I've been suffering from occasional power offs with no warning, and I suspect the CPU is getting too hot. On the most recent power off, the computer once again powered down during the bootup phase (before the EFI boot screen). To me this solidified my suspicions. I have a a thelio-massive-b1 with 2 Intel(R) Xeon(R) Gold 6238 CPU @ 2.10GHz I patched the source making the xeon fan curve more aggressive and the maximum CPU temperatures are now a little lower. Under low system load there is no noticable difference in fan speed. Plots of CPU temperature, fan speed, and fan command are attached as comments to the commit on GitHub.

Here are some plots showing the before and after with the patch applied. The new system76-power was enabled at 20:00. (Data points were collected once every 5 seconds for plotting.)

Feel free to further tune the new fan curve. The point is to lower the maximum temperature where the fan goes to 100%. From the plots it is apparent the old fan curve results in a more steady fan speed, whereas my new one causes the fan to jump around a lot more. |
