i8k i8kmon – dell xps m1730 fan control on Ubuntu Linux

How to control the fan better on Ubuntu with i8k on a Dell XPS M1730.

Install i8k

In /etc/modules put this:

i8k force=1

create a file /etc/i8kmon.conf with this in it:

set config(0) {{1 1} -1 30 -1 35}
set config(1) {{2 1} 29 50 34 55}
set config(2) {{2 2} 49 122 54 122}
set config(3) {{2 2} 120 128 120 128}

edit /etc/default/i8kmon and change ENABLED=0 to ENABLED=1

Run this:

/etc/init.d/i8kmon restart

It will sound like your XPS is about to take off! Especially if you haven’t heard the fans run before (which I hadn’t).

Alternatively you can manually control the fans with these commands:

i8kfan 0 0  (both fans off)
i8kfan 1 1  (both on low speed)
i8kfan 2 2  (both on high speed)
