Acer Aspire 2000: high pitch noise

Hi,

My Acer Aspire 2000 is making a very annoying high pitch noise. It is
comming from the fan grid in the upper right corner. It does not come from
the fan itself - it is not running. The sound is not constant - it is there
for 2-5 seconds, 1 sec. pause and then it starts again.
When the computer is busy - e.g. starting up a program - the noise
disappears for a few seconds.

Does anybody know this problem ?

Thanks
