Open the Console.app and take a look at these logs:

/var/log/system.log
/var/log/kernel.log (Snow Leopard only)

If you see anything that says:

disk0s2: I/O error

then it's the hard drive.



Otherwise, if you could determine what area of the laptop it's coming from, I could potentially tell you what it is. I'd also need to know which MBP it is.

it is the one in my signature and it coming from the left side by the keyboard

On that machine, the hard drive should be in the front left, under the palm rest. There are two fans in the machine, and from what you're saying, it sounds like it's likely the left fan (under the keyboard, at the rear of the machine).

The detail about clicking a link in Safari is probably more related to the fact that loading a web page requires processor usage, and therefore, the fan spins up a little bit. You could probably get it to make the noise by manually spinning up the fan using something like smcFanControl.

If your machine is still under warranty, just take it in.
