Case Fan Noctua NF-A15 HS-PWM chromax.black (fan only, from cooler) 140mm Color:black

Case Fan Noctua NF-A15 HS-PWM chromax.black (fan only, from cooler)

The Noctua NF-A15 HS-PWM chromax.black is an all-black 140 mm fan, the same fan Noctua supplies with the NH-D15 chromax.black CPU cooler. Its round frame is 150 mm wide and 140 mm tall, designed for large heatsinks, and the 105 mm mounting hole spacing also fits 120 mm fan mounts.

This item is sold as a fan only, taken from a Noctua CPU cooler kit, without original packaging, L.N.A. adaptor, pads or screws. It suits replacing a fan on a Noctua cooler, adding a second fan to a dual-tower heatsink, or use as a quiet premium case fan.

The fan reaches up to 1500 RPM with 140.2 m³/h airflow at only 24.6 dB(A). Flow Acceleration Channels, the AAO frame, the SSO2 bearing and a PWM IC with SCD keep it quiet even at low speeds, and it stops completely at 0% PWM.

Key features

• 140 mm fan, 150 mm wide frame - A 150 mm width that matches most large heatsinks and a 140 mm height that does not protrude above them. 105 mm hole spacing also allows installation in place of a 120 mm fan.
• Flow Acceleration Channels - Channels on the suction side of the blades speed up the air at the outer blade regions, reducing flow separation and improving efficiency and quietness.
• AAO frame - Advanced Acoustic Optimisation frame with integrated anti-vibration pads, Stepped Inlet Design and Inner Surface Microstructures for lower noise.
• SSO2 bearing, brass shell - Second-generation SSO bearing with the magnet closer to the axis and a CNC-milled brass bearing shell, for an MTTF of more than 150,000 hours.
• Quiet PWM, stops at 0% - The NE-FD1 IC with Smooth Commutation Drive suppresses switching noise at low speeds, and the fan stops completely when the board sets 0% PWM.
• chromax.black - An all-black look for black-themed builds, exactly like the fans in Noctua chromax.black cooler kits.
