My tank is 6 ft. x 1 ft. (looking at it from the top), and my canopy is approximately 4 inches wider than the tank (meaning there's open space between the back of the tank and the back of the canopy).
I would of course like to purchase fans that have good output, but that are also quiet. Any suggestions as to which kind of fan to look for? It sounds like a 12v DC fan is the preferred choice. I've got AH's 4x55 watt Bright Kit on it's way as we speak. How many fans should I implement? What about size and positioning of the fans? Will I need to be drilling holes in my canopy, or can I position them in the open space at the back of the canopy and still be efficient enough to cool the lights?
I guess what I'm looking for is the most efficient set-up that's still quiet (and of course something that won't cost a day's pay, but I'd rather spend a couple extra bucks on the fans than have to replace my light bulbs sooner than normal). I plan to hook the fans up to the same timer I'll be using for the lights. Obviously I'll also need a power supply for the fans, but will I need a transformer as well, or is this just necessary when the power supply doesn't match the fan's required current/voltage?
