OK, I have it installed.
The computer is in my garage, it's probably 85F in there. The card is in a Micro ATX case with two Arctic Cooling 120mm 900RPM fans, one intake, one exhaust.
The fan on the GPU is the loudest fan in my case. I couldn't hear my last card but I can hear this one. It's a muted whine at idle (37C is the idle temp.) On ramp up under load the fan is clearly audible. I wouldn't call it really loud but definitely noticeable. I wouldn't think this card would be something you would want if silence is what you're after.
I was under the impression that XFX lets a user change coolers, I believe I read that somewhere, but there are clearly two WARRANTY VOID IF REMOVED stickers over two of the screws. I didn't expect to see those so I will live with the cooling situation as it is because I don't want to void my warranty.
I haven't had a chance to overclock it yet, just not enough time but I'll do that as soon as I can.
Under load, while playing Secret World with everything on high at 1920x1200 the card peaks out at 63C
Ugh, this fan is clearly audible and it cycles up and down frequently which makes it definitely noticeable. I'm not happy with the sound levels at all. I can live with it in the garage but if it was in my office I wouldn't like it at all.
Going to try an OC it soon, performance is OK. Getting 25FPS in the above game at the above settings. I was hoping for a little better but OC will hopefully help.
