> 3 dayDid bring down my temps from the usual 70c on load in my hp omen case to 53c on my meshify c case that had 3 intake and 3 exhaust fans. Had in a push/pull config on the cpu..

> 3 dayI had to try this with a new Noctua cooler as the 4 heat pipe with 2 120 mm fans allowed my 5900x to hit 93c under heavy loads, which would cause it to throttle down. This gave me an 8-10c drop, keeping me under 90, I wont do water as I dont like the drawbacks to water cooling.

> 3 dayOverall great product but keep in mind that it does not come with screws, unless you have mounting screws of your own this is not a problem. U feel like a set of screws should’ve been added to give the buyer a more flexible spectrum of where they could place this fan. Fan itself is a 5 star, kit would be like a 4 1/2 would definitely buy again if needed.

Greater than one weekCant go wrong with this one. High quality product for a great price. Ease of installation depends on how tight of a fit your case is, but its the same thing as the fan that comes with the cooler.

> 3 dayDropped my temperatures a further 4 degrees Celsius compared to my single fan unit. Highly recommend

03-06-2025I 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

Greater than one weekWorks as expected.

> 3 dayUsing a second fan for a push/pull configuration. Not sure if it makes much difference, but worth a try

> 3 dayIts greats and actually works but its a little loud and its a pain to install. Is it worth it though? My answer is absolutely. Also use the noise adapters since they actually do reduce noise.

> 3 dayA simple but effective and easy to use add in kit. Well worth the money for the boost in performance.
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. |
