Running an i5 2500K with an Asus P8Z68V-Pro/Gen 3 motherboard cooled with a Thermalright Ultra 120 heatsink attached to a 120mm fan. Right now I have the CPU at 4GHZ @ 1.24V. Prime95 stress testing hovers around 48C and Intel Burn test hovers around 55C. I played around last night and I ran it at 4.5GHZ @ 1.3V. Prime95 temps were mid 60s and Intel Burn Test was high 70s with a few quick peaks in the low 80s. I played some games at this voltage/speed and actual usage temps were still really low (high 40s, it didn't even crack 50C). 100% stability in all cases. My question is what are the max temps I ought to run this thing at? I have a feeling I could push it to 4.7 - 4.8 but I don't want to roast my chip. Thanks.
