Does i8kutils work with the new XPS 13 9343 ?

Perhaps will work. Try loading module with "sudo modprobe i8k force=1" to ignore model check.

Using force=1
dmesg output:

Does it mean that it worked ?

I have the same question. Can't figure out does it work properly or not, but rather seems it doesn't.

"i8kfan" command with "- 1" and "- 2" parameters gives about 40-70K RPM in both cases. Fan can suddenly start to running. Temperature thresholds in /etc/i8mon completely ignoring.

I'm not sure that my settings of i8k correct at all, so can anyone confirm that?

If there is a file "/proc/i8k" so module i8k is loaded.

After that, if can set fan speed with i8kfan, then i8kmon is suposed to work if config files are right.

I'm using i8kmon with the modprobe you suggested. It works perfectly when unplugged but the fan doesn't slow down/speed up when "exec /usr/bin/i8kfan - 0/1/2" is sent while plugged in.
