Would these fan clips work for the u12p? I have the heat sync but no fan clips. Since im not the original owner I cannot get them from noctua.

Since this was designed as an add on fan for the Noctua NH-U12S redux cooler, the clips will be compatible with the other Noctua NH-U12S coolers. Diagrams of these coolers can be found at the Noctua website showing the exact dimensions.

Does the fan have a cfm rating? (i don't see cfm on noctua.at specs)

This is a replacement part for the u12s cooler which commonly has a fan of a cfm rating of 70.60 so I'm guessing that's it

Hi,does it work with cooler master hyper 212 evo ??

yeah but you'll need the brackets that came with the 212

2-3*C cooler. Worth the money, especially when you look at the price of the fan on it's own.

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!
