I've adapted it, my version is here[1]. How did you figure out the target temperature? I just run mine in a shell (it needs to be root to change those sysctls), is that the best way. My machine just panic'ed (sleeping thread) but I don't know if that was related to this program. References: 1) http://sites.google.com/site/tingox/powermac112-fancontrol-ti.c -- Torfinn
