Koeler Noctua NH-D15 14 cm beige bruin staal 1500 tpm 140,2 m³/u

The Noctua NH-D15 is an elite-class dual-tower CPU cooler based on the award-winning NH-D14. It combines a widened fin stack, an expanded six-heatpipe layout and two premium NF-A15 140mm PWM fans to deliver high-efficiency, low-noise cooling suitable for demanding desktop and workstation systems. The cooler includes Noctua's SecuFirm2™ multi-socket mounting system, NT-H1 thermal compound and a 6-year manufacturer warranty.

Advantages

The NH-D15 offers improved surface area and heat distribution over single-tower designs thanks to its six-heatpipe dual-tower architecture and a widened 150mm fin stack. Two NF-A15 140mm fans with PWM support and Low-Noise Adaptors enable automatic speed control and quieter operation when required. The recessed lower fins provide good RAM clearance in single-fan mode, and the large fans also enhance cooling for nearby motherboard components.

Suitable for

• High-performance desktop CPUs and workstations
• Overclocking and thermal-demanding tasks
• Silent-focused builds where low noise is important
• Systems requiring robust component cooling around the CPU socket

How to use

Install the SecuFirm2™ mounting system according to the included instructions for your CPU socket, apply a thin, even layer of the supplied NT-H1 thermal compound to the CPU heatspreader, and mount the heatsink ensuring secure contact pressure. Connect the fans to the motherboard CPU fan headers to allow PWM control. For RAM clearance, use a single fan configuration if taller memory modules are installed; in cases with more than 165mm cooler clearance in the chassis, the front fan can be moved upwards to accommodate taller modules.

Recommendations

Use the supplied Low-Noise Adaptors to reduce maximum fan speed for quieter operation when full cooling capacity is not required. For best results, ensure good case airflow and verify socket compatibility before installation; optional mounting kits are available from Noctua for legacy sockets.
