Intel Core 2 Quad Q6600 2.40GHz Socket 775 OEM Processor

Also, what software do you use to detect such temp? I am using Speedfan and CoreTemp. What do you use to stress test the system? Thanks again.

Perry,

I don’t have any specs on hand, but if I remember well, it will be stable at up to 70 C.

That’s the fans we bought:

The ASUS boards come with their own temp monitor. I actually only keep it running for about 48 hours upon setup with different renders to see how high it gets and I don’t bother after that. Many of the third party monitors don’t actually work with Vista 64 either.

Cheers,

Vince

Vincent,
Do you Overclock yours? I am able to do so up to 3.0GHz so far. After 4+ hrs of Stress test, Core0=56C, Core1=54, Core3=47 Core4=48. CoreVoltage = 1.2625V. (without OC, the temp is around 47C for the highest; I bought a Zalman Heatsink like yours) Going back to your original post on the temp, which software do you use to detect the temp? I use CoreTemp. If I use Speedfan, it reports similar to yours (20c). However, it is not accurate. There is a beta that deals with Quad CPU and after updating it, the reported temp is the same as CoreTemp. I realize you said ASUS has its own, but, I am not sure if the reporting mechanism is true for the Quad either. Would you mind trying CoreTemp and see what you get?

P.S.: TomHardware gave our Zalman a rating of 5 on cooling and failed on installation! Yes, it is awkward to install that fan. The holding clip touches one of the cooper pipe as well.

Yes, this particular one if overclocked to 3 GHz. It might go higher, but I wouldn’t recommnend it , you certainely don’t want to deal with any crashes if you can avoid it.

Again, the temp monitor we use comes with the ASUS board, I have not tried any other because most don’t work with Vista 64. I would hope that it is accurate since it is after all made specifically for that motherboard, but it does state CPU temperature, not separate “Cores”, that could be where the difference is. Unfortunately, Coretemp isn’t compatible with Vista 64 either.

I installed this heat sink in less than a minute, it was a perfect match on the Asus board, nothing like the silly plastic locking mount that comes with the Intel fan. In fact I was never able to get all of them to lock properly and the CPU overheated instantly causing a shutdown. I guess it just might depend on the motherboard.

I have XP64, not Vista 64. I have not upgraded yet and am contemplating the advantage of upgrade. Would most software survive in the 64 bit environment?

Thanks,

Vincent,
Just an quick update on my endevour to optimize my CPU. I was able to Overclock it to 3.2GHz with an idle Core temp of 36C (CPU temp = 28C). Fully loaded within 50C (4 cores). I think I can live with that. I stress test them with Orthos…

P.S.: the 20+C temp you are reporting is the CPU temp, not the core temp, add 10C to it is probably what your core runs. Which is still very good.

Thanks again for your help.
