NH-D15 G2 chromax.black

All-Black Next-Gen Dual Tower Cooler

Reference-class quiet cooling performance all in black: The chromax.black version of the award-winning NH-D15 G2 flagship cooler.

Continuing the legacy of the iconic NH-D15, the NH-D15 G2 has quickly established itself as a new benchmark for premium quality quiet CPU coolers.

Utilising the same further refined 8-heatpipe heatsink and state-of-the-art NF-A14x25r G2 PWM fans, the chromax.black version offers the same winning combination of cutting-edge cooling efficiency and superb quietness of operation.

At the same time, its black fans and black coated heatsink enable it to merge these assets with a sleek stealth look.

Topped off with the Torx based SecuFirm2+ multi-socket mounting system, Noctua’s highest performing NT-H2 thermal compound and a full 6-year manufacturer’s warranty, the NH-D15 G2 chromax.black is a deluxe choice for everyone who seeks an elite-class heatsink that looks just as great as it cools.

• Second generation - Further improved second generation of the iconic NH-D15
• Superior performance - 8 heatpipes & 20% more surface area for higher heat-loads
• State-of-the-art fans - Dual NF-A14x25r G2 PWM fans with speed-offset

Award-Winning NH-D15 G2 Cooler

While the original NH-D15 has reigned supreme for an entire decade, the G2 model provides another step up in performance and technology. Further refined in virtually all respects from the heatsink and the fans all the way down to the mounting, thermal paste and accessory package, the NH-D15 G2 has become a new reference.

chromax.black Design

The NH-D15 G2 chromax.black is black from head to toe: Featuring a black heatsink with high thermal conductivity coating, 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.

Optimised, Asymmetrical Fin-Stacks

The NH-D15 G2 has been painstakingly optimised to best utilise the superior airflow and pressure performance of the novel NF-A14x25r G2 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.

Offset Design for Better PCIe Clearance

Like the NH-D15S, the NH-D15 G2 is offset towards the upper edge of the motherboard (when installed in standard orientation blowing towards the I/O panel) in order to increase clearance towards the PCIe slots. This enables it to clear the top PCIe x16 slot on most current motherboards (see motherboard compatibility list).

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 either be used with standard height RAM (up to 32mm) or, in chassis with more than 168mm CPU cooler clearance, the front fan can be moved upwards to make room for memory modules taller than 32mm.

Two NF-A14x25r G2 Fans

Noctua’s next-generation NF-A14x25r G2 fans set a new benchmark for performance-to-noise efficiency in round-frame 140mm fans. Their superb acoustics as well as their superior airflow and pressure characteristics are one of the cornerstones that enable the NH-D15 G2 to push beyond its legendary predecessor.

Speed-Offset for Optimal Acoustics

When two fans operate in a push-pull configuration running at the exact same speed, their acoustic interaction can lead to undesirable harmonics phenomena such as intermittent vibrations or periodic humming. Therefore, the two NF-A14x25r G2 PWM fans used on the NH-D15 G2 are slightly offset in speed (+/- ~25rpm) in order to ensure optimal acoustics.

PWM Control with Wide Speed Range

The NF-A14x25r G2 PWM fans can be PWM-controlled from their maximum speed of 1500rpm all the way down to 300rpm. This makes it possible to adjust them for maximum performance or near-silent operation using either automatic, temperature-based motherboard speed control or manual controllers such as the NA-FC1.

Fans Stop at 0% PWM

When the fans are set to 0% PWM duty cycle by the motherboard or PWM fan controller, they will stop. This makes the NH-D15 G2 ideal for creating setups with semi-passive cooling that automatically turn the fans off and thus run completely silent at idle if thermals allow.

Low-Noise Adaptors

The NH-D15 G2 is supplied with two Low-Noise Adaptors (L.N.A.) that reduce the maximum fan speed from 1500 to 1250rpm. The L.N.A.s can be used either to run the fans at a fixed speed of 1250rpm or to cap the maximum speed when using automatic PWM control.

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.
