Hello, i just have build up my system. HWMonitor shows that my motherboards temp is 115C. Im getting crazy about it but cant understand how it can be so high when my system is on idle. Do u know what can be wrong? Is it bad sensor on my new motherboard asus h81m-plus?

PS. I havent updated BIOS yet, may it be the reason why?
Also other components seems to be good cpu idle 26C.

I would try updating the BIOS. Also install any ASUS utility that is available from ASUS for HW monitoring, check the download/support page for this model. Sometimes the third-party utilities aren't calibrated correctly for a circuit.

well, i dont think its a good idea to update just becaus its quite new version, also i have downloaded other programs to check so it was obviously what u say, that monitor showed faulty. On idle i get 28C checked with 3 different programs, so i can sleep well ^^

Which sensor is it? Some are just way off. This is normal. As long as your core temps are fine, I wouldn't worry about the rest.

I've seen it happen, where there's a BIOS bug that causes oddball readings, and the BIOS upgrade solves the problem.

When I buy a motherboard, this is a factor that keeps me shopping longer. Sometimes, an initial release has a great BIOS version, and you STILL find it useful to update it. From there it could go through another 5 or ten revisions, and you might decide not to update further.

There's the other possibility that you can wait, monitor some forums, see if the board is being issued with BIOS fixes that resolve early reported problems.

ehh have updated bios to latest version, same problem....
Also this medieval asus prome ii doesnt support windows 8.1.
But also the other programs show 28C and never change even when i stress cpu (it should at least change for some degrees... so i also wonder if they read the tempreture, so confused...
Does anyone know how can i exactly check if the problem in HWmonitor or sensor on motherboard?

CPUID shows your Pentium is idling at 38, which is a bit warm for idle. A max temp of 53 is nothing to worry about however.

I assume you have other fans in your case, just not plugged into your board. As I said above, that sensor can be off. Not a big deal. If it were correct, you would feel a huge amount of heat coming off the board, more than off the CPU, which is most certainly not the case.

Idle is 27C, this picture was done on stress test that why is 53. But as i said it doesn't matter if it idle or load motherboard temperatures are the same
I really have no idea, couldnt find anyone who had the same problem with this board.

It could be a vrm temperature sensor especially if you oc you'll put more stress on the vrm's and those vrm's feature no cooling.

there have been a number of reports of the Asus AI Suite III causing conflicts in the board's BIOS. I had a similiar problem but the exact opposite in that it would never read temps over 67C in AI Suite III performance monitor utiity. then i happened to download RealTemp and it showed 99-100C. Then INTEL's XTU showed the same temps with constant thermal throttling.

There was also a conflict with the "Probe II Sense" driver, which is the temp sensor, which installed as part of AI suite III.

Try un-installing AI Suite III, then after un-installing, asus has a AI Suite III cleaner, which you need to run in safe mode. The cleaner is referenced & linked in this ASUS ROG forum thread - i know, it's a helluva note when the mfgr's own utility CREATES issues, and been doing it for years

fwiw

Here is my another post its not only tempretures that troll me http://forums.anandtech.com/showthread.php?t=2432459
I bet that's a vrm sensor. That/Your motherboard does not feature vrm heat sinks at all. Vrm's are record breakers at reaching the highest system temps. The less they are, the more they will heat up when power demand increases(when your doing OC). Your MB model is abudget model with a few phases(vrm's) and they are not cooled at all. No matter how efficient those asus "digital" vrm's are, they will still heat up when pushed hard. This theory is quite simple to check. Just revert to stock settings(non-oc), power off the system(let the pc cool down), and check that sensor's readings again! It should be way lower.
Just nothing to worry about. Vrm's are designed to work at the highest temps compared to other components like gpu's, northbridges, cpus's,...

VRMs get hot but temps should not be getting that high, actually not above 85'C, else you can expect hugely decreased lifespan. ASUS' FAQ regarding similar complaint suggests VRM should not be getting above 65'C, (recommends the motherboard temp warning limit in BIOS be set to 65'C):

Why does the temperature of this motherboard appear higher?

This particular FAQ was released for LGA775 era motherboard (P5Q Series) but VRM design has not fundamentally changed.

As far as having multiple HW monitoring utilities (and I/O drivers) installed or running:


When I enable PC Probe II and Everest at the same time, the temperature reading is erroneous.
