The Silverstone 1-to-8 PWM Fan Hub is capable of expanding one motherboard PWM fan header to support up to 8 fans. Powered directly by a SATA cable from the power supply and filtered through a built-in 2200μF capacitor, the CPF04 can provide clean, stable voltage to any fan for optimal performance. Equipped with speed detection sensors for accurately controlling 8 PWM fans simultaneously, the Silverstone fan hub is an excellent solution for system fan expansion.
