A/C condensor pusher fans

[Stocker]

Had a third shop work on my A/C and it finally seems good.... with one exception. I was told I need a couple pusher fans in front of the A/C condensor, because at low speeds (or at idle) there's virtually no air passing through the condensor. It's in the stock position but sits too far from the radiator. With a big gap at the top and a smaller gap at the bottom, most air to the radiator is bypassing the condensor.

If any of you have added pushers in front of your condensor, what did you use? I searched a bunch of threads but didn't find what I'm looking for. Summit has thousands of fans and it's hard to know where to start. Thanks for any help!
