I know there are several programs out there that adjust your fan speed based on temperature readings. However, I couldn't find one worked well on my system, so I wrote my own. This program takes a very simple approach: if the system is too hot, the fans run on maximum power, otherwise they run at minimum power. The reasoning behind this approach is explained at length here: http://www.lshift.net/blog/2006/06/26/thermostat-defeat and the resulting program, in C, is available here: http://www.lshift.net/downloads/fankuchen-v0.1.tar.gz This is now running on my system and I'm very happy with the results. Should this be the program that ships by default with lm-sensors? Let me know what you think. Thanks! -- [][][] Paul Crowley [][] LShift Ltd [] [] www.lshift.net
