Greater than one weekI was wary because they are suspiciously low priced, but the noctua quality is there. Would recommend.

> 3 dayIt’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.

> 3 dayMounts the same way as the CPU fan that comes with the cooler. One thing to note for those that are concerned with aesthetics, the rubber pads on this fan are slightly thicker than the ones one the ones that come with the cooler. Theres a slightly larger gap, but either thats intentional or I just happened to get some slightly thicker rubber pads. Otherwise, doesnt bother me too much.

> 3 dayThe hardest thing to do is keep CPUs and GPUs cool in a confined box. Add to this many GPUs dont activate the fans in a misguided effort to save energy by risking GPU card overheating. Many GPUs prevent or make it difficult to defeat these stupid GPU fan disabling energy saving features. The only answer is to fill the box with fans that keep air cooler by keeping air moving.

> 3 dayI will forever only use noctua from now on!! Ive had way better Temps with this than using corsair aio or even cooler master. This is a budget one but underload Im at 55c and thats with a ryzen 5 3600. I would also spend the extra 25 bucks for the e tra fan upgrade as well!! The thermal paste on this is amazing!! As someone that normally uses arctic mx-4 chances to switching to noctua thermal is a highly high possibility!! I absolutely love this cooler and will keep with it for future builds!!!

> 3 dayHad 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

Greater than one weekI 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

> 3 dayGreat add-on. Temp dropped by about 8C under load.

> 3 dayAdded this as a second fan to the NH-U12S Redux Cooler for an Intel i7-12700K CPU. Setup was straight forward as with other Noctua coolers/fans. This helped to drop the CPU temp about 2 degrees on average at idle/load. Good upgrade at such low price point.
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. |
