Description
Product Overview
The Cable Matters 4‑Pin PWM Fan Splitter is a compact Y‑cable designed to connect two 4‑pin case fans to one motherboard fan header. Constructed from durable black plastic with a round 4‑pin connector, the splitter supports PWM control, allowing both fans to run at identical speeds based on motherboard software. Each fan can draw up to 12 watts at 12 volts, making it suitable for standard 80 mm to 140 mm cooling fans. The package includes two splitters, each 4 inches long, with male‑to‑female connectors for easy installation.
Usage
This splitter is perfect for desktop gamers, workstation builders, and PC enthusiasts who need additional airflow without sacrificing motherboard pins. Install the male connector into an available 4‑pin header on the motherboard, then attach two PWM‑compatible fans to the female ends. The synchronized RPM signal ensures consistent cooling performance, whether the system is under heavy load or idle.

FAQ
Can this splitter be used with 3‑pin fans?
Yes, the splitter works with both 3‑pin and 4‑pin fans, but PWM speed control is only available with 4‑pin fans.
Will the splitter affect fan performance?
No, the PWM signal is passed through unchanged, so both fans operate at the same speed as set in the BIOS or software.
Is the splitter compatible with all motherboards?
It fits any standard 4‑pin fan header found on modern ATX, micro‑ATX, and mini‑ITX motherboards.
How many watts can each fan draw?
Each fan can draw up to 12 watts at 12 volts, which is typical for most case fans.
Do I need additional software to use PWM?
Most motherboards include built-in PWM control in the BIOS or through bundled software; no extra drivers are required.
