I'm afraid to go over 55c....
 
My load temperatures are 55c and the reason I haven't overclocked more is because I think above that might be too high... am I wrong?

Like what's your highest comfortable temps? (q6600)

What are you measuring the temps with? What are you using to load your CPU?

If I use the latest Prime95 to load the CPU and measure with Everest. Personally, I would start worrying if it went higher than 60C while running that test. But some people aren't bothered till closer to 70C. It depends on your willingness to push it I guess.

Everest shows two types of temp readings though. The individual core temps (Tjunction), and the CPU temp (Tcase). For a C2Q, Tjunction temps are always around 10 (+- 3) C higher than Tcase temps. Since Intel's thermal specification uses Tcase temps, and the max Tcase temp for a B3 stepping Q6600 is 62.2C, and 71C for the G0, I would start worrying when the CPU temp reaches 70C. Core temps can go as high as 80C for the G0.

Yeah, I was referring to Tjunction, thanks for clarifying that. Since I run FaH my load is at 100% 24/7, so that leads me to not want to push the temps up too high.

I use coretemp.exe

under 70*C should be ok

I've been running mine since release with a load of about 65c (B3@1.4v). I've noticed no instability or other issues because of it

egh I can hit 4.2Ghz @ 1.7v and still be safe at 70c

just keep pushing!

Do you feel comfortable pushing that amount of voltage even under water?
I imagine the chip won't last that long

55c = (aaa)

Why not? its still under the temp limit by Intel. so lets say that it cuts the life of the CPU in half or even 75% thats still 7-3.5 years. (assuming a 15 year life)

I will have that CPU sold by then end of the year I imagine. and the next person will probably keep it at stock clocks and get another few years out of it.

I plan on running it faster with more voltage with phase cooling later this year, I do currently have it @ 3.8Ghz with 1.4v but only because of temps, I would prefer with those volts (1.7) to keep the temps under 60c

IMHO if you are within all of Intel specs then you are fine. I am sure that they put safety margins in their CPU specs.

You will never in any application stress your CPU as much as Prime95, even when i am rendering with 100% CPU load its 10c cooler than prime.
