92mm PWM Case Fan

The NF-B9 redux-1600 PWM is a 92mm square frame fan built for chassis ventilation and NAS cooling replacements. It connects via a standard 4-pin PWM header for automatic motherboard speed control. The rotor spins up to 1600 RPM while producing a maximum of 17.6 dB(A). Its rated MTTF exceeds 150,000 hours.

Suits compact cases and quiet builds

This 92x92x25mm unit fits mounts designed for the 92mm form factor and delivers a balance of static pressure and airflow at low noise. Builds requiring larger frame sizes for greater total airflow capacity cannot use this fan. Buyers needing pre-installed anti-vibration mounts or alternative voltage adapters must purchase those accessories separately.

1600 RPM maximum speed

The single specification that decides fit is the 1600 RPM ceiling under PWM control. It determines the peak airflow and static pressure available for cooling dense heatsinks or restricted chassis paths. Systems that demand higher rotational speeds for thermal headroom will need a different fan model.

Questions about this item

Will the 4-pin PWM connector on this 92mm fan work with a motherboard that only has 3-pin headers?

The 4-pin PWM plug fits a 3-pin header; the fan will run at full 1600 RPM without speed control.

How can I confirm the fan is running at the correct speed after installation?

Monitor the RPM reading in BIOS or fan-control software; it should scale up to 1600 RPM under load and drop near zero at idle.

Does the box include anti-vibration mounts or only the fan itself?

The redux package contains the fan only; anti-vibration mounts, S-ATA adaptors, y-splitters and extension cables are sold separately.
