new hsf - high temps still

**Rex Mundi** · July 10th, 2004, 10:28 AM

Recently i got myself a Zalman CNPS7000A-Cu fan. I took out all the other fans and let the Zalman run in silent mode. Surprisingly, the idle temperature is still 50C and max usage temp 64C. This means it truely is a damn good fan and my pc is absolutely silent now

I could double the rotational speed of the fan to 2500 rpm, but what the heck that means only more noise and my computer seems to be doing fine.

Still im a bit uncertain about the case temperature sensor. Even when the case is open it says 40C! That just cant be right, because i put a themometer in there and its 30C tops.

Then i came across a thread somewhere, where this guy said that the Albatron 865PE PRO mainboard has sensors that measure temperatures a bit too high. I wonder if this is true...

PS i have a prescott processor and perform well up to temps of 70C. I suppose that is correct.

I have my Zalman running at 2,700 rpm without the Fanmate and it's still almost totally silent. You need to run the fan at full for a Prescott. What thermal paste did you use?

The manual of the fan didn't mention prescott specifically but did state that it would run in silent mode even for a 3GHz machine. As for the thermal paste, i used the stuff that came with it. It looks white. It is even so sticky, that when i accidentely put the fan on the p4 chip and i forgot about the fan header, that was still coiled around the fan, I took out the fan again, but ripped the processer with it. As a result some metallic pins were bend inderneath the processor chip. Luckily it was nothing serious, and i carefully placed the processor back into its socket. I correctly installed the fan afterwards and no damage was done. One thing is for sure. Im not going to try to remove that fan again

Anyways, i'll see how quiet normal mode is, but extreme cooling isn't what im after anyhow. Thanks for the tip

Sorry guys that i keep rambling on about this, but i need to know something. Is it possible that the high cpu temps are caused by the excessive heat dissipation from the power supply? Unfortunately my processor is very close to my power supply. These days its been very hot here with ambient temperatures above 30 degrees C. When i touch my power supply, i almost burn my fingers! It's that focking hot. For a 350W max output, is this normal? Anyways it explains why mbm tells me that the case temp is always above 40C! I have max fan speed with my zalman and in idle its 58C! lol

. Just shows how everything is relative on a hot day (33C). So anyways, are there 'cool' power supplys out there in the computer stores? Cause it sure would help keeping those temps down

Your power supply has only 1 fan I pressume? Most newer models have 2 fans, the one nearer the CPU sucks air in.
