Can anyone help me diagnose this noise that comes out of my Macbook?

Only comes out sometimes, sometimes when certain applications are open. Goes away when they are closed, but sometimes it stays on when no applications are open.

Sorry that its a download link but I dont have a youtube account :/ Its a very short 10 second video taken from my phone

Thanks for any help, I've never been able to find a solid answer on why my macbook does this.

Hard to tell but sounds like the bearings are shot in the fan...

Probably a lot of dust in it too....

Take the top case off and you will be able to hear what is making the noise....

I didn't open it but I think I have the same problem... kind of sounds like this:

It only happens when the comp is doing a lot of work so it has to be the fan. when I tap the area where the fans are the sound goes away for a moment but will then return! I could post a video if needed. I should probably clean out the fans. How do I go about doing that? Take off top case - Is that the only way?
