Show HN: An AMD GPU Fan Controller for Linux, in Rust

This was how I spent my Saturday. Needs a bit of polish, but I'm pretty happy with how it turned out, i.e. it works and my PC hasn't exploded yet.

There's an equivalent in Python that I've seen, but this felt like a good use for Rust to me. One feature I specifically wanted was for it to run the fans higher for longer, so that it doesn't just sit at a temperature boundary turning the fans on/off all the time.
