i noticed a while ago that my 3750k reached 90C when i ran prime95 i was on stock cooler and it was kind of hot those days like 35 36C so i bought a new cpu cooler it was some generic brand but still beter than the stock cooler so i tried to test again i used intel extreme tuning utility because i heard that prime95 overvolts the cpu and my tems didnt go higher than 72C (it wasnt that hot like 24C) so is 72 high ? do i have to buy a better cooler ?
