i was running at 210f with one 1650 cfm 14" fan and a milodon water pump on my 455, well i grabbed a 2950cfm hp prema cool fan also 14" to go next to it, and wow!!!! i dropped from 200-215 to 160-170, just like that
funny thing is both fans are 14" perma-cool but the 1650 stanard cost 103 in jegs and the high performance model only cost 94 for a 2950, why oh why didn't i buy the hp to start with.
now running 4600 cfm amd she likes it
