Doug, A collaboration between power supply and board designers led to the setup where the power supply cooling fan blows directly on the processor heat-sink. This makes it possible to eliminate an extra fan-sink and reduces malfunctions due to excess heat. In order to obtain these benefits, the processor must be located at one end of the board where air from the fan can _ pass over it, and the chassis must be designed to hold the power supply in the correct position.

You may want to look at that. I can't say that inside fan mounting is better, though.
