Re: 8800 GTX temps
According to Nvidia it's fine, but I doubt most enthusiasts consider 84C fine. I too keep my fan @ 100% to maintain load temps ~72c.
I really can't stand my video card idling higher than my overclocked C2D under load so my waterblock will be here by the end of the week. My CPU temps went up a couple degress when I swapped out my GTS for a GTX. It's like having a furnace sitting just under my CPU. My GTS idled at ~43c and I've never seen the GTX idle below 56c. I had no need to add the GTS to my watercooling loop because the temps were reasonable, but GTX temps aren't.
