How to adjust the rotation speed of the coolers?

Question

Arch Linux

Here's what it gives

Following the instructions on the Arch Wiki, I prescribe

$pwmconfig

/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed

How can I fix this, or is there any other way to reduce the speed? It's getting harder and harder to work next to an airplane, and a replacement is not yet possible (and won't be for a long time)

Answer 1

If the coolers are connected via a 4-pin connector (with rotation speed control), then you can do it in principle, otherwise only in hardware (resistor).
For example, through the BIOS, if you're lucky, there will even be advanced settings for at what temperatures and at what speed to rotate. In old amd bios, there may be points - cool and quite, this is just a technology for controlling the rotation speed automatically from the load.
