One thing that is not working very well on Macbooks is the fan control. On top of the machine running warmer than under OS-X, the fans don’t kick in until it’s very hot.
To remedy this, you can write a program to do this. I got a source code of existing package called cmp-daemon (http://aur.archlinux.org/packages.php?ID=21391) and tailored it to my machine (The fan RPM is a linear function of CPU temperature, but you might want to change it to step function, for example).
The set-up is pretty simple. There is the source code cmp-daemon.c, and a bash script to start|stop|restart the daemon: cmp-daemon.sh (see attachments). Just follow these steps:
- Edit cmp-daemon.c to your liking
$ gcc -Wall cmp-daemon.c -o cmp-daemon
- Copy the compiled program:
# cp cmp-daemon /usr/sbin/
- Copy the daemon script (make sure it is executable):
# cp cmp-daemon.sh /etc/rc.d/cmp-daemon
- Start daemon:
# /etc/rc.d/cmp-daemon start
or edit /etc/rc.conf:
DAEMONS=(.. cmp-daemon ..)
