If you have to mount your fans in front of the radiator make sure you check with the supplier that the fan is capable of being converted from pull to push. The fans that I used are not and had to be ordered as pushers, but still work fine.I have no engine driven fan and only 2 small push fans mounted on the a/c condenser (a 10" and a 9") the condenser is sealed to the radiator support and the support is sealed to the radiator (so air can't escape from going through the radiator) and on a 35degC day stuck in traffic the fans are still not running constantly and temp gauge still sits on half way.
