My exhaust fan stopped spinning, so I hopped on line and ordered another one. After looking at a service manual and one or two you tube vids, swapping them out looks pretty easy. Here is the catch. To do this you have to remove the processor heat sinks. This is easy enough with the right tools. What I don't know is whether or not you have to replace the thermal paste when you put the heat sinks back.
