Greater than one weekI am using the Noctua NH-U12S Redux on a Ryzen 5 5600 overclocked to 4.65ghz. Running Cinebench R23 at full load I was topping off at 81-82c before adding this second fan and now under full load running the same test, I max out at 76-77c. Thats a 5-degree drop for only $18.18 with tax.

> 3 dayLo conseguí para un cooler alseye, al tener menos longitud el cable hizo más fácil la instalación, además del splitter en Y se le nota de muy buena calidad

> 3 dayThe Hype is real! Noctua products bring exceptional quality with low noise and dependable cooling! However, the size of the 120 mm fan is bigger than you may think. I’d recommend measuring clearances before buying them.

14-06-2025Muy 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.
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. |
