About this deal

All but fan one beat their specs. Only the Antec True Quiet had a lower SPL than specified. The Noctua fans all matched or beat their CFM specs. The Noctua fans were adjusted so that their SPL profile does not match our hearing profile. In that, I judge they were successful: they have roughly the same SPL as comparable fans with similar airflow, but my observation was that the tone of the Noctua fans are more pleasing to listen to and easier on the ears and did not sound as loud as you would expect from their SPL’s.

The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. Its square shape and 140mm mounting holes (124.5mm spacing) make it ideal for use on watercooling radiators or as an upgrade for 140mm case fans. Featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 further improves the renowned quiet cooling performance of the award-winning NF-P14. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1500rpm to 1200rpm. Its performance-oriented 1500rpm top speed and comprehensive speed control options make the NF-A14 PWM an elite choice for users who strive to strike a perfect balance between excellent cooling capacity and superb quietness of operation, be it on watercooling radiators, on heatsinks or in case ventilation. A successor to the award-winning NF-P14 So with that being said, we will be creating two sets of configurations by using the NH-D15 heatsink. I personally use the anti-vibration mounts in all of my builds since they allow for a convenient and vibration-free installation of fans. The industrialPPC line is made entirely from fibre-glass reinforced polyamide which means it can withstand temperatures of up to 140°C. Noctua's industrialPPC fans are also water and dust proof certified which makes the NF-A14 industrialPPC fans suitable for operation in challenging environments.This heatsink kept up with the big boys. If you want a blow-down heatsink to cool your CPU and your RAM, the NH-C14S does a remarkable job. Additionally, there is room for most RAM, even with the fan in a pull position. monitor the temperature of the CPU and Prime95 (Large FFTs) will be used to deliver the full load to the CPU for 20 minutes. The other accessory set that Noctua has introduced is the NA-SRC7 which consists of three fully sleeved NA-RC7 Low-Noise-Adaptors. The purpose of a collection like this is to present you with data. It doesn’t matter what the absolute value of the measurements are, although these are reasonably accurate. What matters is that these measurements were all done on the same equipment. This allows you to compare them. The biggest difference between the NF-A14 industrialPPC fans and the regular Noctua fans is the introduction of the new three-phase motor design.

The fan’s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows to connect a second NF-A14 PWM fan to the same PWM fan header for automatic control. 6 years manufacturer’s warranty This is something that many reviewers take for granted when testing CPU coolers and believe it or not, it makes a world of difference.The results will be portrayed on a rather complex graph. You can either ignore the complexities and focus on the noise (in purple) and the unobstructed airflow (in red). But I think the other measures (through the rad, through the dust filter) may tell you things you want to know about each fan. Results of Testing
