mbpfan (fan control daemon for Apple MacBookPro machines) A simple daemon to control fan speed on all MacBook/MacBook Pros (probably all Apple computers) for Linux Kernel 3 and newer. After installation you must add below to /etc/rc.d/rc.local: if [ -x /etc/rc.d/rc.mbpfan ]; then /etc/rc.d/rc.mbpfan start fi and ensure /etc/rc.d/rc.mbpfan is exec (0755) Also edit /etc/mbpfan.conf and uncomment min_fan1_speed & max_fan1_speed I have found a min of 3000 and max 6200 work well for my mbp.
