(2) 12" fans versus (1) 16" fan

Getting ready to order a new Champion 4 core radiator...I'm thinking having the redundancy of 2 fans would be a good idea, and that one 12" fan will likely maintain engine temp, while using the 2nd fan in traffic or after a hard run at the track. Has anyone studied this? A couple of notes: 12" fan is 870 cfm and 10 amp draw, 16" fan is 1600 cfm and 14 amp draw. Electrical won't be an issue as I am rewiring the car. I just like the idea of redundancy of 2 fans. Thoughts?
