The MP fan I linked to is the Mopar Performance version. The other version shown earlier in the thread is a standard stock unit. The 5 blade fan moves more air because of the asymmetrical five blade design. Mopar put a lot of R&D into it and that's what they found. It also comes with a thermostatic clutch, which as already described to you, gets closer to lockup, the hotter temperatures get, in order to move the fan even more. They move a LOT of air. But as I stated, make sure you use a fan shroud.
