NH-U9B SE2 Review

Even at default fan speeds the Noctua NH D9B SE2 does not generate much noise at all, and to the human ear it is hard to notice from a distance of one meter. Our recording equipment did measure around 22dBa. Moving to low noise and ultra low noise adapters brought further reward with dBa recordings of 16.8dBa and 16.2dBa respectively – clearly our equipment and testing room would need further improvement to measure more accurate dynamics at these settings.
Test verdict: "Once again Noctua have created a phenomenal cooler which is without a doubt one of the best solutions for this market we have yet to test on KitGuru." (Allan Campbell, KitGuru.net)

NH-U9B SE2 Review

While shorter in stature and overall bulk, the NH-U9B Special Edition delivers decent results. At stock speeds it allows the processor to run a full 10 degrees Celsius warmer than the NH-D14 that in and of itself is an accomplishment considering it ran within 5 degrees Celsius of the TRUE and NH-U12P. [...] This heatsink as delivered, is dead silent. If that's not silent enough, then you can install the Low Noise and Ultra Low Noise Adapters onto the NF-B9 fans to further drop the fan speed and noise. Priced at 55 bucks, this heatsink is not the most inexpensive, but quality components do come with a premium. As a heatsink that uses 92mm fans, it delivers performance that exceeds that of some of the other heatsinks I have used in the past and compares well with some of the cooling behemoths on the market.
Test verdict: "Much like its larger brethren, the NH-U9B Special Edition is a high quality heatsink with a ton of technology behind it. From the SSO bearings and Vortex Control Notches on the fans, to the build quality and darn-near universal SecuFirm2 mounting mechanism, to the NT-H1 thermal paste - it is all designed for a purpose. That purpose is to deliver excellent cooling capabilities, while keeping noise to a minimum. This goal, Noctua has been successful in achieving. I was impressed by its ability to hang as close to heatsinks that honestly are the cream of the crop." (Frank Dimmick, OverclockersClub.com)

NH-U9B SE2 Review

Noctua's NH-U9B SE2 has proven to be a decent performer. Its quality and bundled accessories set it apart from the rest of the competition. As usual, Noctua has bundled the cooler with easy to install mounting hardware for almost every current CPU socket along with a pair of excellent 92 mm fans, thermal grease, and tools to make installation a breeze. The included fans are near silent at normal 12V operation but there are also four voltage regulation adapters that, when utilized, drop the fan to 7V, or 5V to further decrease fan noise. Noctua's design also provides airflow for components around the CPU socket to aid in cooling of secondary heat sources. The cooler comes with a durable Nickel plated finish that is both functional and attractive to score in the looks department. Should you run into any problems, Noctua provides a six year warranty on all their coolers.
Test verdict: "Overall, the Noctua NH-U9B SE2 is a great choice for anyone in need of a fairly compact cooler seeking good cooling capacity while remaining near silent. It costs a few bucks more than other offerings but that can be justified after taking in consideration the quality put into all of Noctua's products." (Steve Harris, TechPowerUp.com)

NH-U9B SE2 Review

After going through the design and test review of the cooler there is no doubt that the cooler performs very well when it is put in its intended milieu. When paired with a processor running at stock speed, the cooler can keep the processor in a safe temperature envelope even without using any fans Even when the cooler is paired to an over clocked heat guzzling Core i7, it does not disappoint. The cooler was able to keep the processor under 80C. Remember that Linpack test generates massive amounts of thermal energy. Under normal operation the temperature would be much better.
Test verdict: "If you in the market for a cooler that would help you assemble a nearly silent HPTC you wont find a cooler better than the NH-9UB SE2." (Ali Tayyab, WCCFtech.com)

Desde que tenemos el gran honor de poder probar los disipadores de Noctua, sabemos que son sinónimo de tranquilidad. Los austriacos hacen un trabajo espectacular tanto con el diseño de los disipadores, como el de los ventiladores, esto último infravalorado por su gran importancia. El fabricante nos da 6 años de garantía y eso es confianza en su propio trabajo que deriva en confianza de sus clientes; el rendimiento de este disipador es indiscutible, aunque para equipos donde queramos más OC y bajas temperaturas, tendremos que acudir a modelos más grandes, como las series de 14 y 15, con ventiladores y estructuras más grandes. Pero este modelo está indicados para equipos compactos, como mini-torres o equipos multimedia, todo ello sin descuidar su misión, que es la de enfriar nuestra CPU, y lo hace realmente bien, con una sonoridad excelente. Lo mejor de todo es que no forzamos nuestra CPU, podremos tener aún menos sonoridad, al poder usar los adaptadores que frenan la velocidad de los ventiladores. Un 10 para su sistema de montaje, por supuesto, fácil de instalar, y no menos importante, fácil de quitar.

NH-U9B SE2 Review

We know Noctua for some of the best air coolers out there, but normally their coolers are quite large and are made for full-size PC builds. It is much harder to shrink down an air cooler and still have the same type of performance. Well it looks like Noctua was able to do that with the NH-U9B SE2 cooler. This makes it perfect for a small form factor gaming machine where you still want that great performance and might even be overclocking your processor. Now on the other hand if you wanted this cooler for say a HTPC setup it does come with both a low noise adapter and ultra low noise adapter which will slow the fan speed down making the cooler much more quiet.
Test verdict: "If you are looking for a smaller air CPU cooler this is definitely one that you should check out." (Bob Buskirk, ThinkComputers.org)

NH-U9B SE2 Review

Betrachten wir die harten Fakten, die unser Review geliefert hat, dann zeigt der Noctua NH-U9B SE2 eine wirklich sehr gute Vorstellung. Mit begrenzter Kühlfläche, dafür aber mit der Kraft eines potenten Lüftergespanns gelingt es dem kleinen Kühler, die sehr hohe Abwärme eines 125W-Phenom X4 zuverlässig und mit sehr geringer Geräuschentwicklung abzuführen - und das, ohne an die Leistungsgrenzen zu gelangen. Die Verarbeitung des Kühlers ist wie von Noctua gewohnt makellos, die Kühlrippen sind sauber gefertigt und entgratet, der Kühlerfuß sauberst poliert, die vernickelten Heatpipes tadellos eingepasst. Dass Noctua (zurecht) großes Vertrauen in die Qualiät der eigenen Produkte hat, zeigt sich in den üblichen, beeindruckenden sechs Jahren Garantie, die die Kühlerspezialisten auf den NH-U9B SE2 gewähren. Objektiv ist der NH-U9B sprichwörtlich der Kraftzwerg unter den Kühlern und sicherlich auch der König der kleinen Tower-Kühler, sei es bei der Verarbeitung oder der schieren Kühlleistung.
Test verdict: "Noctua zeigt mit dem NH-U9B, dass auch aus begrenzter Kühlerfläche bei Verwendung hochwertiger Materialien, einer durchdachten Konzeption und makelloser Verarbeitung ein beeindruckendes Maß an Wärmeabfuhr erzeugt werden kann. Mit der Kraft des leisen und gleichzeitig leistungsstarken 92mm-NF-B9-Pärchens auf dem Kühlkörper gelingt es dem Kühler aus Österreich, auch hitzköpfige CPUs zuverlässig und leise zu kühlen ohne dabei an die eigenen Grenzen zu stoßen. Insgesamt bietet Noctua mit dem NH-U9B einen echten Kraftzwerg unter den kompakten Towerkühlern an, der gute Kühlung auch in beengtere Gehäuseverhältnisse zu bringen vermag."

Can the cooler be installed turned by 90° on AMD sockets?

In order to install the cooler turned by 90° on AMD, the optional NM-A90 kit is required.

Is the high weight dangerous for the CPU or socket?

No. Noctua coolers possess an extremely reliable SecuFirm™ mounting system. Thanks to the screw connection with the backplate on the rear side of the motherboard, the exceedance of the weight recommendations by Intel and AMD common among high-end coolers is completely unobjectionable.

Is it possible to mount fans with a greater height than 25mm?

Yes. The fan mounting clips grip to the screw holes in the lower edge of the fan frame and hence work with all fans regardless of their height. However, problems with the mounting of the fan can occur due to other parts within the case or fans with special frame designs, where the clips can't grip to the screw holes in the lower edge of the frame.

NH-U fan mounting

Is it possible to run two fans at a time?

Yes. Using the 4 supplied fan clips, you can mount two 120mm fans on the NH-U12(F/P) and two 92mm fans on the NH-U9(F/B).

Should the fan be mounted sucking away from the heat-sink or blowing onto the heat-sink?

Please install the fan blowing onto the heat-sink.

NH-U Airflow

If you're using two fans, please install them so that one blows onto the heat-sink and the other sucks the air away from the other side.

On which side of the heat-sink should the fan be installed?

Please install the fan so that the hot air can be disposed as good as possible either through the rear case fan (Airflow Option 1) or through the power supply (Airflow Option 2).

NH-U Airflow

Is it possible to cool my CPU without a fan (passive) using Noctua coolers?

Noctua coolers weren't originally designed for passive operation although the cooling performance is sufficient in many cases. Unfortunately, it is impossible for us to indicate whether a certain CPU can or cannot be cooled without a fan, as this depends on various factors such as case temperature, case ventilation or the orientation of the socket. Generally, we recommend using a fan in the first instance and then lowering RPM while constantly monitoring the temperature.

How to install the fan using the supplied steel clips?

First hook the clip into the notch of the heatsink:

Vibration Compensators Installation

Then hook the endings of the clips into the mounting holes of the fan:



Vibration Compensators Installation

What can I do if the fan blocks my RAM or chipset cooler?

In order to increase clearance, you can easily move the fan up a few fins as show below:

Vibration Compensators Installation

Can I use Noctua fans on my fan controller?

Our fans are compatible with the vast majority of fan controllers on the market. However, there is a compatibility issue with a few models such as the Zalman ZM-MFC2 and Bitfenix Recon, which apply Pulse Width Modulation (PWM) on the 12V line and use an unfavourable PWM carrier frequency. This can create an oscillation when used with certain fans, which will result in the fan speeding up and down. We therefore recommend not using the Zalman ZM-MFC2 or Bitfenix Recon with our fans.

My fan doesn’t spin when I start up the PC - is it faulty?

If you've connected the fan directly (or using the supplied Low-Noise or Ultra-Low-Noise-Adaptors) to your mainboard, it's possible that the mainboard's automatic fan controller doesn't provide the required starting voltage due to the low CPU temperature. Please verify whether the fan starts spinning at higher CPU temperatures, remove any Low-Noise or Ultra-Low-Noise Adaptors, deactivate your mainboard's automatic fan controller in the BIOS or connect the fan directly to the power supply using the supplied 3:4-pin adaptor.

Can I run Noctua 3-pin fans on 4-pin PWM connectors and use my mainboard’s automatic fan controller?

You can simply connect our fan's 3-pin connector to the 4-pin PWM sockets of today's mainboards so that the fourth pin that transmits the PWM signal is left blank (due to the shape of the connector, there's no danger of reversing polarity). Some mainboards (e.g. current Gigabyte models) are capable of controlling fans not only via PWM, but also by adjusting the supplied voltage. In some cases, this may require you to change BIOS options like "Fan Control Mode" from "PWM" to "Voltage" or "Analog". Please consult your mainboard's manual in this regard. However, some mainboards use an "auto" setting by default that automatically chooses PWM or voltage based regulation according to the connected fan. Automatically controlling the fan speed may not possible on mainboards that pulse the power rather than lowering the fan voltage.

PWM PWM

How can I check whether my case is wide/high enough for the cooler?

In order to check whether the cooler isn’t too high for your case, please measure the distance from the motherboard tray to the side panel (tower cases) or top panel (desktop cases). If this distance is bigger than the height of the cooler + 15mm (mainboard spacers + mainboard + CPU), the height/width of your case should be sufficient.

Help, the base of the cooler doesn’t make contact with the CPU / there is no contact pressure!

Please verify that you have installed the fastening brackets correctly:

Fastening Brackets

Is the cooler compatible with LGA1366 mainboards for Xeon 5500?

Due to the custom NM-I3 backplate, the cooler can not be used on mainboards that have a backplate with screw threads for CPU cooler installation (such as the Intel reference backplate for Xeon 5500). Please choose our NH-U12DX 1366 for these mainboards.

1366 compatibility

My mainboard has more than one set of mounting holes. Which one should I use?

Please always use the standard set of mounting holes that's compliant with your socket type (e.g. 75mm LGA1156 hole spacing on LGA1156 sockets) and parallel to the sides of the socket. Don't use mounting holes which are rotated in relation to the socket.

1366 compatibility

I can't open the socket due to the mounting bars!

Please first loosen one of the two thumbscrews that hold the mounting bars in place. Then untighten the second screw so that you can swivel the mounting bar and open the socket. Depending on the position of the mounting bars, you may need to swivel both.

Open Socket

Open Socket

Does the package include a backplate for AMD AM2(+)/AM3(+)/FM1/FM2(+)?

No. As most AMD mainboards come with a stock backplate preinstalled, the cooler doesn’t include an AMD backplate. If your mainboard doesn’t have a backplate, please contact our support team at support@noctua.at.

amd backplate

The supplied y-cable is missing a wire at one of the two connectors, is it faulty?

No. As mainboards can process only one rpm-signal per fan header, it would cause problems if the cable transmitted rpm-signals of both fans. For this reason, one of the two connectors does not have an rpm wire and only the fan on the other connector will transmit an rpm signal. Automatic speed control of both fans will work independent from the second fan’s rpm signal.

The fan doesn’t start with the Ultra-Low-Noise Adaptor (ULNA)!

Unfortunately, many Gigabyte mainboards use a special control circuit that can lead to start-up problems in conjunction with the Ultra-Low-Noise Adaptor (ULNA). This control circuit remains active even when automatic fan control is disabled in the BIOS. In these cases, please use the fan without the ULNA or connect it directly to the power supply (or an external fan controller) in order to ensure reliable operation with the ULNA.

I get a CPU fan error despite the fan is running!

Some mainboards display a CPU fan error when the fan speed falls below a certain threshold, e.g. 900rpm. If you want to run the fan below this speed (e.g. using the supplied U.L.N.A.), please adjust the threshold in the BIOS or disable CPU fan error warning.

Is the mounting system compatible with LGA1155?

Yes. LGA1155 uses the same hole spacing as LGA1156, so the same SecuFirm2™ mounting system can be used.

How can I check whether my AMD mainboard has a standard AMD backplate that’s compatible with the SecuFirm2™ mounting system and how should I proceed with the installation?

The SecuFirm2™ mounting system requires a standard AMD backplate (either plastic or metal) with screw threads as shown on the pictures below. These backplates are pre-installed on the rear side of most AMD mainboards (see first picture below) and fixed to the retention module with four screws (see second picture below). If your retention module is fixed with plastic bolts instead of metal screws, please contact support@noctua.at in order to obtain an appropriate backplate.

In order to proceed with the installation of your Noctua cooler, please remove the four screws and the retention module but keep the backplate in place so that you can see the screw threads from the top side of the motherboard (see third picture below). You can then proceed with the installation of the SecuFirm2™ mounting kit as described in the manual (see fourth picture below).

Is the cooler compatible with AMD AM3+ and FM1?

As the hole spacing for CPU cooler installation on AM3+ and FM1 is the same as on AM2, AM2+ and AM3, the cooler is fully compatible with AM3+ and FM1 out of the box and doesn’t require any modifications or upgrades.

Is the cooler compatible with the Intel LGA2011 socket and Asus X-socket™?

The cooler doesn’t come with LGA2011 mounting hardware out of the box, but it can be upgraded to support LGA2011 via the NM-I2011 mounting kit.

Please also note that the cooler is fully compatible with Asus Rampage IV series LGA2011 motherboards that feature Asus X-socket™. Asus X-socket™ models use an interchangeable backplate that makes it possible to install LGA1366 heatsinks, so the cooler is fully compatible with these mainboards out of the box and does not require any upgrades to be installed.

Asus X-socket

In order to install the cooler on Asus X-socket™ mainboards, please first remove the mainboard’s LGA2011 backplate and install the LGA1366 backplate supplied with the mainboard instead (see the mainboard manual for detailed instructions). Then install the Noctua cooler as described in the supplied installation manual for LGA1366. In case you’ve lost the printed installation manual, you can download it here.

How should I clean my Noctua cooler?

Dust: Fans and heatsinks inside computer cases tend to accumulate dust over longer periods of usage. In order to maintain maximum performance, please clean your fan and heatsink regularly. For cleaning, please first remove the fan from the heatsink and clean it using a duster, slightly moist tissue or canned air. Please be careful not to use too much force in order to prevent any damage to the fan. Please do not use a vacuum cleaner as this may apply excessive force to the fan and do not put the fan under running water as water residues inside the motor may lead to short circuits. Please also note that the fan is not designed to be taken apart by the user. Removing the impeller from the frame will break the sealing of the bearing and results in a loss of warranty. Before reinstalling the fan, clean the heatsink itself with a duster or vacuum cleaner. Finally put the fan back on and connect it to your motherboard fan header or fan controller.
Thermal paste residues: Whenever you take off the heatsink from the CPU, we recommend to clean the CPU as well as the base of the cooler before re-applying thermal paste and re-installing the cooler. You can either just wipe the base and the CPU clean with a dry, lint-free tissue or, for more thorough cleaning, use a lint-free tissue moistened with either a mild solution of washing-up liquid or isopropyl alcohol. Do not put the cooler or CPU under running water. Note that both the base of the heatsink and the CPU should be dry, free from residues of thermal compound and free from grease before re-applying thermal paste and re-installing the cooler.

Is the cooler compatible with AMD FM2+?

As the hole spacing for CPU cooler installation on FM2+ is the same as on AM2, AM2, AM3(+), FM1 and FM2, the cooler is fully compatible with FM2+ out of the box and doesn’t require any modifications or upgrades.

Which Noctua coolers are compatible with LGA1150?

The mounting is identical on all LGA115x sockets (LGA1150, LGA1155, LGA1156). The following coolers are thus compatible with LGA1150 out of the box and don’t require any upgrades in order to be used on this platform: NH-C12P SE14, NH-C14, NH-D15, NH-D14, NH-L12, NH-L9i, NH-U14S, NH-U12S, NH-U12P SE2, NH-U9B SE2. In addition, all older models which have been upgraded with the NM-I3 kit can also be used on LGA1150 without any further upgrades.

The following coolers can be made compatible to LGA1150 using the NM-i115x Upgrade-Kit and are eligible for Noctua’s free mounting kit offer: NH-C12P, NH-U12, NH-U12F, NH-U12P, NH-U12P SE1366, NH-U9, NH-U9F, NH-U9B.

The following coolers can be made compatible to LGA1150 using the NM-i115x Upgrade-Kit but are not eligible for Noctua’s free mounting kit offer: DX-Series Xeon coolers, NH-D14 SE2011.

The following coolers are mechanically incompatible with the NM-i115x Upgrade-Kit and can not be made compatible with LGA1150: DO-Series AMD Opteron coolers, NH-L9a.

I’ve used all the NT-H1 thermal compound that came with the cooler, can you send me more?

Please kindly note that the NT-H1 thermal compound supplied with our coolers is a consumable item so our manufacturer’s warranty does not include providing additional thermal compound. You can purchase NT-H1 from our resellers.

Which sockets are supported or can be supported using upgrade kits?

Please refer to our socket compatibility chart.

Why doesn't the base of Noctua coolers have a polished, mirror like finish?

As most of today's PC enthusiasts use high-viscosity thermal compounds, the contact surface of Noctua coolers is optimised for use with this type of pastes. The micro-grooves at the contact surface ensure that high-viscosity thermal compounds are dispersed to a uniform thin layer across the whole contact area and that no air pockets remain between the cooler and the CPU. With a polished, mirror like surface, the risk of uneven dispersion is much higher. As too thick layers of thermal paste and air pockets drastically deteriorate heat transmission, the micro-grooves are is of vital importance to the overall cooling performance of Noctua coolers when used with today's high-viscosity thermal pastes.

How to remove the base protection cover?

Noctua CPU coolers are shipped with a plastic protection cover at the bottom side of the cooler, which protects the contact surface against scratches and other damage.

The base of Noctua CPU coolers is made from hard-wearing nickel plated copper, so there's nothing to worry about if you buy a Noctua cooler from second hand or if your cooler didn't come with a protection cover. Please proceed with the installation as explained in the manual.

Can the cooler be installed turned by 90° on AMD sockets?

No. The new SecuFirm2™ mounting system for AM2, AM2+ and AM3 uses the same standardised hole spacing as the Intel system and thus allows for a much easier installation, but the cooler cannot be installed turned by 90°.

Should I take the cooler off before transporting my system?

Due to the low weight of the cooler, it is not necessary to take it off for transport.

Are there any concerns using Noctua CPU coolers on Intel Skylake (LGA1151) CPUs?

Our SecuFirm2™ mounting systems undergo comprehensive compatibility tests before being approved for new platforms. We have neither detected any problem with regard to the Intel LGA1151 platform (“Skylake”) during these tests nor have we received any reports from our customers, sales partners and system integrators that would indicate any possible issue. Our SecuFirm2™ mounting systems (with the exception of some compact L-type models) rely on coil springs to create the required contact pressure, which gives a certain flexibility both with regards to tolerances in stackup height and shocks or other forces. Compared to spring-less mounting systems, which exclusively rely on the bending of the mounting brackets in order to create contact pressure, this allows to reduce the mechanical stress on CPU, socket and motherboard and thus helps to prevent possible damage from excessive forces. However, as it is not possible to reliably calculate or control the forces that act upon a system during transport (e.g. in shipping), we generally recommend, due to safety reasons, to take off coolers with a total weight of more than 700g (incl. fan).
