebay.co.uk/itm/NOS-ATTIC-AIRE-GV-15-Electric-Attic-Exhaust-Fan-Vent-Hot-Air-Ventilator/264492063117



found a beast  2 speeds  more then enough 7800 cfm and 5400 cfm

https://www.ebay.co.uk/itm/Cool-Attic-Whole-House-Exhaust-Fan-w-Shutter-2-Speed-Belt-Drive-30in-CX30BD2SPD/392442242828?

this is a nice fan  more then you need. and a bit pricey.



this one is nice

https://www.ebay.co.uk/itm/Whole-House-Fan-24in-Shutter-Belt-Drive-Air-Vent-Attic-2-Speed-4600-CFM-1-3-HP/273235591260?

2 speeds



this is similar

https://www.ebay.co.uk/itm/Whole-House-Fan-Shutter-24-Inches-Direct-Drive-Powder-Coated-Weather-Resistant/302792237883?

2 speeds



or get 2 of these

About the static pressure, high pressure is always recommended to move the hot air fast on the room

Better understand airflows in the room you can use smoke to check how air flows in the room work.

I don't know the exact pressure since I don't know how large the room is but if you are going to build a large box enclosure I think 0.5 pressure might be enough to vent the hot air from the box. Just always remember "the higher, the better"

nope.

do not shrink the ducts .

Ie if miner fans are 120mm

ducts should be bigger then 120mm

shrinking ducts and making ducts longer impend air flow. which = bad not good.

So go to 6” ducts 150mm. If I change the 4” to 6”. Will it be poss to have them both go to a 6” duct and out through 6” hole?

Otherwise this was another idea.



Passive air filter at the bottom on the floor of enclosure.

Inline fan should be all hidden inside.

not likely.

the same size or bigger .

2 x 6 inch  is pie x r squared.

so a six inch hole is 3.14 x 9 or about 28 square inches.    you have 2 of them so when they feed into 1  it needs to be about 2 x 28 = 56  round up to 60 square inches.

that is a duct about 9 inches as   3.14 x 4.5 x 4.5 = 63 square inches.   so a 9 inch at smallest but a 10 inch is better.

So the fans required at 24" 600mm 60cm. I can fit that on the enclosure but how do I vent that out of a garage? I can't stick a 30" hole in the wall?

How about building a stud wall to section off a third of the garage; which would be about a 1.5 meters 1.8 high.

Copy this guy

https://www.youtube.com/watch?v=ueZqBXAKM_w

So UPVC 4" goes into 6" duct with 1250cfm removing heat. It worked for him.



I’ve got the stud wall being built on Tuesday... I will prob have 6 S17 pro. Although new Antminer are due any month...



Help! I need a U.K. fan that will fit an 8” surely a 1250 cfm would cover pro 73th/s?
