Asus Board Monitor Temps

[Autolectrician]

I just got my h2o system up and running on a new a7a266 asus board. And installed a temp probe next to the cpu core but when i compare the temps in the asus monitor they are 20 degrees higher than my probe temps. I have read about the asus temps being 10+ higher but it is over 20+ higher is anyone familiar with this board and can give me an idea if they are even close.
AMBIENT TEMP =74.7/23.6
SUMP WATER TEMP =76.8/24.8
MY PROBE CPU TEMP =88.5/31
ASUS CPU PROBE TEMP =120/48
That is a big spread for temps i reseated heat sink 3 times but with the same results.
any help would be welcome. THANKS

You might want to check in motherboard monitor, too, they give the same temps as the VIA monitor some boards come with, and so might be more accurate than the infamous AsusProbe

The ASUS Probe is famous for reporting temps up to 10C higher than the actual temp maybe you should try using programs like MBM5

P.S I RECOMMEND YOU TO USE VCOOL (CPU Cooling Program) u gotta love it when u've tried it!!!!!

I also have an a7a266 and have had no major problems with it so far. Its cpu temp monitoring is far from accurate however. I've tried many different programs and get the same number on all of them. AsusProbe only reports what the mobo says and is not the problem. The real problem is the positioning of the temp sensor on the motherboard. I haven't personally checked but have read other threads where changing the air flow of the case changes the probe temp but not the actual cpu temp. The fact that with your setup the air movement in your case (esp around the cpu) may be significantly less than an air cooled setup could be affecting things.

I personally have an aircooled setup and the mobo is about 2-4 deg C off of what a temp sensor mounted next to the die says. The best way I've found for coping with the situation is using MBM5 and setting an offset of the avg difference between the mobo and your sensor. It's not a perfect solution but it's been fairly accurate for me so far. The bottomline for anyone with an AMD processor is trust a temp sensor mounted by the die as it will always be more accurate than the one mounted on the mobo.

We'll see what happens when I switch to watercooling in a couple days.

Try at least 3 different programs. Believe whichever ones agree with each other.

I also have an A7A266. The temps it was spouting were, in essence, utter crap. I ended up deducting about 10 degrees C from the core temps it was saying. The method is pretty simple. Turn your PC on from stone cold. ie. aint been used in hours. Time how long it takes to get from pressing the power button to getting into the BIOS and the hardware monitoring page, and record the mobo and CPU temps.

On my machine it takes about 15 seconds to get to that page, by which time the CPU had a temperature of 12 degrees higher than my mobo. So, allowing for some heating, I just deducted 10 degrees from whatever MBM5 tells me.

It aint scientific, or accurate, or safe probably, but I don't care.

Thanks for the ideas! I took a radio shack thermometer apart and made 2 probes set 1 under the heat sink up against the core and 1 under the core and when i average them out they come real close to what asus probe says. I thought that was interesting so i took a nurses infered thermometer and checked temps at the center of the heat sink and they matched so i am going to asume my probe next to the die is correct could not believe underside temps!!! under load 157f and 1/8" away the asus probe 127f puzzling I think i might try to stretch it closer. anyway thanks for the help.
