Just make sure you take a paper-clip and open it up and put it through the fan grill to hold the fan stationary before you take a vacuum or shop vac to the air intake/exhaust. You run the risk of scattering or damaging the fan(s) if you just let them freewheel. After a minute or two of suctioning, you should see several lumps of fur on the inside of the grill which can generally be removed easily by rubbing across the grill with your hand, (or) using some duct tape to tease the fluff through, (or) in the worst case using a pair of tweezers and needle to pick the hairball through. And yes, it will completely cure the overtemp shutdowns for a year or two...
