Best for continuous Underwater operation: Amarine made Marine vent Fan

Buy on Amazon

The amarine made marine vent fan is capable of outshining several other fan featured in this list in overall features for the price point. It is not particularly quiet, but few blowers are, especially ones that move a lot of air. It is just the amount of air moving through the blower, the sound is very little compared to the amazing output and low amp draw. The heat generated by the exhaust will in the very least melt the housing and fan blades and more likely catch fire. There is an arrow on the housing that shows direction of flow. It is designed to run in one direction.

It draws about 3.6 Amps at 12 V and around 40 Watts. It really works for a computer fan. It would be easier to just turn it around as the fan blade is designed to run in one direction.
