FAN RUNNING

If the fan is constantly running at high speed, then you need to check Activity Monitor for an application or process which has a high number of CPU cycles.

Try running the Apple Diagnostic.

You can also post an EtreCheck report here using the "Additional Text" icon which looks like a piece of paper.

You could also try an SMC reset & PRAM reset, but I don't think either one will help in this case.

That's expected behavior. The fan is constantly running.

Is it excessively loud? Is your battery life significantly lower than usual?
