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].
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.
PERFECTLY SEALED around EACH fan:
A look from the other side of the wall of fans:
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 (
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.
