I don't know much about those coolers, it looks quite effective. Also what thermal paste are you using? Depending on the quality of it, temps can change alot.

No thats a great cooler.

RealTemp is for 45nm processors yours is a 65nm, realtemp is going to be 10C low for you.

Speedfan always worked well for me on a 65nm conroe.

Looks like your temps overall are high, what thermal paste are you using and what method did you use to apply it? You may have used to much maybe the HSF isn't seated quite properly.

I guess I found my answer for my Tjunction max, 100C. http://www.overclock.net/intel-cpus/...etemp-0-a.html

That leaves me with CoreTemp being the correct temperature. I am not using Artic Silver, just some electrical grease. Would using Artic Silver actually lower my temperatures or is it just normal grease?

Also, how long should I run Prime95 to test for stability, as I think that 1.4v is probably not necessary, unless you think otherwise.

I can assure you that. Arctic Céramique dropped more than 10ºC on my old 4600+ versus zalmans default grease.

That doesn't mean you can take your CPU to to 100°C.

Anyways, Everest is incredible accurate. Go to majorgeeks.com to get it.

Arctic silver 5 is a really good thermal compound. Just be sure to apply the right amount. Their website shows you exactly how to do it.

Lol, that actually made me laugh. I know that I can't take it to 100C. At 95C it throttles then shuts down 100C, right? Well, I think I'll be looking to get some Artic Silver 5.

How long should I run Prime95 for stability. I want to lower the voltage from 1.4v, because I don't think I need that much, or maybe I do.

Those readings are odd, Coretemp and speedfan are well known, in my opinion I only trust those two to check my systems temp.

You should consider to get a better cooler. I'm adding Zalman 9700NT to the list 10acjed posted.

Incorrect.

A CPU has a reccomended Thermal threshhold. For the C2D series last I looked it was around 60-62c ( I cannot really remember ). Now if you are running 24/7 at above the Thermal threshhold then this will diminish the overall life of your CPU...Not kill it outright.

However stress testing and running above Thermal limits for a short period of time is acceptable as its only prolonged exposure to high voltage and temps that can cause damage to a CPU.

Its a common misconception I find. Heat will not outright kill a CPU at the lower ends of the Thermal threshold. Heat can cause damage and degrade the lifetime of your CPU but it wont outright blow it up unless exposed to temps way over its Thermal Threshold for a prolonged amount of time.

What can Outright kill a CPU is too much voltage as it simply burns it out internally.

CPU's haven't burned up since the AMD K7's.

The temp will get to 100 degree's and start dropping its multiplier and core voltage.

I agree with se7en56, Everest is awesome, and definitely a must have.

You temps seem normal, your chip has a thermal spec (temp you "should try and keep it under for extended periods") of 70 degree's C. Exceeding it by a little won't hurt it, just don't run it at 75 degree's for months on end.

EDIT:

Beat me to it!

It is 60 with the old chips, and the new revision's are 70.

Though I definitely think exceeding it would be alright for a bit. I have a Xeon x3220 that is exactly a q6600 in every way possible, only difference is that they are rated for a blistering 85 degree's.

Thank you for the clarifications everyone. That helped a lot. I will ask again lol.

How long should I run Prime95 for stability so I can start dropping my voltage?

I think 5 to 8 hours should be enough But if you want to really test it as a final stage, you should be running that for more than 12 hours.

Sorry about the incorrect info I gave back then, guess I didn't explain myself correctly. When I said "burn" I didn't mean that literally.
