I'm interested. The fan on my Pi 5 started to fail last week after a bit 
over a year of use (mostly ~1hr a day to run regression tests, but 
sometimes much longer). The fan usually runs at full speed.

I might be able to help a bit. I'm not a kernel dev but I have plenty of 
experience with C and syscall interfaces.

A+
