X230 heat problem

[Kzlztan]

I'm in trouble because I installed Skulls on the X230.
If I use Qubesos, it will soon exceed 100 ° C.
When I repaint the CPU grease, it became better, but it is still hot.
I think the cause is that the control of the CPU fan has deteriorated.
Is there a way to improve the control of CPU fans?

@Kzlztan I have the same problem with T530. I amateurishly limit the CPU frequency by using a command-line program called cpupower. It has init scripts for whichever init system you are using so that you don't have to write it yourself.

In the beginning, I thought I couldn't apply the thermal paste properly. It took a while for me to notice that coreboot is the main cause. Compiling programs with all CPU cores became dangerous since PC shuts itself off after a while. Limiting CPU frequency with cpupower works for compiling programs. But I sometimes remove the limiter and speed up the fans manually, in case where I am not going to stress the machine.

I hope this helps you. If you find a neater way to fix this problem, I really would like to hear the solution.

having sold x230 for years, shipped with qubesos: it seems like your fan is the root cause of your issue?

You could try software solutions https://www.thinkwiki.org/wiki/How_to_control_fan_speed

But I would advise changing the fan. If it's not thermal paste, not the fan, then electrical problem... The x230 should behave decently without hacks under coreboot.

Running on a x230 without heat problems - I did reapply thermal paste. So this might be hardware related.

I'd assume so as well. Let's not close this issue just yet but I've not seen any differences with overheating. AFAIK coreboot can't really make difference in this regard.
