I almost cracked the core of a p3 500. The damn intel heatsink had one of the most uncoperative clips I've ever seen. I've since switched heatsinks on that cpu and when I took off the intel one, there was noticable damage on side of the core. Thankfully it's chugged along just fine ever since in a family members pc.
Maybe tomorrow I'll wanna settle down, until tomorrow I'll just keep moving on...
