FAQ:

Q: What makes the Noctua nh-u9s so special?

A: Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system and Noctua’s proven NT-H1 thermal compound, the NH-U9S is a deluxe choice through and through. The NH-U9S stems from Noctua’s award-winning NH-U9 series.

Q: Is the nh-u9s compatible with LGA 1366?

A: Low-Noise Adaptor (L.N.A.) Complying with the open SecuFirm standard, the NH-U9S can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided by Noctua free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets. .

Q: What does the nh-u9s include with the fan mounting clips?

A: The NH-U9S includes an extra set of fan mounting clips for users who want to achieve even better cooling performance by adding a second, optional NF-A9 PWM fan in order to create a push/pull setup. Using the y-cable supplied with the NF-A9 PWM retail fan, both fans can be connected to one CPU fan header.

Q: What are the benefits of the nh-u9s?

A: Its asymmetrical design with 5 heatpipes not only provides even better cooling performance than the previous generation but also improves compatibility: Thanks to its 95x95mm footprint, the NH-U9S clears the RAM and PCIe slots on all Intel and most AMD based mainboards, including µATX and ITX.
