Just recieved my xfx 7850 (2gb) last night.
Md I got: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150609
W/ two fans. (is this the same model or did you buy one with only one fan)
Installed it an ran furmark (In windowed mode) Temps looked ok, but not a good test, will repeat in full screen (1920 x 1200).
I got the impression that the xfx brand seems to run hotter, Was planing on getting the His Ice, not sure why switched - lol.
