Silverstone CPF04 1-to-8 PWM Fan Hub (SST-CPF04)

The Silverstone CPF04 1-to-8 PWM Fan Hub [SST-CPF04] is an essential expansion module for enthusiasts building high-airflow systems that exceed standard motherboard header limits. By consolidating up to eight fans into a single control source, it simplifies cable management and ensures uniform cooling performance across your entire chassis.

This hub features a high-capacity 2200μF capacitor, which serves to filter power and provide a stable, clean voltage to all connected fans, preventing RPM fluctuations. By drawing power directly from the PSU via a SATA connector, it protects your motherboard’s delicate circuitry from the high current draw associated with multiple high-performance or industrial-grade fans.

Key Features & Specifications

• Massive Expansion: Converts a single motherboard PWM header into eight 4-pin fan ports, allowing for extensive cooling arrays.

• SATA Powered: Operates independently of motherboard power limits, supporting a total output of up to 4.5A (54W).

• Voltage Stabilization: The integrated 2200μF capacitor smooths out power spikes to maintain consistent fan speeds and reduce electrical noise.

• Precision Speed Detection: Includes a designated glossy-side header that supports RPM speed detection, allowing the motherboard to accurately monitor and control the fan curve.

• Flexible Installation: Includes a 500mm PWM signal cable and a 300mm SATA power cable, providing ample length for routing behind motherboard trays.
