ION 330 mITX motherboard (Intel Atom 330 + Nvidia) - CPU getting HOT
by ondoho from LinuxQuestions.org on (#54DVR)
This is a ~2009 machine I purchased (cheaply) to use as a home server.
It is supposed to be fanless, but the power supply has its own fan, and there's an additional smaller fan on the side (far away from the CPU) apparently for hard disk cooling.
Everything is working as it should, but the thing is getting HOT.

That's exactly how it looks in my case. The silver heatsink in the middle covers the CPU (I checked). It feels hot to the touch even when the machine is idle, with the case open.
I have configured 'sensors' with 'sensors-detect' and 'coretemp' reports on the CPU's temprature (there's another set of sensors for Nvidia's "stuff", those stay somewhere between 30 and 60 deg).
Running idle CPU temperature quickly rises to and stays at 85 deg Celsius.
Under stress it rises to ~90 deg Celsius - I stopped that after maybe 10min, didn't want to risk damage.
Whether the lid is open or closed doesn't seem to matter (I think when it's closed the hdd fan blows through the whole space, when it's open heat can dissipate upwards - both ways having roughly the same effect).
Anyhow, the spec sheet says the maximum temperature is 85.2 deg Celsius!
However:
Quote:
I'd say that's the heat sink.
I'd also say that "at" the IHS is vaguely phrased.
Does 'coretemp' report the temperature "at" the heatsink, or somewhere closer to the CPU?
Any hints why this machine is getting so hot?
I also asked the previous owner, they haven't answered yet.
