I may have a prob with it, although I had to take it off in order to seseat my cpu, don't know what was wrong the first time. I just posted a message wondering if I messed up the thermal seal when I reapplied it with the same thermal paste. If I were to do it again, I would get a decent hsf from thermaltake, alpha, etc. and get some arctic silver and get the oem cpu. I don't overclock, but its nice to be safe. Plus, the retail hsf was a biotch to get on.
But, like I said I did reapply the hsf, so take my experience with a grain of salt.
