Currently at 42C with 22C ambient. (full load running two Folding clients)
Take note that this is with a NB and GPU block in the loop as well...
I tried going higher but I don't want to go above 1.65Vcore. At 3.64Ghz 260FSB Prime95 becomes unstable, one of the clients drops out. And if I leave it at that speed I sometimes find a black screen and locked up system overnight. 257FSB is rock solid though, I even run Partitionmagic, DriveImage etc. at that speed! What's the sense in having a great OC but having to revert back down everytime you need to work on your setup anyways?
