Thin mount rtadiator fan?
I always ran mine as pullers. I remembered reading an article early into my building experience in which it showed Pusher configurations losing between 30-37% efficiency at moving air as pushers as the air being pushed across the fan would ricochet off the fans themselves. As pullers they have minimal obstruction across moving air. Might not be true since this was years ago but hey it sounded right then lol.

Puller definitely, pushers are way too inefficient. I have a Cooling Components fan that's pretty thin and works well. Not the cheapest, but it doesn't sound like a 747 taxiing down the runway, but that's just a pet peev of mine.
