PWM Fan Splitter Cable 1-To-4 Black Mesh Sleeved – 4-Pin Female To 4x 4-Pin Male Connectors – 10 Inch Extension – Supports RPM Signal On One Fan – Compatible With 3-Pin & 4-Pin Fans

⚙️ Features

• 1-to-4 Fan Expansion – Connects up to four case or CPU fans from a single 4-pin motherboard header (CPU_FAN or SYS_FAN).
• PWM Signal Synchronization – All connected fans follow the same PWM signal, allowing unified speed control via motherboard software (AI Suite, EasyTune, Fan Xpert, etc.).
• Accurate RPM Monitoring – Only one fan connector (full 4-pin) sends RPM feedback to the motherboard to avoid signal conflicts.
• Universal Compatibility – Works with both 4-pin PWM fans and 3-pin DC fans (3-pin fans will run at full speed).
• Premium Sleeved Design – Black sleeved braiding for better durability, aesthetics, and easier cable management.
• Stable 12V DC Power – Ensures consistent voltage delivery to all connected fans.

🔌 Connector Layout

⚠️ Note: Connect the 4-pin male with all pins to the fan you wish to use for RPM monitoring. The others are missing the tachometric (RPM) pin by design.

🧠 Smart Design

• Prevents RPM signal interference that can cause unstable readings.

• Ideal for PWM-capable motherboard headers (check your board’s specs to confirm PWM support).

• Works great for compact builds where limited headers are a constraint.
