Just wanted to give everyone a heads up on one of our rigs finally hit 6 months in
Just a sample of pictures of 12 cards all with liquid cooling and passive custom heatsinks i built for the dc powersupply side of the card. All ram has custom aluminum heatsinks.
Each 8gb RX 580 is clocked at 1400mhz gpu 2200 ram I-9 on new claymore produces 370-385h/z
all cards are liquid cooled with outdoor pump and 2000 gallon tank. Even when it was 120 outside this summer in Vegas card gpu temps were 69-74 degree C pretty cool just using a bulk water tank and 1/4hp water pump.
No cards have fans all passive cooling for the card and active cooling on the gpu with custom made water blocks for high flow.
Of course the whole system is powered with 1600 watt custom 240v powersupplies with 16 x 8 pin connectors 12 x 4 pin connectors really a great PS 90 platinum rated was def the way to go total system size is 200 gpus on my 400 amp service panel which was the biggest i could put on my property.
