Topic: Suggest best Airflow design (Read 514 times)
I understand your pain. I had the same problem mining bitcoin. I ended up making a large enclosure to house all of my miners. I then put the A/C I wanted to use in my boys room and cut out a 200 square inch by 6 inch deep piece of evaporative cooling panel and used my antminer s9's strong fans to pull air out of the enclosure. I tell no lie, I swear. We recently had 2 115 degree days and my miners where around 194. Where I live has very low humidity in summer and the only things I have had trouble with are the stupid bitmain 1600w PSU's which are just plain dumb and don't last 12 months.
Respect Man, respect. Love your current setup.
So I have settled on a design for my rigs and started to build a small piece of it. I am limited on space and amps(growth). Reading the forums I know alot of home users will use their garage for an open air flow design but I dont think they have kids lol. My kids are always playing and I am always cleaning dust, dirt and spiders out of my garage. I have a small room in my basement that I built as a bedroom years ago when I decided to finish my unfinished basement. The room is roughly 12 x 12 with the added benefit of a storm window that is roughly 22 in wide x 48 in tall.
With what I have now I tried to build out a box type setup with foam board surrounding the rack but the 2 window fans I have only do 400CFM max each and it just wasn't enough. I just ordered a 2400 CFM fan on amazon https://www.amazon.com/gp/product/B002AGZUMA/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1 which should fit my 22in window with minimal cutting on the fan unit. The idea I have now is to mirror the rack on the left with another on the right. I will have the middle shelf and the bottom shelf on both sides will 4 rigs each. Once done this should give me a total of 16 rigs with 220 that should roughly pull 96 amps from my 200 amp breaker box. Just need to make sure I don't turn on the Stove, dryer and ac at the same time lol. Its really pushing it so I might not build 16 rigs to be cautious but we will see. The idea I have now is to install 2 x 2400 cfm fans in the storm window and have 4 box fans on each shelf forcing air to the middle isle. Then I can build out a box type foam board setup around both racks and have a door to the middle isle with 3 fans on it pushing air to the storm window. This is the only way I can see building a cold/hot isle system with the room I have to work with.
Would love some thoughts and suggestions!
Happy mining all!
