> 3 dayThis was really easy to install and mounted on to my Noctua D15s fan easily! Helped reduce temperatures of my cpu about 1-3 degrees which was nice. Highly recommend this one!

Greater than one weekOverall 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.

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

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 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.

> 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 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 dayDoesnt cost much more for the second fan upgrade and makes a nice difference!

> 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.
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. |
