Subject: [PATCH] Make xeon fan curve more aggressive
|
|
|
|
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.
