How to clean the cooling fan on a wide variety of laptop or notebook computers (which one is your's anyway jlb?) is shown here at
Repair4Laptop.
One common theme - close quarters - making it a job for nifty fingers. The tutorials show simple clean out / lube / or replacement.
MicroCenter or NewEgg should have replacement fans for most widely available models.
The earlier linked site also has cooling upgrades that can be applied in some instances.
Good luck and keep your cool
