Public bug reported: When I turn on the PC, the fan runs normally and I have no issues at all. However, if I suspend the computer and resume it, the fan runs at full speed, regardless of the actual internal temperature. This is very annoying in libraries.
This bug has been around for years, I just didn't need the computer in quiet places back then, so I never reported it. I believe it didn't happen with Maverick. I'm running Ubuntu 15.10, with Linux 4.2.0-14-generic x86_64 (systemd).
