Noctua 92mm Fan NF-B9-redux-1600-PWM

This is a 92 mm fan Noctua NF-B9-redux-1600-PWM – a compact case fan for stable and quiet cooling, especially suitable for smaller cases and dense configurations. It operates in the range of 350 to 1600 RPM, giving you a good balance between airflow and low noise. At maximum speed, it pushes up to 37.85 CFM of air with a noise level of only 17.6 dBA, which is quite quiet for this size. This is the typical “set & forget” fan – you install it, set the PWM curve, and forget about it for years.

What you get

With a size of 92 x 92 x 25 mm, the fan is ideal for front or rear positions in more compact cases where 120 mm simply won't fit. The PWM connector with 4 Pin allows you to connect it directly to the motherboard and control the speed according to the temperature – running at ~350 RPM almost silently when idle, and ramping up to 1600 RPM under load for more serious airflow. The SSO Bearing is designed for long life and stable operation, which combined with MTBF 150000 hours and 72 months warranty makes it a very long-term solution. The low consumption – only 0.96 W at 12 V and 0.08 A – hardly burdens the fan headers on the motherboard and is completely safe for standard connectors.

• Compact size of 92 mm, suitable for small cases, tight spaces, and specific airflow positions.
• Speed range of 350–1600 RPM, giving you flexible control from completely silent mode to stable cooling under load.
• Airflow up to 37.85 CFM / 64.3 m3/h, sufficient for effectively exhausting warm air from the case or bringing in fresh air from outside.
• Low noise level of only 17.6 dBA, making it suitable for quiet gaming and workstations, as well as for systems in bedrooms or offices.
• SSO Bearing and MTBF 150000 hours, aimed at long and reliable operation without rattling and vibrations over time.
• 4 Pin PWM connector for automatic speed control through the motherboard, without the need for additional controllers.
• Low consumption of 0.96 W at 12 V / 0.08 A, gentle on the fan headers and suitable for more modest systems.
• Clean gray color without RGB lighting, suitable for a simple, unobtrusive build.
• Long 72 months warranty, supporting the idea of a fan that you install and forget.

Who it is suitable for

This fan is suitable if you are building a compact machine, HTPC, or office/quiet system and need a reliable 92 mm fan for intake or exhaust. If your case only supports this size or you are aiming for maximum silence with PWM control, this will fit perfectly. It is not RGB-oriented, so if you are looking for a “show” with lighting, this will not be your fan.

The combination of quiet operation at 17.6 dBA, PWM control in the range of 350–1600 RPM, and long life with SSO bearing and 150000 hours MTBF makes it a very sensible choice for reliable and unobtrusive cooling.
