CONFIGURATION

20   USAGE
21       zcfan has the following default fan states:
22
23
24              Config name   thinkpad_acpi fan level   Default trip temperature (C)
25              ─────────────────────────────────────────────────────────────────────
26              max_temp      7                         90
27              med_temp      4                         80
28              low_temp      1                         70
29
30       You  can optionally override this configuration at /etc/zcfan.conf with
31       your desired threshold values in the following format:
32
33              max_temp 85
34              med_temp 70
35              low_temp 55
36
37       If no trip temperature is reached, the fan will be turned off.
38
39
40   HYSTERESIS
41       We will only reduce the fan level again once:
42
43       1. The temperature is now at least 10C below the trip point, and
44
45       2. At least 3 seconds have elapsed since the initial trip.
46
47       This avoids unnecessary fluctuations in fan speed.

DEPENDENCIES

51       thinkpad-acpi must be loaded with fan_control=1.
