I'm running Pop_OS 20.10, which is an ubuntu variant, and uses systemd.Īs far as I can tell, updates to the bios (at least after 1.10, can't tell you about before that) were mostly to fix intel processor architecture security flaws. I have a Dell G5 5590 with an i7-9750H and an RTX 2070MQ. Here is how to manually control your fans and set a custom fan curve, instead

It reduced performance on the processor permanently, though, and for some takes away the ability to undervolt. Updating the bios did not fix my fan behavior. The pwm outputs connected to the fan connectors,Īlso, even if I finish the pwmconfig setup and run the fancontrol service, there's no change in the fan behavior. Or the connected fan has no rpm-signal connected to one of There is either no fan connected to the output of hwmon7/pwm1,

I've installed fancontrol and tried to set it up as described here: - the pwmconfig tool is able to switch my fans off and on during calibration, however, after calibration it says:.

I've installed i8kutils and ran sudo modprobe i8k force=1, now I'm able to see the fan speed in psensor GUI, as on the picture below.I've installed lm-sensors, set it up with sensors-detect and added coretemp to /etc/modules.I've looked in the BIOS settings, but found no settings related to fan control.This is very annoying, and I'm not sure it's supposed to be this way, since I'd expect a more gradient fan control. My fans are constantly switching on and off with a period of 30 seconds (30 seconds full-speed, 30 seconds completely off), even without any processor load. I have a Dell G5 5590 with Ubuntu 18.04.4 LTS.
