Quite seriously, check it for excessive dust. Heat can do that. You can
also keep a baseline of that... Here's what I use:

    $ cat bin/heat 
    #!/bin/sh
    watch -n 5 "sensors ; top -b | head -20"

I also recently learned about cpulimit(1), which is really useful for, as
an example, transcoding.

Could easily be something else, but checking for dust isn't a bad idea.
