I don't always agree with industry cooling setups. When I was in sound engineering, Biamp made a professional amplifier with overheat protection that shut everything, including the built-in cooling fan, off when the temperature got so high. The amp would have turned back on a lot sooner if the cooling fan had stayed on.
