NAME

zcfan - zero-configuration fan control daemon for ThinkPads

DESCRIPTION

zcfan is a minimal, zero-configuration fan control daemon for ThinkPads.

OPTIONS

zcfan does not take any options. If any are provided, a help message will be printed and zcfan will exit.

CONFIGURATION

USAGE

zcfan has the following default fan states:

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.

HYSTERESIS

We will only reduce the fan level again once:

	1.		The temperature is now at least 10C below the trip point, and
	2.		At least 3 seconds have elapsed since the initial trip.

This avoids unnecessary fluctuations in fan speed.

DEPENDENCIES

thinkpad-acpi must be loaded with fan_control=1.
