> 24 hourHad to modify my original fans clips to work with this fan but it fits tight, runs quiet, and keeps my processor cooler than original cooler master when it was new

> 24 hourThis is a great fan that runs silent and keeps my PC cool. I actually ordered it to replace another brands fan on my heatsink and was able to rig it to fit on that heatsink. Im very satisfied with this fan.

> 24 hourIt’s like the first fan, the silicone brackets for the sides of the fan are a bit larger, so the clips have a harder time of going on but once you get it on its good. It comes with a Y-plot 4 pin connector and 2 extension cables for it as well. Great buy, worth it. Dropped temps well.

> 24 hourI bought it thinking it was a second fan upgrade for the redux cooler, but not only is the fan different but the noise reduction pads are bigger than the stock ones. either way its a good purchase just be ready to put it on patiently

> 24 hourMounts great to NH-D15 if memory slot issues cause a 140mm fan to be too big. In my case I could not get the door of my PC installed because the 140 was to tall. This 120mm allowed to to install the case door.

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. |
