SuperMicro motherboard show 'IOH overheating'.
 

Hello Folks.
My friends has a Supermicro motherboard That show him 'IOH overheating'. The Model is :

Unfortunately, he use Windows server and use some Windows Tools for Monitor hardware. Each tool show different temperate and I want to test it via Linux and find the real Temperate. I know some Good linux tools for Monitor hardware but my problem is that why on Windows different tools shown different temperate. any idea?

Cheers.

Heh, yesterday I fixed CPU overhitting at Gygabyte mobo.
I tried 4 different Windows tools, including HWMonitor. No one shows correct temperature. CPU heats up to 100C and modo powers off due to overheating while HWMonitor shows 37C only.

Just enter the BIOS and check temperature directly from there.
If it is absolutely necessary to check temperature from Linux, you have to install and configure lm-sensors.

I guess this problem can be solved via BIOS update. What is your opinion?

If it is really overheating, you can't solve it via BIOS. But you can control temperature via BIOS.
Enter BIOS and check for CPU Temperature and System Temperature.

If you haven't already done so, make sure that all the air vents are clean and not clogged with dust. If this is a desktop, open it up and check for dust build up inside, particularly on the CPU heat sink; make sure the vents for the power supply are clean of dust and other obstructions. A can of compressed air is very handy for this.

If it's a laptop and it has vents on the bottom, make sure that user is not actually resting it on his lap or on a soft surface, such a couch or a bed, that might block the air vents.

I wouldn't recommend to use compressed air. It is very likely that compressed air may contain droplets of condensed moisture. There is the risk of getting these droplets on the motherboard. If it is really clogged with dust, use vacuum cleaner instead.

I would doubt that myself seeing as the compressed air is sold for precisely this kind of situation. Plus, water in small droplets on its own is unlikely to be a problem. You may be right but I've not heard it before and I've spoken to a lot of electronics and IT techs who use it.
Edit: Plus, received wisdom has it that a vacuum cleaner nozzle is likely to be statically charged which could cause problems. That and a vacuum cleaner is more difficult to control and position than the "straw" of a can of compressed air.

You may use a container with a compressed air if you are pretty sure that the air has been dried before compression. Otherwise I wouldn't use it.
But people tends to do strange things. People often use an occasional source of compressed air, mostly a compressor for pumping tires. It is so obvious - go to the nearest tire shop and blow the dusty laptop... No one of them thinks that such a compressor may have up to 5 litres of rusty water inside, especially if it wasn't cleaned and dried for a year or two.
And yes, I saw such a "cleaned" laptops with a rusty water inside which I was asked to repair.

Ah, yes, I agree about not using any random shop compressor to clean devices.
When Frank bell mentioned "a can of compressed air" I took him to be referring to those cans you can buy labelled as "air duster" and such which are manufactured specifically for clearing dust and debris from electronics.

Exactly. They've become so common that now even my drug store sells them.

There is no way that temperature is right, look at the maximum value 379 C ? Check the BIOS values.
