We've got a few K62 systems here at work. I recently upgraded one to a duron 800 on an ASUS A7S-VM board. I was looking at the old ASUS p5a board and k62 (a 475 I believe) and realized something.
I put some hs paste on it, smoothed it out real nice, and put on a lapped hsf unit. I pushed it down, and clamped it, then pulled it off and realized that the paste in the center of the cpu was pretty much untouched and left nothing on the hsf. Instead, there was a square ring of paste on the bottom of the hsf, with the center pretty much clean.
The hsf was lapped, so thats not the issue. But it makes me think that the aluminum heat spreader plate on the k62 (or atleast this one) is not very flat, but perhaps lower in the center. This ofcourse would not allow the center to contact the hsf as required.
I know k62's get pretty hot, and some can be decent oc'ers (had a 450 doing 550 no problem, and pretty cool last year), but I aslo hear of some people having lots of trouble with k62's. Perhaps this heat spreader is the problem...some may be fine, but others may be slightly deformed. I don't have any other k62's immediately available (a few currently in use at the moment) to look at.
I'm guessing you could lap the cpu, and I've heard that heat spreader doesn't pop off either, so don't try :)
Just thought I'd put this up incase you are running a k62 thats too hot and you have a decent hsf unit on it. Might want to check your paste imprint on the hsf, and if its bad, might want to give the cpu a few laps :)
