Too much ?

[stymie222]

I have a Pent 4 3.2GHZ Processor. I used Artic Ice on the CPU. My Lian-Li case has a tube and fan that delivers fresh air to the CPU. I clean the case, fans and filters often. While copying DVD material I am right at the temperature threshold, 156 deg F. My Intel temperture monitoring alert comes on warning me of the high temps. This max temp will go on for about 10 minutes while the DVD program/ copying process completes its task. The max temp does not seem to go beyond 158 F. Am I doing any damage ? Is there anything any of us can do to bring down CPU temps without buying add-on coolers? Is Intel giving us the right size cooling fans for their processors ?

If the P4 is anything but a Williamette, you've got a problem. Williamettes run hot. If it's any other core, that's a problem.

As far as I know.

It is a little high. 68c

What exact processor model?

What lian li case?

Are you sure the heatsink is properly clamped down? If your on lga 775, those pins MUST be all the way through the motherboard.

Intel Pent 4 640 Prescott Lga775, Lian-Li PC-6070A Plus Case Everything seated properly, usually running at 104 Deg. F on normal tasking. Will only heat up downloding movies from Internet and tasks listed above on first post. Does not heat up playing PC games

I see no issues with case airflow as long as that rear fan with the duct is on exaust.

This seriously leads to only 2 things, too much dust in the heatsink, or a bad mount.

I would CAREFULLY try to reach into the case and touch the side of the heatsink. Is it warm? cold? hot?

The LGA775 heatsink is difficult to install properly if you have the motherboard already installed in the case. I'd pull the motherboard out and reinstall the heatsink per these instructions (http://www.hardwarezone.com/guides/intel-socketT/?pg=6).

Would it be possible for the INTEL fan on the CPU while operating fine accross slow and medium speeds, not to operate at its full speed ,causing overheating? I was thinking about installing a Zalman CPU cooler. Their model CNPS9500At looks good for my INTEL motherboard [ D955XBK ]. Has anyone installed this unit? I would appreciate any comments.

Depending on how much AC 5 you used will determine the cooling of the CPU. If you used more than a dot the size of a grain of rice, the AC 5 could be acting as an insulator between the CPU and HSU.

Like others have said, the LGA 775 stock coolers are very difficult to get on properly. I would remount the CPU Cooler to rule out that possibility if what I say below isn't the problem. A lot of motherboards have an auto fan control feature in the bios somewhere. On my Asus board, I believe that it is called Q(uiet)-control. It runs the CPU fan speed accordingly to keep it at x degrees. Be sure that is turned OFF. A quick way to tell if that is on or not is your CPU Fan Rpm. My stock intel (Pentium 4 630, 3.0 Ghz) cooler runs at about 2700 rpm. Also, if you have a really strong fan like a vantec tornado on that fresh air intake, could be causing the problem, although I doubt it.

EDIT: You probably know this, but just in case, Intel CPU's come with a cooler that has a thermal pad on it. If you did not remove the pad, and put Arctic Silver 5 on your processor, that may be the source of your problem.
