Room temperature when I started was 13C in my basement when I started this test and went up to 14C when I ran the idle test. This is just slightly cooler than your room temperature of 60F (~15C ).

Using CoreTemp & Speedfan the temps under load went as high as 52C and then settled out at about 50C. Idle temp was reported as 20C.

The biggest difference between our setups is the heatsink and fan. Your Zalman 9700 significantly outperforms my Intel OEM heatsink and fan so your temps should be cooler than this and they are. If my computer was operated at your room temperature then my load temp would probably be about 53C. Your load temp of about 47C with a much better cooler makes perfect sense.

Anandtech did a review of the Zalman 9700. On an X6800 at 2.93 GHz their load temp dropped by 20C from 56C to 36C and their Idle temp went from 41C to 28C. Knowing this, it's possible that after you properly apply some AS5 and give it time to setup, your CoreTemp readings might even decrease a few degrees.

While experimenting I've seen CoreTemp readings of 80C at which point the Intel C2D thermal throttling kicked in to keep the temps from hitting the Intel maximum of 85C. I have no doubt that CoreTemp is reporting the correct temperature on my P5B Deluxe.

I'm also convinced that on your board CoreTemp and the new version of SpeedFan are reporting your real core temperature. The Intel TAT program is reporting about 3C less at full load on my board but seems to be out to lunch on your board. If I was you, I'd be trusting CoreTemp.





NOTE: Orthos, CoreTemp and TAT are all reporting 3376 MHz because they're incorrectly reading the multiplier. It knows it is an E6400 so these programs assume that I am running at 8 X 422 MHz = 3376 MHz when I'm actually running at 7 X 422 MHz = 2954 MHz.
this post was taken from hard. someone tested this for me... interesting. now i'm really confused which to beleive
