Excessive fan noise

[Fluffy537]

My wife is complaining about my noisy laptop. She is right. It is noisy and not just when thrashing the CPU or GPU, like playing games.

If the CPU usage gets above 10% then the CPU temperature goes above 50 degC and the fan comes on full blast. It stays on full blast until the temperature drops to 40 degC. This is the idle temperature. The GPU is at 35 degC. The disk drives are not being accessed.

The BIOS has been updated to the latest (F20).

Windows and the drivers are up to date.

I have tried underclocking, but temps only dropped by 1 or 2 degC.

Fan intakes are clear and clean.

Not had the laptop long enough to accumulate dust in the fan.

Performance control is on comfort.

Is this normal temperatures?

I would have expected the fan to ramp up speed with temperature, but appears to be either off or in tornado mode.

My daughter has a laptop of a similar spec (Different manufacturer) and that is nothing like as noisy.

I had it serviced and it was diagnosed as a faulty thermal unit.

What I think would be useful here is a guide to expected behaviour so that people looking at this ticket in the future can ascertain whether they have a possible faulty laptop or whether the behaviour is as expected. Therefore a set of rough ballpark  temperatures would be useful. I appreciate that this is not an exact science, but some broad expected values would be useful.
