 Provides easy setup and monitoring through graphical GTK+ interface. Temperature thresholds can be set separately for each sensor since version 0.90.

	The code lets you define a temperature range for each [[thermal sensors\|thermal sensor]]. The script computes the fan level needed by each sensor based on the configured range, and then sets the the actual fan level to the slowest that will satisfy all sensors (plus some hysteresis to avoid fluctiations). It also includes a workaround for the [[Problem with fan noise\|pulsing noise]] problem. The script provides an (optional) daemon mode and logging to syslog. The method of controlling fan speed is documented [[How to control fan speed\|here]].		The code lets you define a temperature range for each [[thermal sensors\|thermal sensor]].

 This little piece of python code is only there to speed up your fan in a T400 with an ATI card cause the fglrx driver does not control the fan speed which leads to overheating while gaming or do other graphic stuff with the ati chip. This script relies on the normal bios control of the fan. If the laptop gets to hot it will speed up the fan to max speed (somehow the bios does not do this ??!!) and re-enables the bios control on a certain temperature. This was only tested on a T400 with ATI chip.
-You can just run in in the background as root. It is very chatty and writes in a logfile in /tmp. It should work with any Thinkpad who has /proc/acpi/imb/fan interface.

-Written in C to use as little CPU power as possible. Configuration is done via a simple text file, by providing (FAN_LEVEL, LOWER_LIMIT, UPPER_LIMIT) tuples. Inspired by i8kfan. Requires thinkpad_acpi with fan_control=1. For Gentoo users there's an ebuild and an initscript. Just released version 0.5, which now supports any hardware through the sysfs hwmon interface.
