80mm Case Fan for Compact Builds

The Noctua NF-R8-1800 is an 80mm case fan built for systems where space is limited. It uses a self-stabilising oil-pressure bearing for quiet operation and long service life. The rotor design was developed with an Austrian research institute to optimise blade geometry for low noise. This single fan suits small-form-factor PCs and tight mounting points.

Suited for Low-Noise 80mm Mounts

Buyers who need an 80mm fan with three preset speed options will find this model practical. The package includes low-noise and ultra-low-noise adapters to reduce speed from the default 1800 RPM. Builders who require PWM control or addressable lighting should look elsewhere. The fan has no integrated controller or LEDs of any kind.

1800 RPM Maximum Speed with Adapters

The fan runs at 1800 RPM at full voltage and produces 17 dB(A) of acoustical noise. With the supplied low-noise adapter the speed drops to 1300 RPM and noise to 10 dB(A). The ultra-low-noise adapter further reduces speed to 800 RPM and noise to 7 dB(A). These three fixed operating points determine whether the airflow meets the thermal needs of the build.

Questions about this item

How often will the SSO bearing need maintenance?

The self-stabilising oil-pressure bearing is self-lubricating and designed for long-term stability without user maintenance.

What limits continuous operation at 1800 RPM?

The fan runs at 1800 RPM with a 17 dB(A) noise level; sustained use stays within this acoustic rating.

How loud and hot does it get running all day at full speed?

At 1800 RPM it produces 17 dB(A); with the supplied Low-Noise Adaptor it drops to 1300 RPM and 10 dB(A), and with the Ultra-Low-Noise Adaptor to 800 RPM and 7 dB(A).
