⚙️ 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

Connector Type Purpose
1x 4-pin Female Plugs into motherboard header
1x 4-pin Male (Full) Sends RPM signal back to motherboard
3x 4-pin Male (No Tach) For fan power + PWM only (no RPM feedback)

⚠️ 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.
