Something crrrrrr-ing inside my MBP (I have SSD, not HHD)

[Dias]

Hello guys

Since this morning my MBP '09 started to make some noise that worries me. I hope you can help me to understand what it is.

I've made an audio registration with my iPhone so you can have a better idea what I'm talking about. Btw, I have X25, not a HHD.

Thank you in advance for any suggestion.

EDIT: actually no, I'm watching Family Guy with VLC right now and cracking sound is still there. But it decrease if I decrease the volume. Also, I hear some kind of physical noise inside (like Superdrive or something like that).

Ok, I just noticed that the cracking sound comes from the speaker; if I play music or something that sound disappear.

Any idea why this might happen?

EDIT2: Nevermind, I rebooted and everything seems fine. Til now.
