HP Pavilion Gaming TG01-1056ns : motherboard overheating

[dieniss]

Hi,

I got a HP Pavilion Gaming TG01-1056ns (like this one : https://support.hp.com/id-en/document/c07048438)

When the CPU is working a lot, the motherboard is getting very hot.

WIth a CPU test on OCCT, the CPU is going up to 78°c while the motherboard is going up to 100°c. So I stopped the test quite fast ! On HWMonitor I get the same temperature, so it's not coming from the software I guess. The Motherboard sensor that is getting hot is TMPIN0. I don't know where it is located. The two other temp sensor stay around 35°c.

Is this a common issue on that pc ?

Why the motherboard is getting that hot and how can I fix it ?

Thanks !

@dieniss -- is this your computer: HP Pavilion Gaming Desktop TG01-1056ns PC Product Specifications | HP® Customer Support

Where are the vents for room-temperature air air intake, and hot-air exhaust?

Are they "clear" -- not  having restricted air flows?

Is there a "chassis fan" on the inside of the back of the computer-case? Is it working correctly?

How old is the computer? Is it very "dusty" inside, such that the heat-sink on top of the CPU is mostly clogged?

Hi and thanks @itsmyname,

Yes it is that computer.

The intake air vents is on the bottom front on a side of the computer. It is the only one without any fan. I'm thinking about adding a little one at this spot (as we can see at 11m in this video : https://www.youtube.com/watch?v=Aoiwao7GhCM)

Hot-air exhausting is done by a chassis fan on the top back of the computer. It is working fine.

The processor is cooled by a top flow ventirad. Would it be better for my motherboard temp issue to have a tower ventirad if it fits ?

The computer is quite recent as it has a 3060ti and it is clearly not dusty inside the computer.

Can I unfix the processor ventirad without to change thermal paste cpu ? In order to check correctly the CPU.

@dieniss -- anytime that I have to remove the heat-sink, to expose the CPU, I always clean-off the old heat-paste, and add some.  It's so easy, and so quick, that there I see no reason to NOT be "proactive".

Years ago, a local owner/operator computer store would cut a hole in the side-panel, mount an exhaust fan in the hole, and connect a "grill" on the outside, to keep children's fingers from touching the spinning fan-blades. Add power from the power-supply.  Voila -- extra "exhaust", pulling more air through the case.
