From Noctua's website about the NH-U9S:

Continuing the renowned legacy of Noctua’s award-winning NH-U9 series, the NH-U9S is a premium quality quiet CPU cooler in classic 9cm size. 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. Combined with its 125mm height, this makes the NH-U9S a highly versatile solution with excellent case, RAM and PCIe compatibility. The included NF-A9 premium fan supports automatic speed control via PWM for outstanding quietness of operation and a second, optional NF-A9 fan can be added for further improved performance in dual fan mode. Topped off with the trusted, pro-grade SecuFirm2™ multi-socket mounting system, Noctua’s proven NT-H1 thermal compound and full 6 years manufacturer’s warranty, the NH-U9S is a deluxe choice through and through.

The NH-U9S is the successor to the NH-U9B SE2 which is an asymmetrical cooler with five heatpipes that not only provides better cooling performance than the previous generation but also improves compatibility with mini-ITX and micro-ATX motherboards. The NH-U9B SE2 was 120mm deep with its two stock fans whereas the NH-U9S is asymmetrically built and measures only 95mm with its single fan thus providing better performance and compatibility at the same time. The improved asymmetrical design of the NH-U9S allows for a much lower profile and it also provides full compatibility with PCIe cards, be it on ATX, microATX or ITX.

Thanks to its 95x95mm footprint, the NH-U9S can fit in almost any HTPC case and this makes it great for mini-ITX builds. It does not overhang the RAM slots and this gives the user full access to the memory modules and guarantees 100% compatibility with tall heatspreaders. Noctua offers a six year warranty on their products and has an excellent customer service. If your fans every stop working or if you need a new mounting kit, they will send you a new one free of charge.

Noctua ships the NH-U9S with SecuFirm 2 mounting kit that makes the installation process a breeze. The NH-U9S comes with one 92mm NF-A9 PWM fan but Noctua has sent us an extra NF-A9 PWM fan to test with both one and two fan configuration. The original NH-U9B SE2 had four 6mm heatpipes while the NH-U9S has five 6mm heatpipes. The NH-U9S is constructed with a copper base, heatpipes, aluminum fins, soldered joints and nickel plating and weighs 524 g without the fan and 618 g with one fan installed. The nickel plated copper base plate measures 40 x 38 mm in size and the copper base plate measures 4.5mm thick and has a nickel-plated finish.

The NH-U9S has 43 aluminum fins and each fin measures 0.5 mm thick and are approximately spaced 1.7 mm from the next. The dimensions come in at 125 mm x 95 mm x 68 mm (H x W x L). The biggest change with the NH-U9S, design-wise, is the additional heatpipe and the increased fin count from 36 fins with the NH-U9B SE2 to 43 fins with the NH-U9S and I will talk more about this in the next page.

Another change that will make a big difference in cooling performance is the NF-A9 PWM fan. Noctua's NF-A9 PWM fan uses SSO2 bearing and is more efficient than the NF-B9 fan that shipped with the NH-U9B SE2 so you can expect better cooling performance while being much quieter. The NF-A9 PWM fan has a maximum rotational speed of 2000RPM while the older NF-B9 fan had a 1600RPM.

Packaging & Accessories

Noctua NH-U9S accessories and packaging

Here's the NH-U9S along with the NF-A9 PWM 92mm fan that Noctua sent me. Both products are packaged very well inside and you can definitely tell that these are premium products just from the packaging alone. Noctua utilizes their traditional color scheme on their packaging which we all have become used to.

Noctua NH-U9S accessories and packaging

The front of the box lists some of the features such as Award Winning NH-U Series, 100% RAM compatibility, 100% compatibility with PCIe cards on mini-ITX, PWM support and Low-Noise Adapter, NF-A9 92mm Premium Fan, PWM support and low-noise adapter, SecuFirm 2 Mounting System, compatibility with past and future sockets. On the left side you will find a short paragraph with details of the cooler and some of its features in multiple languages. Each of the features are detailed on the back of the box and the right side shows the specifications of the cooler and fan.

Noctua's packaging has always been top-notch and this time it's no exception. The accessories and mounting hardware are in a separate box while the heatsink and fan are in another. You will notice that Noctua uses internal cardboard boxes to protect the heatsink, fan and all the included accessories.
