Need help to understand what makes that sound

[nakedear]

Hello! Some one can help me to figure out what makes this ping sound
http://dl.dropbox.com/u/15034031/Audio Recording 5 uz nerva.mov ! It sound like electric when goes wrong! Not rely sure if its ventilator!

Does it come from the left palm rest (location of HDD)? Does it happen while the MBP is stationary and not moved or hit?
And can you offer a less disturbed recording, as one might not really know what "ping sound" you mean?

And what exact MBP model do you have?

Ou, sorry that I not describe all normaly 🙂) ( I have MBP mac book pro 15''/2,53 GHz/4GB/320GB/) ;

spinnerlys: it comes from left top side ! Hdd is in right bottom side(hdd is ok)! It happens when I do something sound appear, and when I open mac book pro corps it disappear and I can't wait when it again appear to hear from where it exactly come! I think when I open corps temperature stay less and it not beeping , I try to work with opened corps and after time it appear again but when I lift up MPB to hear from where it came it disappears! That sound hard to record ! When I make mac book in very strong charge sound not appear it appear in medium charge! Sorry about my language 🙂)

Yeah, I always forget the orientation, as I visualise it open (I just opened it last week to put an SSD into my MBP, and hear no sounds). 🙂

What is "corps temperature"?

corps temperature when it appear is about 60 degree, that is CPU temp.
But it appear and disappear and in 80 degree it, appear disappear!
