The KEY thing to Cooling is PRESSURE.. cfm rating is not as important as the amount of pressure..
because pressure is ultimately what will move warm air.. CFM rating means nothing.. manufacturers can literally put anything they want on the box..
CFM and SP can be arbitrary. And you need to balance the SP and CFM based on your radiator. You should have at least 1mmHg2 for most radiators, but some will require a higher CFM for best performance, others require higher SP and can get away with a 40CFM fan. From what I remember, the H60 is a lower FPI rad that does better with a higher CFM fan with a decent SP than a fan with higher SP and mediocre CFM.
that's right, that's why I have corsair so fans for my pc.
they are fine, but I want something better
What size do you need? Thermalright, Noctua, and BeQuiet! all make fantastic performing and also quiet fans. CoolJag Everflows (certain models) are quite good for the money as well.
