I was thinking of adding fans to my HE (heat exchanger) before I got the larger HE, but now that I have the larger HE I can't install fans behind it because of clearance issues. Would putting push fans in the front of the HE work well instead of using pull fans that would fit behind it? I know they would be blocking some air if not turned on, but would it be a significant blockage or would the benefit of them being on make up for it?
These are the fans (two side by side) I was thinking of going with:
