NoteBook Fujitsu : fan problem

NoteBook Fujitsu : fan problem

I've just bought Fujitsu Siemmens Amilo L6820 (celeron 2400), and I've
noticed that when it gets hot, big noisy cooler kicks in. That's nothing
wrong, but I've also noticed that when I close power-demanding application,
fan is still spinning, for far too long than is really needed. When I
restart windows, fan stops in this instant, but without restart, it spins
and spins.
Is there any possibility to manually control fan operation? Or this is a bug
and I should consult tech support?
Any advice will be cheerily welcome.
