It’s been a while since I noticed that but I can’t find the reason. I selfhost :

  • a linkding with docker
  • a writefreely
  • a bludit blog
  • a CalDav (radicale)

There is a syncthing running for backups done with borg at night (automated with a crontab).

When I htop, I don’t see anything to hint me to what is causing the heating.

Any ideas of what I could do to investigate that?

Thanks a lot.

    The backflow current from fans is extremely minuscule and extremely unlikely to damage anything from that. There are even tests using a damn leaf blower on the fans and it barely generated any current. Even if it did generate a backflow, diodes on the mobo should prevent it from becoming an issue unless it’s a power so great that it just fries everything, but that’s basically impossible with a fan.

    Here’s one such experiment.

      Yeah. You’re more likely to physically damage it by hitting the little plastic blades with too much force at the wrong angle.
