Clicking sounds with MBP (not speakers/audio related)

[lauph]

Hi,

This has nothing to do with the audio hiss issues, but another thing i found in my SR MBP.

When theres any animation going on in the screen, theres this rapid clicking sound coming from somewhere, i still dont know where(it is around the fan vents the grey rubber strip below the silver "MacBook Pro"), but i know for sure it is not from the internal speakers.

as i said, it is not audio related so muting or having music playing or connecting external speakers did/does/will not affect this problem.

Things that will produce this rapid clicking sounds:

Dashboard
Exposé
Front row
Genie Minimise effect
Scrolling a webpage
Games
Videos
(anything that animates or moves)

so i would say when there is any change in the display(when it is "active"), there will be this clicking sound. When the display is idle, it is silent. Even in slow motions (Shift+F12) the clicking is produced.

Anyone else have this problem?

ok i found out i had to sleep the MBP then, wake it up, then there will be this clicking sound. When it is freshly Booted, there is no sound during the display activity.

anyone can try it out please?

Shortly after I bought my MBP, I noticed a clicking noise too. I have not noticed it recently, however. I will check again later, because I did not expect that other peole were having the same issue.

I always figured that it was the processor doing some calculations, but call me dumb, I know nothing about hardware really. Heh.

I didn't expect this to happen when I got my MacBook a few weeks ago, but I thought this was normal. Every PC I ever had did this, too.
