Here in Massachusetts we get some crazy heat spikes, and we had one a few days ago bringing the tank temperature up near 84 degrees. That served as a hard reminder that something needs to be done to help keep the heat down from the two 250W MH lamps on my 75G tank.
I went on Amazon and picked up two Vornado 540B circulating fans. (One for each of my two tanks.) I figured that I could use them elsewhere in the house if they didn't work out.
They arrived in a few days and while they're a little bigger than I expected, they pack a big windy punch. And the two speeds should easily serve the dual purpose of both a quiet vent fan as well as a more urgent evaporation cooling when things get too hot.
Here's a quick video of one of them in action, demonstrating the two settings and the noise level.
