What would make a noise in a PC on graphics operations on a passively-cooled system?

Every time i scroll (either with the scroll wheel or scroll bar), and it affects a large part of the screen, my laptop cheeps/whimpers. It's a quiet and high sound - like "tsiiii"...
It has nothing to do with the sound card nor the internal speaker (These are disabled). I know some people that are faced with the same "issue".

Sound's weird, i know. Any ideas?
