So last year I had a BM fan, it did alright but the temps would climb in heavy traffic, over the winter I purchased two twelve inch fans that were supposed to flow 2100cfm each but I just took the car out tonight and it seems to heat up much quicker in traffic than the BM did. I dont have much clearance because I have an 8 rib blower setup and the ford racing radiator. So i was wondering if I could but the BM back on and put one of the small ones in the front as a secondary pusher fan I know they would overlap a little but would that be a problem?
