I am running SLI'd XFX 8800 GT. While the top card idles about 56*c and the bottom is 52*c after applying Arctic Silver 5...just wondering if I can leave the cover off...the cover that you remove to get to the fan and heatsink fins...that has the XFX logo on it...and is held on by 7 tiny screws that once removed reveals the fins and stock fan. Is this ok to leave off and what purpose does it serve? Does it help the fan move air into the fins to cool it better and I should keep them on? Or its just mearly cosmetic?
If I'm looking at the correct card then it seems to *****move the air back out and away from the card*****
I would put the cover back on simply because...it was on before so there is probably a reason its up there
Hope this helps
