- Page 20 Subject 2: Suggestion on choosing electric fan Both the amount of electric current to MOSFET and the heat produced from the motherboard go up as AMD‟s CPU power consumption increases. In this case we recommend users select a CPU fan with air outlet towards MOSFET so that CPU fan can carry away heat produced by MOSFET, for better heat dissipation effects.
