note: if u have not un-assembled a laptop before I don't recommend it, the plastic pieces are easy to crack if u don't know what yer doing.

I was just going to say.. telling someone who obviously has never taken apart a laptop to do so is NOT a good idea at all..

Blowing air in is not a bad idea and hey if it fixes the problem then you're golden.. I would try that first before going any further.. Very rare with a laptop though that a lot of dust is going to get in there just because they are so tightly packed in the first place.. This happens more so with desktop computers..

I would say it's more than likely even though your fan is running, it's probably not running at it's original speed and it's probably the bearings themselves that are fux0red so the fan or fans themselves need to be replaced..
