+systemd configuration or script in /etc/rc?.d.
Every 5s, \fBbreezed\fP gathers all integer values from the thermal
files, and takes the max as the overall temperature T. It then
speed one level below. This two degree gap avoids too many
oscillations. Also, the daemon waits for at least 30s after any change
of the fan speed before reducing it. The fan speed is set by writing
-"level <level>" into the specified fan file.
+"level <speed_name>" into the specified fan file. The speed name is
+the level itself if no alternative is provided with the temperature
+threshold.

.SH "CONFIGURATION FILE"
Starting it with all the arguments on the commande line can be done
for instance with
-breezed --no-configuration-file \
- --thermal-files /proc/acpi/thermal_zone/THM0/temperature,/proc/acpi/thermal_zone/THM1/temperature \
- --fan-file /proc/acpi/ibm/fan \
- --temperature-thresholds 52,54,56,58,60,62,64
