8GH/s server/mining farm with 8kW aircon - btc currency

Hi,
As per my title I have a farm setup for mining that has four machines with 3x6990 cards in each one. That's a total of 12 cards and 24 gpus.

Temp in room is currently 23c which is maintaining a gpu temp on all cards of ~85c, one or two run abit hotter but no more than 90c, shutdown temp is 95 and I'm using cgminer on linuxcoin.

The side of the cases are using a custom engineered air flow delta fan setup. Each rig has 4x120mm 12v dc delta fans. Each fan is 192CFM (that's alot of air movement!) The fans on the cards themselves are operating at 80%. gpus are averaging about 345MH/s each and are stable. Going to tweak them abit more down the line....

I estimate about 6.5kW/h of power including the aircon :O Yes it costs a fortune to run!!!
That aircon unit has just been put in two days ago replacing a 3.5kW unit. See my other video which shows the outdoor unit.

Currently investigating ways to reduce cost, I'm looking at ways to generate my own electricity and to reuse the heat. Looking forward to winter when it's colder so my costs are reduced! Not often you hear someone saying there looking forward to winter :P

Thanks for the comment man. Stay tuned where I'll put up more videos showing people how to do stuff. Are you mining yourself?
