Canopy fans question (1 Viewer)

[PuffersRule]

I just finished building my custom canopy for my tank and am about to install one 4 3/4" cooling fan on each end of the canopy.

My question is how to install the fans. Do you install them to blow cooler air from the room in the canopy, or suck the hot air out of the canopy? Or do you do one of each, where it sucks cooler air in on one end and then expells it out the other end?

Thanks!

Do one of each. Also if you are able to place the fans on top pulling heat out that also works very well.

You might want to have both fans blowing into the canopy. If you have them sucking out of the canopy, they will build up gunk over time ,as in salt residue and anything else in the air. They will still accumulate dust, debris from your home air if they are blowing in, but it is alot less and takes longer to build up. Just make sure you have good ventilation no matter which way they blow.

I would have them blowing out as yes they will build up salt creep but you wont be blowing dust and other airborn contaminates into the tank from the room. If you decide to have them blowing in then I have heard of people using filter floss or a thinner air filter medium to help with airborn particles going into the tank. Filter floss may be too restrictive IMO but it would bepend on the fans also.

LOL,

OK so that's

1 vote for both in
1 vote for both out

All of those are viable options. Everyone has their own experience and perspective. If the fans are easy to get to, you could try different options and find that one may or may not work in your situation. My fans have plugs that can be reversed to turn the motors either direction, maybe yours does? Just be sure that you have good ventilation, the air you push in or pull out must have a way out or a way in.

Actually I have not bought the fans yet. I have had a hard time deciding on the ones that i want. Do you have a link to the fans you bought?

And my canopy has an open back and open top. Just solid front (with access doors) and soild sides. So it is not completely enclosed. Therefore I'm thinking blowing cool air IN would be best then the hot air will rise OUT of the back and top.

visit fry's, go to the pc section and get ball bearing 120mm fans, spins slower pushing more air and less noise.
you might want to put a filter and grill over the fan to help keep dust build up on the blades if you go with the push pull system.(in and out)
I would blow cool air in from the sides and hot air out the top.
nothing from the back as you can cause dust buildup on the wall.
IMHO
