depends on the paste... some paste turns to crap after long useage period.
someone on the steam forum a while ago was haveing reboot problems with his cpu, and it turned out his thermal paste was hard, cracked, and not doing its job at all, once he applied new paste, his system went i believe 15-20c cooler,
if you are haveing a heat problem with your computer and you dont overclock, odds are its a thermal paste issue, or you have a VERY poor cooler, and at least from my experiences, amd give you a pretty damn good cooler on higher end parts, and intel... i think its resomended to get a after market cooler, but i am not sure.
