Actually, it could be related: on some of my laptops, when the fan
wasn't working well, I often saw both 100% CPU and a loud fan at the
same time, and both were due to the CPU's temperature (the system reacts
to too-high a temperature by increasing the fan speed, of course, but
also reducing significantly the CPU's frequency which in turn can cause
it to hit 100% usage even if there isn't a terribly high load).
