Noctua is known for its quiet fans and today announced new PWM versions of its NF-P12, NF-B9 and NF-R8 fans. Each of the PWM version fans come equipped with Noctua's NE-FD1 IC controller for better control over fan operation, especially at lower speeds. According to Noctua, most conventional PWM fan driver ICs put out square signals that cause sudden torque impulses resulting in fan clicking noises due to deformations in the fan body. These clicking noises become especially noticeable at lower fan speeds. With Noctua's NE-FD1 IC fan controller reduces the sudden torque impulse, effectively suppressing fan switching noises. Additionally, the new PWM models consume 25-40% less power than their non-PWM counterparts. Each fan also comes with 30cm cable extensions and 4-pin Y-cables allowing you to connect a second PWM fan to a single fan header. 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) and come with a six-year warranty.
