I have just build new rig with HIS 6850, ASRock 870 Extreme 3, and 1090T. When I play latest COD (Black Ops) all at maximum it runs fine, same for all Half life games and Portal (all I have played with new PC thus far). But if I play COD MW2, all at max the GPU heats up to 90C with fan at 100%. Same for Red Alert. There is no reason why it sould run 90C/100% on those "older" games when my old 9800GTX pulled it off just fine with no overheating. Yes, I have the latest drivers. Thoughts?
