Coolermaster 90CFM 19dBA 2kRPM fans

[IanY]

Here... 31 pages of forum thread on a fan, just to conclude that its ratings are bogus and its radiator performance is weak.

This is an elementary review of the 70 cfm version

I dun really find it noisy but I find the airflow rather "weak" as compared to my TT BigTyp VX's fan.
After replacing 1x case fan from the NZXT Alpha & the TT BigTyp VX cooler while the TT fan replaced the original exhaust fan of the NZXT chasis, I expect to bring the CPU temp down .
But I was disappointed.
On idling, it showed improvement of 2'C but onload it's few deg higher than previous setup.
Think tonight I'll have to swap the exhaust fan & the CPU fan, confirmed the TT one has a stronger airflow though it's rated 86cfm. Wonder how & base on what CM rate it as 90cfm?
