Compact 92mm case fan for quiet airflow

The Noctua NF-B9 redux-1600 is a single 92x92x25 mm case fan built for quiet chassis ventilation. It spins at 1600 RPM and moves 64,3 m³/h of air while producing 17,6 dB(A) of noise. The SSO bearing and Vortex-Control Notches keep operation smooth and the sound signature pleasant. It connects via a standard 3-pin power connector.

Ideal for tight spaces and NAS upgrades

This fan suits builders who need a slim 92mm cooler for small-form-factor cases or a drop-in replacement for NAS enclosures and other space-constrained devices. The redux packaging omits accessories such as anti-vibration mounts and adaptors, so buyers who want those extras should look at a full retail kit. Users who require PWM speed control will need a 4-pin model instead.

3-pin voltage control at 1600 RPM

Speed is managed by varying the 12 V supply voltage on the 3-pin connector, and optional low-noise adaptors can reduce the maximum RPM further. This single specification determines whether the fan integrates with your motherboard or fan controller.

商品問答

What does the 3-pin connector limit for speed control?

The 3-pin connector allows voltage-based speed control but lacks a dedicated PWM wire for automatic motherboard regulation.

What clearance does the 25 mm thickness and 92 mm frame require?

It fits standard 92 mm mounting holes with 25 mm depth, so verify your chassis or NAS bay has at least 25 mm of free space behind the screw plane.

How do the four supplied screws install, and what mistake is common?

Drive the screws straight through the fan's corner holes into the case threads; the frequent error is cross-threading or over-tightening, which can strip the soft plastic frame.
