Having received more than 100 awards and recommendations from international hardware websites and magazines, Noctua’s compact NH-L9x65 has become a standard choice among 65mm tall low-profile coolers. The SE-AM4 version is a dedicated special edition for AMD’s AM4 (Ryzen) platform featuring the latest SecuFirm2™ mounting system for AM4. Topped off with the renowned quiet NF-A9x14 PWM 92mm fan, Noctua’s proven NT-H1 thermal compound and a full 6-year manufacturer’s warranty, the NH-L9x65 SE-AM4 forms a complete premium-quality solution for AM4-based ITX builds and HTPC systems.
Please note that being a dedicated special edition for AM4, the NH-L9x65 SE-AM4 comes with AM4 mounting hardware only, and that for this cooler, Noctua cannot provide free mounting kits for other current sockets such as LGA115x or LGA2011. For the NH- L9x65 SE-AM4, these mounting kits can only be purchased in retail or online shops (NM-i115x for LGA115x and NM-I2011 for LGA2011). Future mounting upgrades will be provided free of charge as usual if technically possible.

Caution: The NH-L9x65 is a highly compact low-profile quiet cooler designed for use in small form factor cases and HTPC environments. While it provides first-rate performance in its class, it is not suitable for overclocking and should be used with care on CPUs with more than 95W TDP (Thermal Design Power). Please consult our TDP guidelines to find out whether the NH-L9x65 is recommended for your CPU.

Award-winning NH-L9x65 cooler

Award-winning NH-L9x65 cooler

Tens of thousands of enthusiast users all over the world swear by the NH-L9x65’s quality and performance. Recommended by more than 100 international hardware websites and magazines, it is renowned for being one of the best sub-70mm low-profile heatsinks on the market.
Dedicated special edition for AM4

Dedicated special edition for AM4

The NH-L9x65 SE-AM4 brings the NH-L9x65’s signature quiet cooling performance to AMD’s new AM4 platform. With its highly compact design and low profile, it is ideal for cooling lower TDP AM4 CPUs in HTPC or Small Form Factor cases.
65mm low profile

65mm low profile

Due to its compact heatsink and the 14mm thin NF-A9x14 low profile fan, the NH-L9x65 stands only 65mm tall (the same height as low-profile expansion cards), which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer limited clearance for CPU coolers.
100% RAM compatibility

100% RAM compatibility

Being 95mm wide, the NH-L9x65 SE-AM4 complies with the AMD AM4 socket’s keep-out zone. This means that it won’t cause issues with chipset coolers and doesn’t overhang the RAM slots, making it fully compatible with tall memory modules.
100% compatibility with PCIe cards on mini-ITX

100% compatibility with PCIe cards on mini-ITX

Many mini-ITX mainboards have the PCIe slot sitting close to the socket zone. While larger coolers with 120mm or 140mm fans that exceed this zone may block the PCIe slot, the compact NH-L9x65 provides full compatibility with PCIe cards.
Easy access to near-socket connectors

Easy access to near-socket connectors

Many low-profile coolers use larger fans or heatsinks in order to achieve sufficient cooling performance, but by protruding over the socket zone, they make it difficult or even impossible to reach near-socket connectors on tightly packed ITX mainboards. Thanks to its compact footprint, the NH-L9x65 provides easy access to all connectors and components.
NF-A9x14 PWM premium fan

NF-A9x14 PWM premium fan

The highly optimised NF-A9x14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9x65 to stay remarkably quiet.
Low-Noise Adaptor

Low-Noise Adaptor

Allowing to reduce the maximum speed of the NF-A9x14 fan from 2500 to 1800rpm, the included (L.N.A.) makes it possible to achieve near-silent setups using CPUs with up to 65W TDP.
SecuFirm2™ mounting system for AM4

SecuFirm2™ mounting system for AM4

Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety and ease of use. In order to achieve the best compatibility and to match the airflow path inside the case, the SecuFirm2™ mounting for AM4 makes it possible to install the cooler either in standard orientation or turned by 90°.*
NT-H1 thermal compound

NT-H1 thermal compound

Having received more than 100 awards and recommendations from hardware journalists around the world, Noctua's NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability.
6-year manufacturer’s warranty

6-year manufacturer’s warranty

Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A9x14 features an MTTF rating of more than 150.000 hours and the entire NH-L9x65 package comes with a full 6-year manufacturer’s warranty.
*The possibility of installing the cooler turned by 90° depends on the free space around the CPU socket and can thus vary from motherboard to motherboard.

NH-L9x65 SE-AM4 Review

Noctua NH-L9x65 SE-AM4 is small but well performing cooler. It has all what you may need if you are looking for an AM4 cooler for your HTPC or even workstation. It performs well but also works quiet what isn’t expected on an eight core platform. There are of course better performing coolers like two other Noctua models which are in the comparison and we will tell you some more about them in next articles. However there are no other compact coolers for AM4 socket on the market which perform so good. What more so far there is no competition for Noctua NH-L9x65 and any other brand will have a hard time designing anything better.
Test verdict: "Noctua NH-L9x65 SE-AM4 is clearly the best choice if you are looking for a compact cooler for your AMD Ryzen computer. It’s small, well performing and quiet. What else you may need?" (Bartosz Waluk, FunkyKit.com)

NH-L9x65 SE-AM4

The following models can be made compatible with the AM4 socket free of charge using the NM-AM4 upgrade-kit:

NH-C12P
NH-C12P SE14
NH-C14
NH-C14S
NH-D14
NH-D14 SE2011
NH-D15
NH-D15S
NH-D9L
NH-L12
NH-L9x65
NH-U12
NH-U12F
NH-U12P
NH-U12P SE1366
NH-U12P SE2
NH-U9
NH-U9B
NH-U9B SE2
NH-U9F

The following models can be made compatible with the AM4 socket free of charge using the NM-AM4-UxS upgrade-kit:

NH-U14S
NH-U12S
NH-U9S

The following models can be made compatible with the AM4 socket using the NM-AM4 upgrade-kit but are not eligible for Noctua‘s free mounting offer, so users have to purchase the kit at local resellers:

NH-U12DO (Note that the A3 version is not compatible!)
NH-U12DX
NH-U12DX 1366
NH-U12DX i4
NH-U9DX i4
NH-U9DX 1366
NH-U9DO (Note that the A3 version is not compatible!)

The following models are not compatible with the AM4 socket and can not be upgraded:

NH-L9i
NH-U12DO A3
NH-U9 DO A3

We also aim to provide an upgrade-kit for NH-L9a, but due to some late changes to the AM4 platform, it is not yet clear whether installation will be possible. We are currently exploring the available options and will provide more information at a later date.

How can I determine if the motherboard’s UEFI BIOS is overclocking my processor by default and deactivate this automatic overclocking?

Most motherboard vendors allow their overclocking-enabled products (e.g. those with Intels X- or Z-series chipsets) to run the processor at increased clock speeds by default, without requiring any user action at all. Since TDP (Thermal Design Power) limits are usually also disabled by default, this leads to the CPU exceeding the rated TDP to a varying degree, depending on the used applications and their workloads. Due to the increased heat output of the CPU, you may see higher CPU temperatures than expected.

In order to find out if your motherboard is overclocking your processor by default, please enter the UEFI BIOS and select the “advanced” or “overclocking” menu. There you should be able to find options such as “MultiCore Enhancement” (options: enabled/disabled), “CPU Ratio Apply Mode” (options: all/per core) or similar. To disable the automatic overclocking, adjust the settings either to “disabled” or “per core” and make sure that the individual multipliers match the original specifications.

In doubt, please contact your motherboard vendor for detailed instructions on how to disable this feature.
