Passive cooling on cards?!
Huh?
Mine are not passive cooled, simply sapphire r9 280x "dual-x" cards. I have to run the fans at 100% to keep them at ~75c at 1080/1500 I13. I plan on burning the fans out, because they will at 100%, and replacing with watercooling. Lots of the non-ref 280x cards are the same non-ref design, kinda hoping someone comes out with a new block, against all odds.
Nice one, how much watt those cards consume?
Bought a Asus R9 280X DCII, it is huge and the coolest card available..
I'm confused by what you are saying here. You were able to mine on a DCII with fan speed at idle? I find that exceptionally hard to believe. Regardless, I bought this card to watercool. It makes absolutely no sense to buy a custom non-refrence cooler just to take it off and throw it away.
Two of those ridiculously huge cards wouldn't even fit in my case anyway, and they'd never fit in a quadfire setup like my 4x7970 rig. I'd avoid buying those for mining on that reason alone.
