I use the stock Pentastar fan with a C & R Racing radiator. The owner designed this system for his own 6.4 liter Hemi. I was intent on changing my fan and he told me these brushless Pentastar fans are some of the most powerful on the market.The t-stat fully opens about 203* & my fan kicks in at 212 - 215*. That's about as good as a Semi will cool especially here in the altitude pulling these long mountain passes. The system works well.and uses the stock overflow bottle.
