Enlarging its portfolio of premium quality quiet fans, Noctua today announced PWM versions of its renowned NF-P12, NF-B9 and NF-R8 fans.

PRESS RELEASE

Having received more than hundred awards and recommendations from the international press, the classic NF-P12, NF-B9 and NF-R8 fans helped to found Noctua's reputation as a top-tier manufacturer of premium grade quiet cooling components. The new PWM versions build on the proven designs and feature Noctua's novel NE-FD1 IC for fully automatic control and ultra-low power consumption.

"Our customers have been asking us for PWM versions of our fans for a long time, but the available PWM fan driver ICs simply weren't up to our quality standards", explains Mag. Roland Mossig, Noctua CEO. "With our NE-FD1, we've
now got our custom-designed IC that allows us to build PWM fans that consume less power and remain quieter at low speeds."




Most conventional PWM fan driver ICs put out square signals that cause sudden torque impulses. These impulses can cause minute deformations of the entire fan structure which lead to audible "clicking" noises that are
especially noticeable with many common PWM fans running at slower speeds. Adopting Noctua's Smooth Commutation Drive (SCD) technology, the custom designed NE-FD1 PWM IC slows down the slew rate of the output signal in
order to give a smoother, less sudden torque impulse. This way, PWM switching noises can be effectively suppressed and the fan runs even quieter, especially at low speeds.

Noctua's NE-FD1 IC was not only fine-tuned for superior quietness, it has also been carefully optimised to allow for ultra-low power consumption. As a result, the new PWM models consume 25-40% less power than their non-PWM
counterparts.

All models come with Low-Noise Adaptors, 30cm cable extensions and 4-pin y-cables that allow to connect a second PWM fan to the same fan header for automatic control. Equipped with Noctua's signature SSO bearing and topped
off with a 6 years manufacturer's warranty, the NF-P12 PWM, NF-B9 PWM and NF-R8 PWM are a proven premium choice for the highest demands.

Price and Availability
The new PWM models are available immediately at a recommended retail price of EUR 19.90 / USD 24.90 (NF-P12 PWM), EUR 17.90 / USD 21.90 (NF-B9 PWM) and EUR 14.90 / USD 18.90 (NF-R8 PWM).
