hmm kinda... when you are overclocking a processor, especially the wolfdales, the vcore is really what 'kills' the processor - not so much the actual heat. i have mine @ 4.3 and it runs around 53 degrees on full load max fpu stress in prime 95 and thats the max temp i run it at. i personally dont like it running at 60 degrees or high but thats just ME. if memory serves correct the E8500 can run at 70-75 C and remain within limits of operation. btw max vcore is 1.36 so keep it within that if you plan on keeping it for awhile.
