Hmm i've been reading that the tuniq tower 120 fan is really loud although I don't hear anything from mine and its on high...it's going full speed according to the mobo fan monitor.

The fan seems rather quiet to me at full speed and it is still an excellent hsf for being two years old.

There is a lengthy thread over at xtremesystems about the new G0 stepping q6600 that discusses high load temp readings and many people are suspecting that coretemp and TAT are misreading the temps on the new G0 q6600's. You wouldn't happen to have a G0 stepping q6600 would you? They are speculating that perhaps speedfan is reading proper temps.

Just got my new memory in today and overclocked to 3312mhz with a 368 FSB and 9X multiplyer. Memory is at 920mhz with a 1.25 modifier. Cpu at idle stays around 41c and has load temps into the high 40's. Vcore is at 1.3325V. Memory is at default 2.2v and remains at default 4,4,4,12 timings. I suppose I could push for more if I increased voltages, or relaxed memory timings or reduced the memory modifier. I assume the gains will be minimal. Perhaps I will try, perhaps not. So far 100% stable at these settings. Video card is at 630/1000.

3.3Ghz is a pretty good overclock. and 4-4-4-12 timings at 920Mhz is also very good. I'd be happy with what you have. Chances are the further gains wouldn't be that noticeable anyways.

Hi sloth151 - welcome!

The memory speed and timings do sound good. Maybe we need to talk to Patriot about checking out some of their stuff! Grin

Hi all,

I am back again. Now I changed my q6600b3 to a q6600G0. I havent done so much overclocking yet - just plugged it in and clocked it to run at 3 GHz, just as my old CPU.

With coretemp I recognised temperatures up about 72c on my B3, where my new G0 come close to 65c. Both temps are read from the coretemp logfile, after a Futuremark 2006 test. The biggest thing here is that my voltage has falled from +1.3v og 1.1v - both measured on 3 GHz.

A q6600@3.3GHz running loaded, measureing a temperature below 50c seems to be magic for me. What have you done to get is so low?

qwwwizx,
My temps seem to hover in the high 50's and low 60's at 3.3Ghz. The low temps I was mentioning earlier were based on running the folding@home SMP client @ 3.0Ghz. I have since learned that folding@home does not load the cpu as much as four instances of Prime95. I suspect that if sloth151 tried 4 instances of prime95 (or two instances or Orthos) he would experience the same issue.

All my temperatures were based on the assumption that %100 load with folding@home was the same as %100 load with prime 95. It's not, there is a huge difference in temps (approx. 15c) when running 4 instances of prime95. I used Prime95 to test stability for about 10hrs. and haven't used it since. I also have not come across another program that can load the cpu that heavily and my everyday loaded temps rarely see anything above 62c that is usually only when I fire up WoW and keep folding@home running in the background.

Another thing that doesn't hurt is my ambient room temps rarely get warmer than 70f

I originally suggested that you should try to keep temps below 60c if possible. After reading quite a bit on other forums about the q6600's I think you would be perfectly safe with loaded temps around 65c.
