Previously used 120mm Cooler Master Jetflow & Sickle flow fans, they are good enough to dissipate heat from Crossfire GPU's,
But the problem was they made a lot of noise and vibration, efficiency was down when RPM was adjusted to low noise.
Changed it to Noctua 140X2, when one Jetflow fan broke down within a month of purchase & received no response from Cooler Master in four days after lodging complaint.
Airflow is 114CFM compared to Jetflow's 95 CFM,
Absolutely no Vibration on full RPM

Good stuff, quiet, great build quality, and even better support ... i picked this up for my desktop keeping temps cooler ....thanks to flipkart for the super fast dilivery.

If ur looking good Quite silent yet with Good CFM then please do not look elsewhere.
