Noctua NF-R8 PWM Processor Fan

Proven NF-R8 Design
Tens of thousands of quiet cooling enthusiasts swear by Noctua’s classic NF-R8. Its impressive quietness, excellent performance and impeccable, time-tested quality made the R8 a default choice for 80mm quiet cooling.

Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-R8 PWM uses Noctua’s novel, custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at lower speeds.

Low-Noise Adaptor
The NF-R8 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 1800 to 1300rpm. The L.N.A can be used either to run the fan at a fixed speed of 1300rpm or to cap the maximum speed when using automatic PWM control.

Extensive Cabling Options
The fan’s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows to connect a second NF-R8 fan to the same PWM fan header for automatic control.
