The lower the better when it comes to the life of the cpu. My temp is 35c/95f load, and 25c/75f ambient. Idle its about 3-5f less. Thats with watercooling though. I had a Coolermaster Heatpipe sink, which ran 98f idle, 105f load. I wanted to get into water cooling though, especially with the ablity to add onto my existing system without adding more fans.

This is with my 1.2ghz tbird at 1.33ghz, 140fsb, 9.5x multi.

It can hit 1.42ghz, but is a bit unstable, and its not from the temp or voltage, which is 1.8v and can run 1.9v with no added bonus.
