Not quite 20% cooler ;)
2-3*C cooler. Worth the money, especially when you look at the price of the fan on it's own.

Worthwhile Accessory
I picked this up to add to my NH-U12S Redux air cooler. It will only drop temperatures a few degrees more, but I had room for it in my case so wanted to add it. As you would expect from Noctua, it arrives in a nice box and comes with a fan splitter cable, two low noise adapters and the metal grips to attach the fan to the cooler. The fan fits perfectly and isn't too loud either. Recommended.

Great addition.
So impressed with the quietness of NH-U12S redux Cooler I added this upgrade to ensure a well cooled CPU which had a reputation of running a tad warm. The result is really impressive with a really cool CPU and super quiet installation.

2nd fan didn't make any difference
It is Noctua quality, it's quite. I added it to existing Noctua radiator but the 2nd fan didn't make any difference in my case.

Very Quiet
Fiddly to fit but that's mainly due to the size of my case. Very quiet in use and the temperature have dropped by 5c there about.

Es una excelente opción para mejorar la refrigeración en mi PC. Su instalación fue rápida y sencilla, y lo que más me sorprende es lo silencioso que es, incluso a altas velocidades. La calidad de construcción es evidente; se siente robusto y bien diseñado. Además, ofrece un buen flujo de aire, manteniendo las temperaturas de mis componentes en niveles óptimos. Me gusta que viene con todo lo necesario para la instalación y su diseño clásico en color gris lo hace lucir bien en cualquier configuración. Sin duda, lo recomendaría a cualquiera que busque un ventilador eficiente y silencioso. ¡Gran compra!

Used these in my SFF build. They are very quiet, they look pretty good and they even come with rubbers. Only thing to note is that the cables are pretty short, so watch out for that when chosing these.

Il kit di aggiornamento Noctua NA-FK1 redux è un must per chi possiede il dissipatore NH-U12S! Con la seconda ventola NF-P12, ho notato un miglioramento significativo nelle prestazioni di raffreddamento, riducendo le temperature di 1-3°C. La qualità costruttiva è eccezionale e il funzionamento è quasi silenzioso, grazie agli adattatori a basso rumore inclusi. L'installazione è stata semplice e veloce, e ora il mio sistema è più efficiente e stabile anche sotto carico elevato. Consiglio vivamente questo prodotto a chiunque desideri ottimizzare il proprio PC! Un acquisto da 5 stelle!
