It might not be a problem. The threshold might not be the "damage to CPU
threshold", but rather a much lower temperature. Maybe it enters this
mode instead of increasing the fan speed, to keep the computer quiet.
This will give you a CPU that's fast in bursts but slows down if you run
it with a high CPU load for a while.

Basically, you have two temperature thresholds: The slow down CPU
threshold and the increase fan speed threshold. As long as the fan is
working and is allowed to run at full speed when needed you should be
alright.

Actually, the fan speed is probably not controlled by a threshold but
rather a nice curve, function of temperature.

There are probably nice articles about this. The Tom's Hardware and
such.

But it might also be a real problem.
