Been swapping some video cards around for kicks. I got a brand new Powercolor 7870 2gb Tahiti EZ (this one) and put it in my machine.
Nothing currently overclocked, just running bitcoin mining on it to test it out. It's currently sitting at 975mhz (stock boost mode), but 90 degrees with the fan kicked up to 80+%!
I tried the bios update here (http://hardforum.com/showthread.php?t=1750373) to go from the 031 to 032. Not any better, although it does actually go to 975 mhz now. Before it wasn't boosting.
Before this, in the same case and everything, I had a 7870 2gb card from Gigabyte with 3 fans on it, plus a 7850 xfx dual-fan card in crossfire (and no empty slots between them). Running mining on both, and the 7850 OC'd, temps stayed under 75 on both cards.
Is something wrong with the new Tahiti card, or is the single fan really that bad at cooling? My case has minimal airflow, but that's never been a problem before (as said above, even with dual cards). There's no other fans than on the CPU, GPU, and PSU, but the entire top of the case is mesh so heat rises out pretty easily without needing extra exhaust.
