Great but pricey
Noctua fans never disappoint when it comes the performance, noise and build quality. Better air flow and much quieter than the stock fans in my Fractal R5. They're pricey but imo they're worth it.

Quietest 140MM Fan I've ever used / heard.
Swapped my case to Antec Flux and fit 4x NF-A14x25 G2 PWM Sx2-PP at the same time, 3x at the front and 1 in the rear, used 1 NF-A14x25 for PSU shroud intake, really impressed with how you can't hear these fans under 800 RPM, even at 400 RPM the amount of air they move is impressive, they can be heard once you start increasing the RPM however with the amount of air they move I don't have to have them above 600 RPM.As in Noctua fashion you get a very nice unboxing experience and they come with all the usual accessories you'd expect, one thing to note is by default the fans ship with the radiator rubber gasket preinstalled unlike previous Noctua fans that come with the 4x corners preinstalled so you'll have to swap them over.Expensive when compared to other fans on the market however I'm more than happy with my purchase.

Inaudible above my system hum at 55%.
I like the performance of these fans. I am after mostly quiet but occasional power. The amount of research & development that went into these fans is impressive. I used them to replace my NF-A14s when one of them died (within the six year warranty). I have the same level of system noise (aka none with headphones on) and my coolant temperature is lower; which with modern CPUs and GPUs means more performance. I have my fans set to ramp up @36'c water temperature (summer time) and have 10'c to go, at virtual silence. I bought a spacer: Noctua NA-IS1-14 Sx2; and have used it on one of my 3 140mm radiator fans as space permitted. I've watched a youtube review which said that the fans can perform better with the spacer in this pull scenario with a radiator.Did I mention the six year warranty?

The best 140mm fan (shame about the colour)
Until the Chromax Black variant arrives this is the best 140mm fan you can buy. It looks ugly. The colours are awful. But the airflow, pressure and cooling can't be beaten when taking into account the low noise.

Extremely quiet fan
Used this as an intake case fan, linked to GPU fan speed, to ensure optimal airflow when GPU under load. Wanted a quiet fan as the GPU instructs it to run at up to 90%. Even when running at 1500rpm, this fan is so quiet it is barely noticeable over the noise of the GPU fans (which are reasonably quiet anyway), and the sound is a pleasant "rushing wind" sound rather than a "whine".

Overrated
Good build quality, quiet motor.But not suitable as a case fan - tested as exhaust in Dan Cases C4-SFX and it was much louder than be quiet! Silent Wings Pro 4. Extremely loud turbulence when placed against a perforated side panel.Add to that, they can't go beyond 1'500rpm (not that you'd want to!)Very disappointing for the price.
