This post is about getting temperature monitoring to work with a Mac Mini running Linux.

Using Debian Lenny, out of the box, lm-sensors is not working. No sensors can be found. This is how temperature monitoring and fan speed monitoring can be made to work:

modprobe applesmc

If you run "sensors-detect" after this, and do a:

modprobe coretemp

Then "sensors" will give you ouput like this:

Mini:/sys/devices/platform# sensors

applesmc-isa-0300

Adapter: ISA adapter

Master : 2151 RPM (min = 1500 RPM)

temp1: +83.2°C

temp2: +68.0°C

Some software to control the fan speed:

When using a Mac Mini as a server or router, it is very nice if the machine automatically boots if a power failure has occurred.

User chirhoxi on the ubuntu forum found out how this can be achieved:

Basically you need one of these commands:

Original Mac Mini:

setpci -s 00:03.0 0xa4.b=0

Newer Mac Mini:

setpci -s 00:03.0 0x7b.b=19

These commands might not work with the latest Mac Minis but the thread discusses how to determine for yourself what the appropriate command is.
