Intel Core 2 Duo stock cooling solution

BPW · 05-26-2007, 07:17 AM

Hi all,

I just discovered that neat little tool called Intel thermal analysis tool. I ran that on my machine and the CPU temp on both cores went up to 70°C !

Idle temp is around 30-35°C, depending on ambient temp.

My Hardware:
DP965LT, E6700, Intel stock CPU cooler, 2 x 120mm case fans (plugged into mainboard).
BIOS settings are on aggressive and responsive settings for thermal control.

Is the temp actually supposed to go that high ??

The TAT is a pretty severe CPU stressor. I think its a better tool than Prime95 for C2D's.

The idea is to run it for a while and see if the system becomes unstable or locks up, which indicates a hardware issue.

I cant say how long you should run it for. With Prime95 I would have run it for minimum 15 hours, but running your CPU at those temps for that period of time doesnt seem right somehow.

Yeah, it's a pretty harsh test.
I got nowhere near these levels when running encoding applications, compilers and even games.

The default setting in TAT is 30 min. I'm wondering how long system builders run this test to "certify" their builds.

TAT is no joke for burning cpu's I don't like the stock Intel HSF's but 70C wouldn't surprise me even with a good third party solution. I would be scared to set it and walk away from it on any machine.

I left TAT on overnight to check stability of lower voltage/higher overclock. TAT will generally lock up in a minute or two if there is not enough juice (heck, seconds). Also the best way to checking cooling, I got temps down 15 degrees just by reapplying the TIM. Only thing it may not be good for is checking memory timings stability, but memtest is good for that.

I consider TAT solely a tool for testing cooling solutions. Which I believe is what Intel had in mind hence the "thermal" part. Not saying it can't give you a general idea in other areas.. I believe TAT was an in house utility that got leaked. It could definitely do some damage in the wrong hands. Even if thermal shutdown works fine either by CPU or MB, there can be a lot of life shortening burning in the meantime. If there is a utility that burns a C2D more I haven't seen it.

TAT is specifically designed to maximize thermal output from the chip - it actually goes beyond what any program could do to run the processor at full speed, so you'll never see these temperatures outside of using TAT (unless ambient is many degrees higher.)

TAT will crash an unstable CPU faster than anything else.
