I tried to add my own config to the isw.conf like this, but the fan still does spin at 2700 rpm (at 36 Celsius):

How can I troubleshoot?
Hi Joe,
I'm running a modern 15 A10M-098, added a section for my EC, and was able to get the fans to turn off at lower temps. Did you try fiddling with the values much? My current config looks like what you see below. Note that the lowest fan speed seems to be about 2700-2800 RPM, regardless of how low I set the speed (greater than 0).
There is no gfx card in mine, and the second fan speed seems to be tied to the CPU fan speed (GPU temp always 0, but spins at same speed as CPU fan and seems to be tied to CPU temp)

Send 0xC2(194) to 0xF2 address - will STOP CPU fan spinning (in case low temperature): $ sudo isw -s 0xF2 194
I checked this on my MSI Modern 14 A10M (14B3EMS1).

Hello. You've missed gpu_fan_speed_6 = 100 in your config.
Anyway i can't do anything on the same laptop as yours, still getting PermissionError: [Errno 1] Operation not permitted: '/sys/kernel/debug/ec/ec0/io' on Ubuntu 21.04...
Oh nvm i've had secure boot turned on. After turning it off all seemed to work fine! Thank you for the config @elzuzax
Secure boot problems (when turned on) can be solved with acpi_ec module: https://github.com/musikid/acpi_ec Just replace /sys/kernel/debug/ec/ec0/i0 with /dev/ec at top of isw python script (after having properly signed the acpi_ec module on your distro) Tested on Ubuntu 22.04, secure boot on, and MSI Prestige
