So i just built my system I5 2500k with a MSI GD55 mobo. haf 922 case 8 gigs ram. so im trying to learn to overclock and i want to know what the right voltage and the right temps are so i can make sure im not pushing to much and hurting my system. I got cpuz cpuz hardware monitor and Prime 95.

I got the clock up to 4.6 ghz at a 1.38 vot but 2 of my cores hit 68 and 69 C so i got worried should i back it down do i have to much volts or am i running ok
