About Fan mounting

I received my 4" 110-120v Orion Fan with dust guard. This is the 110CFM model.

I am assuming the dust guard goes on the intake side of the fan.

I am not sure about options to mount this though.

1) I could try to put it on top of the overflow box.
2) I could try to mount it on the back of the canopy somehow.
3) Other option I can't think of right now.
 
I normally mount my fans to where they push air between the lighting and the tank, and have noticed good results this way.

Maybe some one has a better configuration though.

And the filter does go on the intake/pull side.
 
I have built a temporary lid/shelf for the overflow box. This allows cool air intake at the back of the canopy. I have put the fan on it blowing across one end of the T5's. The air exits where ever it wants since the back is open.

Although the fan is very quiet it is vibrating against the shelf and that is the noise I hear. Its not very loud, just somewhat annoying. I may tried some kind of foam under it and if that fails I may have to suspend it from the canopy lid.

One thing I cannot figure out is that the intake filter does not have holes through it for mounting. Am I supposed to drill out these holes or is it supposed to "hang" on the bolts that hold the fan?
 
I have mine blowing down on the tank but on my 29 I had it blowing in the back one on the left and one on the right about centred on the canopy.
 
you could use the zip ties with the screw hole in them and mount in to the canopy and let it hang where ever you want.

Regarding the vibration you can place a bead of silicone along the bottom edge of the fan. Once the bead has dried it should work to prevent the vibration. That way you are not losing the piece of foam if you go that route. You place the silicone along the edge and then cover it with saran wrap. You then put something with a little weight on top of the saran wrap until the silicone is fully cured. This will give you an even bead and a little flat edge along the silicone.

I did something similar with my fan but it was along the face of the fan.

Also you may want to experiment with the position of the fan and see if you get different temperature results. I found that having the fan blow the hot air out was better than trying to blow cool air into the aquarium. Mine is an inwall construction so I think that is why having the fans blow out worked best for me.
