dual GT AP-15's vs single GT AP-29

I was thinking of buying a couple of GT AP-15's for my Kuhler 620 rad, but now that I have bought a fan controller, I was wondering which was the better buy.

I'm sure the low RPM dual fans will run quieter at max speed than a single high RPM fan,
but will a single AP-29 cool the rad more? I can always run it at low RPM when I'm not doing anything.

Can anyone shed some light on this?
