i5-2500k @ 4.5 Ghz
Vcore: 1.3
idle: 30 celcius
100% load (folding@home) : 67 celcius
Ambient: 22-23 celcius
Cooler: Corsair H50, though I should note that I got about the same temps using a coolermaster Hyper 212 during the summer.
I have done testing with folding at home and while its load temps are more comparable to normal everyday load temps with real world apps, it is probably 7-10c lower then you would get running a stress tester application...
