Great. So how can you tell how a cooling fan has failed? The trail of black smoke from the back of the PC?
I forgot to mention that it was designed to be a passive cooler, no fan required

He doesn't seem to work quite as well under a long, heavy load. The temps will get up to 50-51C occasionally (51C being the highest I've seen), but that acceptable to me. Then you can close the game, pop up the temp monitor and watch the temp drop 8C in about 10 sec

Only kidding, sounds like a great rig... but I'm not going 64 bit for a couple of years yet. Waiting for Xfire to mature and M2 to get released... and of course, saving the peniies to pay for it.
I know the feeling, but I decided to go ahead and jump in since my old comp had gone 3 years without being touched. Dunno if I'd go for M2 though, I kinda get the feeling that AMD is going to skip to DDR3 pretty quickly. Bet then, there's always something better just around the corner. *shrug*
