Weird fan regulation in Lifebook E8020?

Hi,

I have the following problem with my Lifebook E8020:

After a while the fan goes on and won't go off anymore. It runs at low speed,which I guess isn't enough to cool down the system sufficiently so that the fan goes off again.

Why doesn't the fan run at maximum speed for a while and then go off again? Why does it have to run *permanently* at low speed?

I would like the fan a lot better spinning up from time to time with maximum speed and then stop again completely instead of running slowly forever.

Is there anything I can do to change how the fan behaves so that it behaves the way I would like it to (run and stop from time to time instead of run permanently)?

Hi

I've got an E8020 too, same behaviour. It seems this is a problem with every E8020, also those without ATI graphics (with Intel graphics it really shouldn't be necessary).
There is no solution. Of course many people also don't like if the fan runs at high-speed for a short time (see reviews for other notebooks) - so what is better...

Thanks for your reply. I too voted on the poll in the FSC notebook forum. But it appears there is hardly any feedback from FSC directly in that forum - unfortunately. Anyway, interesting thread and the most recent post there says that FSC confirmed the reproducibility of this behavior and that -just what you said- people did not like the fan to run at high-speed for a short time either. Well, I think it depends on how often the fan would run at high-speed. It wouldn't bother me if the fan ran every 15 to 30 minutes but every minute or so would be too often, I agree. But I don't think that would be the case. The notebook probably does not get so hot that this would be necessary.
