MBP keyboard noise

Ok Ok yes I know there is a search feature, but when I searched I didn't really find what I was looking for.

Anyway, whenever I move a window around, scroll within SAFARI using the TRACKPAD (doesn't make noise when using external mouse), "show all windows", or go into spaces, my computer makes a subtle noise coming from the keybaord. I searched and realized a lot of people have this problem, but I couldn't find a solution.

This is not a constant noise, it only happens when I do the things listed above.

Any help would be appreciated.

 

Ok someon has the exact problem I have the thread is called

2.4 Penryn MBP Ticking/Clicking Noise

I've concluded it only happens when GPU intensive stuff is going on i.e. gaming in XP, scrolling in OSX, moving windows in OSX.

This is not a subtle noise

Should i return?
