[TRACKING] AMD FW13 fan speed jumps up high, drops quickly back to low / off

@Matt_Hartley Given the excellent write up from @Charlie_6, can this issue be handed off to engineering for a hopeful fix?

I can replicate on my fresh install (Fedora Kinoite 40 on Framework 13" AMD 7040)

I am tracking this for a resolution to the issue. The fan noise is changing my experience from “have recommended framework to others who bought one”, to: “going to set up a desktop and just use this machine when necessary, because the fan is so annoying”.

I hope there is a solution that can bring the computer into an acceptable function.

Is this fixable by setting your own values via ectool for the fan curve? I believe you can customize the whole table.

I have not tried yet but I do get pulses sometimes. I have not attempted to rectify the issue.

actually the real problem is this Fan_off temperature 376 K, which is 103 DegC! Thus the fan never speeds up before frequency throttling. Reasonable fan_off temp should be 40-60C, i.e. 313 K - 333 K
