I don't know where the temperature sensor is, but if very close to the
centre of the cpu, then yes it could heat up very fast indeed.

However, I've removed the fan from mine after it started making a very
high-pitched noise. That prompted Georges A. Tomazi to do likewise.

Since removing the fan, its speed is reported as something in excess
of 3000 rpm (can't recall the exact figure). Hence I would be
sceptical of believing the data in the BIOS.
