My cpu cooler fan has a 92mm fan and I'm looking to replace it. The current fan's air flow is rated at 51.1 MCF and the one I'm looking to use is 39.8 CFM. Now one is listed as MCF and the other is listed as CFM but, can I assume they are the same units? If they are, would that air flow loss be significant enough to cause problems?
I'm using it on an Athlon II X2 240 Regor 2.8GHz cpu, no overclocking and the most I use it for is for WoW and Rift. The reason for wanting to replace it is just aesthetics.
