I am going to have to add an aux cooling fan to my 2000 LS V-6. Living in the desert means the stock cooling fan just can't hack it during 100+ degree days here with the A/C on. I want to mount a pusher fan on the front of the condenser for additional cooling. Is there any big difference between Hayden or Flex-A-lite fans? Right now I am leaning toward a Hayden 3911 Super Duty 12 inch pusher rated at 1275 cfm and 12.8 amps. All cooling system plastic has been replaced.
