I second this, it’s why I went with Bazzite on my main rig - it just needs to work and be reliable. The last thing I want to be doing in my spare time is funking around trying to fix anything that happens to break.
All my other devices run whatever I feel like so I can scratch that curiosity-itch but they get reinstalled if anything major breaks and I can’t fix it in a reasonable amount of time
12v fans will typically run fine, albeit much slower at 5v. This was a favorite trick many moons ago to reduce fan noise in desktops before quiet fans became mainstream. The main watch out is that the fan doesn’t stall at startup and fail to spin completely.
