How to make fan still works when system switching from uefi to kernel?

Hello,

I’ve noticed a specific behavior with the fan on my devkit during the boot process:

  1. The fan starts working immediately when I power on the devkit.
  2. And it suspends for a few seconds when the system switches from UEFI to the kernel. (It’s my thought…)
  3. After a short delay, the fan resumes operation.

My question is, is it possible to keep the fan working in this suspension period?

My JP version is 6.2. Devkit Orin Nano 8GB

hello ruei_chang,

please refer to developer guide, Fan Profile Control.
it’s due to userspace fan speed control daemon nvfancontrol to manages fan speed based on the trip point temperatures configured for the selected profile.
