IMG 0792 (002) Fan in corrected position. Fan directed on condenser, where it can do the most work.

Do you have your fan setup as a pusher fan (or as a puller fan to draw hot air away)? I installed a 7 inch fan and I have it setup to draw hot air out and away from motor and condenser. I would be blowing real hot air into it here in Southern California in the summer months, so I have it pulling hot air out instead.

I set it up to draw air away and out of the cabinet. Yes you were thinking too.
