You can get fans with colored LEDs as well. I used to have a set over my 230g and they made for nice evening lighting. They were more expensive, but it was worth it.

For the ultimate quiet fans, I used 220V computer fans - but wired them with standard 110V power. That way, they run at 1/2 speed. They are still effective, but they never reach the speed that generates that "computer fan noise".

The only risk with this approach is that the bearing on the fan must be good, or the 110V won't kick start the fan. While I was warned about this when I purchased them, it has never happened to me.

I agree. I have 2 x 120mm computer fans blowing into the canopy. Granted that your canopy is not 100% air-tight (duh, who's is?), the warm air will find pathes of least resistance to get out of the canopy.

Some advice, only have you fans pulling air into the hood, as they will last longer. If they suck it out, they wont last as long due to the salt and other harsh environment that it sucks through the fan. Mine are strong enough to blow all the warm air out. You can get the 120v ones that can be wired to a switch, or a 12v one with adapters to plug into a wall, etc.

also you can just cut a hole at the top or a slit even in the back as hot air rises, with the positive pressure in the canopy the air will be sucked out naturally.

I think panaflo fans are great and you get something much higher quality than those cheesy icecap fans. Compare the specs of an icecap fan to a panaflo and they don't come close and the panaflo fans are very high quality. Not something no-name rebranded by icecap. I think if you were to mount the fans on the top of the canopy and drill a few holes or carve out a slit on each side to allow air inwards would be a great flow design. That's from my experience with computer airflow design.

The problem is that the exhaust fans at the top will be pulling out HUMID air. Therefore they will corrode very quickly.

You dont have to have exaust fans in an aquarium canopy. The air WILL get out, dont worry. The point of the fans is to move air across the water surface to help evaporate the water.

Evaporation = Cooling.
