zcfan is a minimal, zero-configuration fan control daemon for ThinkPads.
zcfan does not take any options. If any are provided, a help message will be printed and zcfan will exit.
zcfan has the following default fan states:
|Config name||thinkpad_acpi fan level||Default trip temperature (C)|
You can optionally override this configuration at /etc/zcfan.conf with your desired threshold values in the following format:
max_temp 85 med_temp 70 low_temp 55
If no trip temperature is reached, the fan will be turned off.
We will only reduce the fan level again once:
- The temperature is now at least 10C below the trip point, and
- At least 3 seconds have elapsed since the initial trip.
This avoids unnecessary fluctuations in fan speed.
thinkpad-acpi must be loaded with fan_control=1.
