I can't tell you how many people I've seen freaking out at PII temps in the 60s. I have no idea where they get their info, but IIRC the max temp on the Athlon X2's up to the PII's has always been about 75C. I've built probably 20 Athlon IIs, Phenom II X2's unlocked, and PII X4s - EVERY ONE OF THEM ran in the low to mid 60s with the stock HSF when under 100% load, regardless of whether they were unlocked, overclocked, undervolting (which, honestly, does bring it down to high 50s) or whatever. Heck, the i7 920 on the stock HSF runs at 70C when under P95. I have an Arctic Cooling FP7 on it (which, I think, isn't that great) overclocked to 3.66GHz and it's still at 71-72C under full load. Based on the 200-250 PCs I've built over the past 6-7 years, I'd say 70C under full load for ANY Intel/AMD processor is about normal with the stock HSF. And, I've yet to see any of those 200-250 processors fail. I build PCs as a hobby and sell them to friends, family, local businesses and on eBay whenever I'm bored and I've never heard from any of them that their PC broke for any reason.
