Recently about 2hours ago, I did an overclock with my fairly new CPU. About 2 weeks old, I decided to overclock to get the most performance out of my PC, so I did some researching, followed a tutorial online on how to manage to change clock speeds etc. So that's what I did, I thought jumping from 3.4Ghz to 4.5Ghz (3570k) was okay as I saw many people with similar spec PC's get the overclock without any problems. So after I ran the overclock, I restarted my PC, while browsing for more info, my comp froze for like 2 seconds and then went back to normal (got a bit worried). So I decided to download Prime95 and start the torture test. After running the torture test I was exceeding temperatures on most of my cores at over 90c!! (after 1hr20mins ish length) I was really worried, so I stopped the overclock and looked around if it that was normal because a lot of people were saying that ivy bridge chips get extremely hot. Right now I'm running idle with 4.5Ghz, at ~37c - is that too much? Were my prime95 temps too high? - by the way during the torture test, I got 0 errors. Do I need to re apply thermal paste? Should I lower the clockspeed to 4.2 or lower? Please help.. thanks!
