How close, is to close for rad fans to water pump pulley space

How did you mount them?
Kind of directly to the radiator..
I use those push through zip ties with a little padding. I also got a bolt or two through the top and through the bottom.

This is a cheap Summit radiator and I found that to have quite a bit more volume than my stock one did. I haven't tested it in the Dead Heat of summer yet but I was thinking of one of those Pusher fans or just trying to get a thinner singular fan upfront or back behind the radiator. I don't think I'm done yet but I'm nowhere near or even considering putting back on the whirling blade of death...
