> 3 dayNice addition to my Noctua NH-U12S Redux and keeps my i5-12600k plenty cool. A little difficult to add on but thats because I clipped on while heatsink was still in my system and its a tight fit for my hands, but a great product.

Greater than one weekThis 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 dayMuy buen producto, llego a tiempo, lo ocupo con un i5 11400 que suele ser un procesador muy caliente y las temperaturas no pasan los 50°c y mientras no se ocupa sus temperaturas bajan hasta 20°c lo cual ed genial, recomiendo ocupar una configuracion de 2 ventiladores con el kit extra para una refrigeracion mas eficaz y menos ruidosa.

Greater than one weekI 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!!!

Greater than one weekThis cooler in combination with the 2nd fan upgrade kit dropped my CPU temps from almost 80 degrees to 55 at most under high stress. They have been absolutely amazing and rarely even need to go above half of their potential RPM making my system as a whole way quieter than it was before. Not to mention the price for what youre getting if you do take the bundle, definitely worth the price, no more stutters no more hot CPU wonderful product

> 3 dayGreat upgrade to an already great cooler. This keeps my Ryzen 9 5900x nice and cool.

> 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 dayVery happy with purchase. Love the Noctua products. Great and reliable products. In the last 3 years, I have only purchased Noctua fans and CPU coolers on all of my builds..
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. |
