My case is at 19 degrees Celcius and my CPU is at 18.

My temp probes are good because theyve always displayed accurate information. I just opened my window next to my computer and the temp dropped like a rock. I'm using a Thermaltake Beetle running at medium speed and a poly-synthetic thermal compound. My CPU is even overclocked from 2 Ghz to 2.4 and it's still staying that cold. Is this normal?

Hi Sp1key
Are you reading the Probes that are built into your mobo or some you have attached your self.
The only way I can account for the reading .is that your cpu probe as come off and is reading the case temp in a lower position than your case probe.There is no way with air or water cooling your CPU temp can be less than the ambient temp of you case.If you are getting the readings via the mobo it could be a software fault,have you checked them in your Bios.
Good luck and merry Christmas

The probes came built-in to the motherboard. I am pretty sure that the CPU probe is still attached because I stressed the CPU and the CPU temp rose to about 44C but the case temp stayed at 29, like it was before I stressed it. I'm not that experienced with computer temperature but that just seemed weird to me. The Bios displays the same readings as PCAlert also. I was thinking about flashing the Bios but the upgrades are negligible and I'm worried about any problems that might occur after flashing.

Check your bios for actual temps

There is no way those temperatures are accurate--even in a refigerator, the CPU would be hotter than that.

 

[Sp1key]

I checked the Bios at startup and the temps read like this:

System: 24C
CPU: 26C

The temps are still pretty close, and this was at boot with an overclocked CPU. I don't even have cool and quiet enabled. Is it possible that some of the thermal paste could have gotten on the probe itself? I'm not that great at applying that stuff.

The temp sensors on the board are very cheap items. Because of this, they are not the most accurate of devices. Yours just read low.

BTW do not flash a bios unless the update has a feature you need or corrects a problem you have.

26C at boot up is a believable temp for an amd64; 18C is not.

 

[Sp1key]

Alright, thank you for the replys.

I have an AMD 64 X2. The 18C was not at boot-up, it was after my computer had been on for about a day and I opened the window next to it to let some cold air in. I was just shocked when I saw that temperature and wanted some clarification.

Remember that a "real" and accurate temperature meter would cost as much as the whole motherboard itself.

A 10°C variance in on-board sensors is not unusual or unexpected, and as above the sensors are just a 20 cent component that is uncalibrated.

Treat any voltage or temperature readings obtained as a rough guide only, when using on-board sensors. The issue just gets worse when using third party software to "interpret" the sensors.

26C at boot up is a believable temp for an amd64; 18C is not.

If anyone can figure out how to get an AMD 64x2 to idle at 18 degrees, they are going to make a lot of money!

18C CPU is normal if your PC is sitting out on the back porch at your house in Alaska.

Mine usually idles at about 40 degrees and that's with water cooling--although its a piece of crap Pentium D, 830. Those original dual core pentiums ran (run) way too hot! :down: I was forced to install a water cooled system because it would run up to the high 60s low 70s under heavy load (primarily video editing). With water cooling, it never goes above the mid 50s. The AMD dual cores run much cooler. Not sure about the new Pentium core duos.

Mulder the 9xx series [last before the c2d] actually run pretty cool. They use EIST and xp has native support for eist [win2k does not] When I boot into xp, it runs at around 30-32C; same hardware under win2k and it runs at about 40-45C. Not too bad for a P4D.
