ghost commented 5 years ago

when i use i8kmon or i8kfan to set the fan speed it will set when after about two seconds it will go to something else can i disable that or make i8kmon set fan speed faster like every second?

Same issue here. On a XPS15 9570, i8kmon sets the fan speed as expected whenever a temperature limit is crossed. However, after approx 1..2 seconds, the default speed is again applied to the fans. Repeatedly executing i8kfan commands at a high speed can make the fans spin. After each time i8kfan is executed, the default speed is applied after approximately 1s.

I had the same issue. It is caused by BIOS conflicting with i8k. I installed this https://github.com/TomFreudenberg/dell-bios-fan-control and after disabling BIOS it worked like magic :) I am on a Precision 5520

This also has been reported in Linux: https://bugzilla.kernel.org/show_bug.cgi?id=200949. I wrote a patch for the Linux dell-smm-hwmon module, and will try to submit it to upstream Linux.
