ASUS Motherboad Temperature

Asus P4c800-e deluxe motherboard
March 6, 2010 at 10:05:22
Specs: Windows XP
Hi,

I just installed a refurbished ASUS P4C800-E Deluxe motherboard (vers 2.0) and am running a P4-3GHz cpu on Windows XP, SP3. All my programs are running normally - no problems. However, my ASUS Probe indicates a motherboaard temperature of 65 C (constant without change) which seems very high. The Chassis Fan is shown as running at 2900 rpm (seemingly normal). The CPU temperature and fan rpm are running normal.

Is this motherboard temperature excessively high and if so, what could be the cause?

Many thanks,
George

So as to reliably read the CPU or any other temperature, go to BIOS. The software may be wrong.

No, the software is definitely correct (used for many years). In addition, I checked the BIOS reading and it's the same. However, I wonder if the chassis fan air flow could be reversed as a result of the lead connection possibly reversed when connected to the motherboard? Not sure if this is possible but will have to reopen the unit to check.

>>>Not sure if this is possible but will have to reopen the unit to check.<<<

So as to test the fan air flow, put a sheet of paper next to it, and see if it blows it away or sucks it in.

You should also clean the dust in the case, if any.

The air flow is OUT of the chassis (and quite strong). I assume that's the correct direction.

As for dust, I took care of that after removing all components and before replacing the motherboard. The unit is like new inside!

For whatever it's worth, the only airflow I have is the CPU fan (directly on top of the CPU), and chassis fan, mounted on the chassis immediately below the ATX power supply, and of course the fan within the poser supply itself. My recollection before I installed this motherboard is that the motherboard temperature as measured by the ASUS probe was significantly lower, maybe half. That's why I'm concerned and fear that over time, the components on the board may be damaged and fail.

"the software is definitely correct (used for many years)"

I thought this was a new/refurbed board? If you just installed it, there's no way you have used the software "for many years", at least not with that particular board. Try updating the BIOS. The latest non-beta is version 1023.

My original ASUS board (from 2004) failed this past January. I therefore ordered and installed this board, a fully operational board pulled from another unit that I've been calling in this thread a "refurbished" board. The ASUS PC Probe software, built into the board, was indeed used for years with my original motherboard and is of course the same on this refurbished board. Hope this clarifies things.

Back when the prescott processors first hit the market, many motherboard BIOS were rewritten to correct high or low temp reporting. Some motherboards over reported the prescott's already sky high temps and a few went under.

Like jam said, the very first thing to do is update the BIOS to the latest version. And take notes so you can refer to any differences.

Your case fan configuration should be good to go as long as there's a nice big hole in the lower front area for ambient air to get in.

Asus Probe is NOT built into the board. It's a software program that interfaces with the hardware sensors built into the board.

Are you 100% sure your "new" board is running the exact same BIOS as your old board? If not, I recommend you update your BIOS to version 1023...it's very possible that it will correct the temp reporting irregularities. I can just about guarantee that your board is NOT running at 65C.

Thank you Skip and Jam,

No, I'm not 100% sure that the BIOS version on the "new" board is the exact same as on my original board. Indeed, as you suggest, I'm beginning to suspect that the BIOS version is my temperature issue.

In fact, when I turn on the computer, the motherboard temperature IMMEDIATELY reads 65 degrees C - it doesn't slowly come up to that temperature as one would expect during an overheating scenario. And then, it stays fixed between 65 and 66 degrees with no movement up or down.

Furthermore, when I place my hand at the chassis fan exhaust, the air flow feels barely warm. Indeed, it feels only a little bit warmer than the ambient air temperature.

So tomorrow, I'll look into locating the latest BIOS version applicable to my ASUS motherboard (P4C800-E Deluxe). Once I've patched it, I'll get back to you with an update.

Thanks again,
George

Hi guys,

Having trouble locating the "ASUS Live Update" utility, needed to install the BIOS 1023 version... see below.

"P4C800-E Deluxe BIOS 1023
Using ASUSLiveUpdate to flash BIOS, you need to upgrade ASUSLiveupdate to v5.22.02 or later before flash BIOS."

So, although I downloaded the BIOS 1023 patch file, <p4ced23.zip>, I cannot proceed to install it without the Live Update utility and have not been able to locate it on the ASUS Download web site.

Help... any suggestions?

George

DON`T flash the BIOS within Windows.

Grab a USB stick and plug it into your PC.

Download the latest bios for your motherboard and unzip the .ROM file to the root of your USB stick.

Restart your PC, enter the BIOS, got to TOOLS-EZ-Flash, and if it is all working ok, you should see the contents of your USB stick listed.

(You can also do a backup of your original BIOS settings here, which will save you re-entering them all later )

Select the .ROM file, then follow the on screen instructions.

When it has finished, it will ask you to restart your PC.

At this point, it is a good idea (not essential), to power off completely and clear the CMOS, then power back up and re-enter all of your timings, voltages etc. (you only really need to do this step if you were having major problems before the BIOS flash.)

Hi guys,

MAJOR PROBLEM !!!!!

I downloaded the latest ASUS flash drive utility, <afudos223.zip> as well as the latest BIOS version applicable to my motherboard, P4C800-E Deluxe <p4ced23.zip>. I unzipped both files (afudos223.exe and p4ced23.rom> and placed the two files onto a cleanly formatted floppy boot disk having the autoexecbat and config.sys files.

I then rebooted into my clean floppy disk and proceeded with the flash procedure given by ASUS, i.e., at the A prompt, entering afudos /ip4ced23.rom. The procedure seemingly worked flawlessly without error. When prompted to reboot, and again at the A prompt, I removed the floppy and attempted to reboot, of course with the intent to re-enter the Setup program and reset the normal boot order. However, I was never able to get into the BIOS setup. The screen continuously presents me with the BIOS name and version, "American Megatrends, Version 1023" followed by a few other lines of info. But no matter how many times I hit the "Delete" key (or any other key), I cannot get beyond this screen. I've even tried placing the floppy disk into the drive but it seemingly bypasses the drive, always coming up to the American Megatrends screen.

Unfortunately, I do not have the old version (1010) of my BIOS and so, if it were possible, I could not revert back to it.

Now I really need HELP......

Thanks,
George

PROBLEM FIXED !!!!!

After not being able to proceed beyond the Am Megatrends screen with the last piece of info on the screen, "Device #02:". I interpreted this to mean that it was having trouble with one of the mass storage devices it was trying to AUTO detect. So I then pulled out all the USB connections, including my Western Digital 1 TB external hard drive (used only for storing backup images of my internal drives). Sure enough, as soon as I restarted the machine, I was able to get into my BIOS setup without any problem. Once there, in the Advanced screen, I changed the Legacy USB Support setting from AUTO to Disabled. This immediately fixed things and I was able to boot up normally without any problem.

So I now flashed my BIOS to Revision 1023 but sorry to say, it had NO impact on the temperature being read by the ASUS Probe. The motherboard still reads exactly as before this entire exercise, 65 to 66 degrees C. Therefore, should I now assume that it really isn't so and take my chances with the motherboard baking ?!?

In any case, I want to thank you guys for your personal time in trying to help me out.... I greatly appreciate it!

George

No, the motherboard feels perfectly normal. Upon someone else's suggestion, I took a can of "Dust-Of" spray and sprayed the Super I/O chip behind PC15 (location of the thermal sensor) and the immediate area around it on the motherboard. That too didn't move the temperature as measured by the ASUS Probe. Therefore, I've now concluded that the Probe is defective, probably as a result of a defective thermistor or diode. At least I have a valid temperature reading on the CPU. If that's normal, then I must assume all else is normal (I hope!).

Thanks!

Glad you found the problem and I hope you`ll fix it as soon as possible. The wrong reading shoudn`t make any problems, so why to bother ?
