The ARCTIC 4-Pin PWM Fan Splitter Cable lets PC builders connect up to four case fans to a single motherboard fan header. It suits a system with several case fans and limited fan headers, and helps keep their wiring routed neatly through the case.

A single PWM signal is shared across the connected fans for synchronous speed control. The cable is 700 mm long overall, with 400 mm to the first socket and 100 mm between sockets. Its flexible, slim cables can be routed through narrow spaces and tucked into existing cable management. The system reads the RPM signal from the first fan socket.

Key features

• Connects up to four fans to one 4-pin PWM header.
• Sends the configured PWM signal to all connected fans.
• Reports the RPM reading from the first socket.
• Supports 3-pin fans and connectors with voltage-based speed control.
• Provides 400 mm of cable to the first fan socket.
• Has 100 mm between fan sockets to help position fans around a case.

Compatibility

Connect the cable to a 4-pin PWM fan header and attach up to four compatible case fans. 3-pin fans and connectors are also supported, with speed controlled via voltage. Good to know: only the first socket returns an RPM signal; if the total fan power consumption exceeds 1 A, ARCTIC recommends using its SATA-powered Case Fan Hub.

Specifications

For a build that needs more fan connections from one motherboard header, this splitter adds four outlets and keeps the wiring flexible around the case.
