Noctua 80mm PWM case fan

The Noctua NF-R8 redux-1800 PWM is an 80 by 80 by 25 millimetre case fan with a 4-pin PWM connector for automatic speed control. It uses an SSO bearing and runs at up to 1800 RPM. The streamlined redux edition delivers the proven NF-R8 design at an accessible price point.

Suits builds needing a single 80mm PWM fan

This unit suits builders who need one 80mm fan with motherboard-controlled speed regulation for chassis ventilation or NAS cooling. It is not for systems requiring multiple fans in the box, nor for setups that demand a bundled fan controller or voltage adapter.

1800 RPM maximum speed

The 1800 RPM top speed defines the airflow and acoustic ceiling of this model. Buyers who need higher static pressure or lower minimum noise at idle should look at alternative specifications.

Questions about this item

Will the 80x80x25 mm frame and 4-pin PWM connector fit the same mounting holes and headers as my existing 80 mm fans?

Yes, the fan uses the standard 80x80x25 mm footprint and a 4-pin PWM connector, so it matches the screw pattern and motherboard header of other 80 mm fans you may already have.

How can I confirm the fan is running at the intended 1800 RPM and 17.1 dB(A) after installation?

Monitor the RPM reading in your BIOS or fan-control software; it should report up to 1800 RPM under load, and the acoustic level at that speed is rated at 17.1 dB(A).

Does the box include only the fan and four screws, or are anti-vibration mounts and adapters also supplied?

The package contains the fan and four mounting screws; anti-vibration mounts, S-ATA adapters, y-splitters and extension cables are sold separately.
