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.
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.
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 that 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.
Combining the proven concept of hydrodynamic bearing w/ an add'l magnet tht supports the self-stabilisation of the rotor axis， Noctua’s time-tested SSO-Bearing tech. has become synonymous w/ supremely quiet operation & exceptional long-term stability.
