I was thinking of using a 2" louvered eave vent for a strainer on my over flows.

Mine are like these but without the screen behind the louvers.

They will lay horizontally at the top of the tank via an elbow from the back panel. (back is drilled for external overflows)

Does anyone see any problems with these? Will noise be an issue? If so how can alleviate that?

not bad.

Might i recommend "gutter guard", available at most hardware stores.

or

Steel mesh, available at most hardware stores too

good luck
