Air cooler Noctua NH-D15 G2 — dual-fan 140 mm CPU cooler, copper, 12 V, 1500 RPM max, compatible with LGA 1150/1151/1155/1156/1200/1700 and AM4/AM5

The Noctua NH-D15 G2 is a second-generation premium air cooler designed for high-end desktop processors. It combines two NF-A14x25r G2 PWM 140 mm fans, eight heatpipes and asymmetrical fin-stacks to deliver improved quiet cooling compared to its predecessor while offering enhanced compatibility and mounting features. The cooler includes Noctua’s SecuFirm2+™ Torx-based multi-socket mounting system, NT-H2 thermal compound, NM-ISW1 shim washers for LGA1700, and Low-Noise Adaptors, and comes with a 6-year manufacturer’s warranty.

Advantages

The NH-D15 G2 offers next-generation air-cooling performance with lower temperatures under high heat loads, increased fin surface area and higher fin density enabled by the NF-A14x25r G2 fans, and eight heatpipes for greater thermal capacity. Its asymmetrical, offset design improves PCIe clearance and RAM compatibility in single-fan mode. Included accessories such as NT-H2 thermal paste, NM-ISW1 shim washers, Low-Noise Adaptors and a Torx screwdriver simplify installation and platform-specific optimisation. The fins are soldered to the heatpipes to ensure long-term thermal reliability.

Suitable for (tasks / use cases)

• Cooling high-performance desktop CPUs in air-cooled systems

How to use

Install the SecuFirm2+™ mounting system following the included instructions and use the supplied Torx screwdriver for secure fastening. For AM5 installations, consider using the included offset mounting bars to shift the cooler for improved contact above CCDs. On LGA1700, use the NM-ISW1 1 mm shim washers when recommended to reduce ILM pressure and improve contact with low or medium convexity bases. Connect the fan headers to motherboard PWM headers for automatic speed control or use a manual controller; fans will stop at 0% PWM if the motherboard or controller sets that duty cycle.

Recommendations

Choose the NH-D15 G2 variant that matches your CPU’s heatspreader shape: regular (medium base convexity) for general use, LBC for flat heatspreaders and AM5 without offset, or HBC for CPUs with concave/deformed heatspreaders or heavy ILM pressure. Use Low-Noise Adaptors to cap maximum fan speed or NT-H2 thermal compound for optimal thermal transfer.
