Auxillary Cooling Fan Install Question

I'm going to install an auxillary electric fan and need some advice on location.

It's a 12" pusher fan that I can install in front of the a/c condenser or, I've got enough room to install it directly on the radiator sandwiched between the two.

Any advice on which configuration will offer the best cooling?

Outside in front of your A/C condensor is where it belongs.

Then that's where it'll go.

Thanks
