Three direct contact copper heat pipes effectively transfer heat for optimal dissipation through the heat sink tower. The 92mm PWM fan outputs balanced airflow for performance and silence.

New Family Appearance

The AG300 adopts a new DeepCool family design and features a unique matrix fin array that densely packs each fin for a neat and firm construction. The nickel plated heat pipes provide extra protection against copper corrosion.

Easy Installation

Compatible with multiple socket platforms from Intel and AMD with support for the latest changes. Ensure a proper mount pressure with the included brackets for a seamless installation.

Standing 158mm tall, the NH-U12S is short enough to fit most modern mid- or high-end tower cases. Measuring 125mm wide (including fan and fan clips), the cooler stays clear of the top PCIe slot on most standard ATX or Micro-ATX motherboards, ensuring optimum compatibility with multi-GPU setups.

PWM support and Low-Noise Adaptor

The NF-F12 120mm fan supplied with the NH-U12S supports PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 1500 to 1200rpm using the supplied Low-Noise Adaptor for even quieter operation.

Anti-vibration pads and fan-clips for second NF-F12 

For users who want to achieve even better performance by adding a second, optional NF-F12 fan to create a push/pull setup, the NH-U12S includes fan clips and an extra set of custom-designed anti-vibration pads that allow to off-set the rear fan by 5mm to improve acoustics in dual-fan mode.

Compatibility with past and future sockets

Complying with the open SecuFirm standard, the NH-U12S 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.

Standing 158mm tall, the NH-U12A is short enough to fit most modern mid- or high-end tower cases. Measuring 125mm wide (including fan and fan clips), the cooler stays clear of the top PCIe slot on most standard ATX or Micro-ATX motherboards, ensuring optimum compatibility with multi-GPU setups.

Dual NF-A12 120mm fans

The NF-A12x25 is a highly optimised next-generation 120mm fan that integrates Noctua’s latest innovations in aerodynamic engineering in order to achieve an unprecedented level of quiet cooling performance. Using this elite-class fan in a push/pull dual fan configuration is one of the cornerstones of the NH-U12A’s commanding performance and acoustic efficiency.

SecuFirm2 multi-socket mounting system

Noctua’s SecuFirm2 mounting systems have become synonymous with quality, safety and easy installation. Supporting Intel LGA1851, LGA1700 (since 2021), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) as well as AMD AM4 and AM5 (since 2019), the SecuFirm2 mounting included with the NH-U12A is straightforward to install, provides perfect contact pressure and will stand the test of time even under heavy use.

Soldered interface between heatpipes and fins

With many heatsinks, the fins are press-fitted to the heatpipes. Due to the different thermal expansion coefficients of copper and aluminium, this fit can loosen over years of thermal cycling, which may lead to reduced performance. By contrast, the NH-U12A’s fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesn’t deteriorate even after many years of usage.

Thanks to its recessed lower fins, the NH-D15S provides 66mm clearance for RAM with tall heatspreaders or RGB illumination, making it compatible with most high-end modules on the market. As the lower fins are recessed on both sides of the heatsink, compatibility is excellent on both Intel and AMD sockets.

Asymmetrical layout for better PCIe compatibility

As many current motherboards have the top PCIe x16 slot sitting close to the socket, bigger heatsinks tend to block it. Due to its asymmetrical layout, the fin-stack of the NH-D15S is off-set towards the upper edge of the motherboard when installed in standard orientation. This allows it to clear the top PCIe x16 slot on most current µATX and ATX motherboards.

Dual-fan ready

Using the supplied extra fan clips, the NH-D15S can be upgraded with either a second round-frame 140mm fan with 120mm mounting holes (such as the NF-A15) for maximum performance or a common 120mm fan (such as the NF-F12) for improving performance while maintaining compatibility with RAM modules of up to 45mm height.

PWM support and Low-Noise Adaptor

The NF-A15 premium fan supplied with the NH-D15S supports PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 1500 to 1200rpm using the supplied Low-Noise Adaptor for even quieter operation.

PWM support and Low-Noise Adaptors

The NF-A12 120mm fans supplied with the NH-U12A support PWM for convenient automatic speed control through the motherboard: full performance under load, virtually silent at idle! In addition, maximum fan speed can be reduced from 2000 to 1700rpm using the supplied Low-Noise Adaptors for even quieter operation.

Compatibility with past and future sockets

Thanks to Noctua’s SecuFirm ecosystem, the NH-U12A can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets, which makes the NH-U12A a safe long-term investment.

NT-H1 thermal compound

Noctua’s much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability. Chosen again and again by overclockers and enthusiast users worldwide, it has established itself as a benchmark for premium-quality thermal compounds.

The NH-D15 G2 has been painstakingly optimised to best utilise the superior airflow and pressure performance of the novel NF-A14x25r G2 PWM fans. Thanks to the fans’ improved P/Q performance, the fin-spacing could be reduced from 1.9mm to 1.6mm, which made it possible to integrate 26 extra fins and increase total fin surface area by 20%. At the same time, the width of the front fin-stack has been cut by 5mm so that the loading is more balanced between the two fans.

More performance, smaller size

Thanks to the higher fin density made possible by the new NF-A14x25r G2 fans as well as the asymmetrical fin-stacks and a slightly smaller gap between the stacks, the G2 version combines improved performance with a slightly smaller size compared to the original NH-D15 (9mm less heatsink depth, same heatsink width, same total height including fans).

8 heatpipes for superior performance at higher heat-loads

The NH-D15 G2 utilises eight instead of six heatpipes compared to the original NH-D15. The increased thermal capacity of the extra heatpipes is especially helpful at extreme heat-loads such as 250W and beyond, where the performance boost over the original NH-D15 is the biggest.

Regular all-round version with medium base convexity

The regular NH-D15 G2 uses the same medium base convexity as most other Noctua heatsinks, which makes it a perfect all-rounder that provides optimal results on AM5 with the included offset mounting and on fresh, unused LGA1700 CPUs when utilising the included NM-ISW1 shim washers or so-called contact frames to reduce CPU deformation from ILM pressure.

High RAM compatibility in single fan mode

Thanks to its recessed lower fins, the NH-D15 G2 provides at least 59mm clearance for tall memory heatsinks in single fan mode, making it compatible with most high-end RAM modules on the market. In dual fan mode, the NH-D15 G2 should be used with standard height RAM (up to 32mm, please refer to RAM compatibility list)

Excellent component cooling

Extending below the fin-stacks, the large NF-A14x25r G2 fans not only contribute to the NH-D15 G2’s superb CPU cooling capabilities, but also provide massive airflow over surrounding motherboard heatsinks and components such as VRMs, thus ensuring excellent component cooling performance.

The NH-D15 chromax.black is black from head to toe: Featuring a black coated heatsink, black fans with black anti-vibration-pads, black fan clips and black mounting parts, it’s right at home in all-black builds and easy to integrate with other colour schemes.

6 heatpipe dual tower design

As compared to conventional single tower heatinks, the NH-D15’s fine-tuned six heatpipe dual tower design provides more surface area, better heat-distribution and superior airflow efficiency in dual fan mode.

Widened fin stack and expanded heatpipe layout

Compared to the NH-D14, the NH-D15’s fin-stack has been widened from 140 to 150mm and its heatpipes are now spaced further apart, which allows for a more uniform heat distribution over a larger surface area and thus contributes to the NH-D15’s superior efficiency.

PWM support and Low-Noise Adaptors

The NF-A15 premium fans supplied with the NH-D15 support PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 1500 to 1200rpm using the supplied Low-Noise Adaptors for even quieter operation.

Offset mounting option for AMD AM5

The NH-D15 chromax.black includes Noctua’s offset mounting bars for AM5 that make it possible to install the cooler shifted towards the south side of the socket by 7mm, thereby achieving better contact quality right above the CCD(s). This improved contact exactly at the processor’s hotspot can significantly reduce CPU temperatures with typical improvements in the range of 1-3°C.

NT-H1 thermal compound

Noctua’s much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability. Chosen again and again by overclockers and enthusiast users worldwide, it has established itself as a benchmark for premium-quality thermal compounds.

Compared to the award-winning NH-D15, the S-version uses an off-set, asymmetrical layout and a single instead of dual NF-A15 fans. This allows the NH-D15S to provide state-of-the-art heatsink performance while maintaining superior RAM and PCIe compatibility.

Asymmetrical layout for better PCIe compatibility

As many current motherboards have the top PCIe x16 slot sitting close to the socket, bigger heatsinks tend to block it.

This allows it to clear the top PCIe x16 slot on most current µATX and ATX motherboards.

NF-A15 140mm fan

Complying with Noctua’s AAO standard and featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A15 has quickly built up a reputation as one of the best 140mm fans on the market.

Dual-fan ready

Using the supplied extra fan clips, the NH-D15S can be upgraded with either a second round-frame 140mm fan with 120mm mounting holes (such as the NF-A15) for maximum performance or a common 120mm fan (such as the NF-F12) for improving performance while maintaining compatibility with RAM modules of up to 45mm height.
