Noctua NA-FK1 Redux, Second Fan Upgrade Kit for NH-U12S Redux Cooler

> 3 dayThis kit is suppose to be a secondary fan to the NH-U12S Redux Cooler. First, let me say that this is my second Noctua purchase. Their fans and accessories are top notch. They are the ROLEX of the PC Fan industry and dont skimp on quality of their products. The fan upgrade however is not what I expected, the fan blades are entirely different than the one that comes on the Redux cooler. Although, the same size, different blades and the rubber grey sound dampeners are even twice as thick as the fan that comes with the Redux. Not sure if this was a mistake or if Noctua intentionally allowed this variance in product types, but the sound dampener on the upgrade fan makes it very difficult to install and the noise from the second fan is more pronounced which I can tell between the original and upgrade fan.

> 3 dayThis was really easy to install and mounted on to my Noctua D15s fan easily! Helped reduce temperatures of my cpu about 1-3 degrees which was nice. Highly recommend this one!
The NA-FK1 is a second fan kit for the NH-U12S redux CPU cooler. Upgrading it to a push/pull-style dual-fan setup makes it possible to further improve cooling performance or to reduce noise levels by having two fans running at lower speeds. The kit includes a second NF-P12 redux-1700 PWM fan, anti-vibration pads, fan mounting clips, a 4-pin PWM y-cable as well as two Low-Noise Adaptors – everything you need to boost the efficiency of your NH-U12S redux!

Enhanced cooling performanceAdding a second NF-P12 redux-1700 PWM fan to the NH-U12S redux makes it possible to further improve cooling performance by around 1-3°C, depending on the application. As a rule of thumb, the gains are bigger the higher the heat load, so the NA-FK1 is particularly attractive for higher-end CPUs, extensive turbo use or overclocking. |
NF-P12 redux-1700 PWMThe NF-P12 redux-1700 PWM fan included with the NA-FK1 is the same high-quality unit that comes pre-installed on the NH-U12S redux CPU cooler, so it’s a perfect match for a push/pull-style dual-fan setup. Supporting PWM for automatic speed control, it can run near silent most of the time and provide massive performance when necessary. |
Lower noise levels and acoustic fine-tuningThe NA-FK1 can not only be used to enhance cooling performance, but also to lower noise levels: by letting both fans run at reduced speeds, either via automatic PWM control using the supplied y-cable or via the included Low-Noise Adaptors, the NH-U12S redux can operate more quietly while maintaining the same level of performance. |
