kb3700_fanctrl is a Linux tool to control the Fan speed on MSI Wind Netbooks (and its clones). It is based on LGXfan created by Tord Lindstrom (pukko@home.se).

To compile it, run: "cc kb3700_fanctrl.c -o kb3700_fanctrl"

Execute it as root, e.g. "sudo ./kb3700_fanctrl".

The program works by writing fan speeds corresponding to certain temperature thresholds to the kb3700 controller.

Call kb3700_fanctrl with no arguments show the current fan speeds.
To set fan speeds, supply them (in percent) using the -f command line option: kb3700_fanctrl -f 0 20 40 60 70 80 100 100
The -r command line option resets the settings.
