thats why i want to overclock higher to 1000 or 1100 core.
1100 core.
what
Take a temp gun & point it at the vrm, it will be scorching hot, for your money's sake I hope you don't do that.
It wont be worth the miniscule increase in hashing rate & jump in power usage.
Really, one of the worst ideas is to overvolt and 30% OC a dual gpu card
my gpu temprature and the air in the mining rig box is very cold... i have a 6000rpm 120mm fan that pushes cold air from outside at 260CFM in a exhaust right on top of the 2x 6990 (will take a picture later)... its very loud and extremely powerful, is not im my room or near my room so noise and heat is not my problem...
