I rewrote the fancontrol script, and added a hysteresis to the fan speed calculation. This prevents the fan from being switched between off and minimum speed every $INTERVAL seconds because the temperature changes by 1?C. Another important change which allows fancontrol to be started from the lm_sensors service script is also included. The syntax of /etc/fancontrol is appropriately extended, the change will be ignored by previous versions of the script. Please replace the fancontrol script in the lm_sensors package with the one at http://volker.dnsalias.net/soft/script/fancontrol . No diff because it's a complete tidy-up, with many clumsy parts being rewritten.
