Description

⚙️ 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. 📐 Specifications Specification Details Cable Type PWM 1-to-4 Fan Splitter Connector A 4-pin Female (Motherboard side) Connector B 1x 4-pin Male (with tach signal) Connector C 3x 4-pin Male (no tach pin) Compatibility 3-pin and 4-pin fans Power 12V DC Length 10 inches (approx. 26.9 cm) Color Black Sleeved Use Case CPU cooler, case fans, fan hubs 🧠 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.
