weird noise, audio clip included

[awakenlol]

Hey guys, new here. So im resorting this old r50 that i found and pretty recently i started hearing a noise coming from the grill where the air comes off the CPU. So im guessing the problem is something to do with the CPU fan. Im not 100% sure though and id like to avoid buying a new fan and heat sink assembly if possible.

Here is a audio clip i got of the noise lol: http://vocaroo.com/?media=vSlWBnLFsmxr7CNIi

Thanks for any help

It sounds like the CPU fan to me. Remove the keyboard, and blow out the fan cavity and exhaust fins with compressed air. Hold the fan blade still while doing this. If that improves things, great. if not, replace the fan.
