Is there a 140mm RAD fan that can outperform the CM Jetflow 140's?

Take a look at the specs

Fan Dimension 140 x 140 x 25 mm ( 5.9 x 5.9 x 1 inch )
Fan Speed 800~2000 RPM (PWM) ± 10%
Fan Airflow 54~122.5 CFM ± 10%
Fan Air Pressure 0.7~3.5 mm H2O ± 10%
Fan Life Expectancy 40,000 hours
Fan Noise Level (dB-A) 21~39 dBA
Bearing Type Rifle bearing
Connector 4-Pin
Fan Rated Voltage 12 VDC
Fan Rated Current 0.3A
Power consumption 3.6W

They came with my CoolerMaster Nepton 140XL, should I leave them, the sound is not too bad, so I could go for something as loud, but of course I'm asking what will outperform these quieter. So far I havent found anything that has as much static pressure and CFM. Can you?

Right, time for you to learn the one big rule of PC fans.

The manufacturers lie. The specifications that they give you for their fans are often complete rubbish and designed to make their fans look better than the competition, even if they are not. Therefore, we have to rely on independent testing to decide which fan is better than which.

Sadly, 140mm fan roundups or reviews are pretty hard to come by, so we'll run through the basics and I'll make some recommendations. On a radiator or heatsink, the priority is static pressure. The best 140mm fans for radiators I've ever had experience with are probably the NoiseBlocker Blacksilent fans and the Noctua A14s.

In relation to the CM Jetflow fans, the Noctuas are much quieter because of their lower RPM - they are rated for 1200 rpm whereas the Jetflows are up to 2000. I would go for the 1700 rpm Noiseblocker Blacksilent fans though, simply due to the fact that they are one of the quietest 140mm fans around at comparable speeds, thanks to the fact that the Gentle Typhoon fans (generally considered the best radiator fans) are only 120mm.

Conclusion: Go for the BlackSilent fans if you want to see similar performance at lower noise. I've tried both on an old 140 radiator and even at the lower RPMs, the Noiseblocker fan seems to beat the over-specified Jetflow.

What he said. Although I would add the phanteks 140mm fans are top performers from the reviews I have seen. At full speed of 1200 rpm they produce very reasonable noise and their pressure is somewhere in the 1.51mm range which is pretty good.
