Steps to reproduce:
1. power on pc.
2. hibernate.
3. power on pc (this resumes from hibernate)
4. run some 100% CPU intensive tasks

What should have happened:
the thermal information updated to indicate that the CPUs were getting hot,
resulting in the fan speeding up.

What actually happened:
the thermal information reported was the temperature before hibernation.
Running some 100% CPU tasks goes unnoticed until a kind of emergency alarm
kicks in and the fan goes straight to its top speed - I haven't waited for this
recently as it seems a bad idea to rely on.

A reboot restores the CPU thermal information and shows the CPUs are still a
bit hot but the fan behaves normally to cool them down and the temperature
falls.
