How much fan power?

post #1 of 3
Thread Starter 
How do I have any clue as to how much CFM I actually need from my radiator fans? I plan on getting a low-CFM optimized radiator.

Pressure is a bigger factor than CFM. If you get a RX rad for example, anything over 40CFM is plenty to cool, but 60+ for better cooling. I personaly use TK-122s (55mm) on my RX360. Way overkill but cools well.

i would recomend either some Coolermaster R4s or Sythe Slipstreams for cost/performance leaning more so to the Sythe 1600rpm (http://www.newegg.com/Product/Produc...82E16835185059)

If you dont mind a tad louder (http://www.newegg.com/Product/Produc...82E16835185060) much better performance and cheaper if you order 2 or more.
