1 to 5 4Pin PWM Fan Hub Extension Cable, 4Pin PWM CPU Case Cooling Fan Power Splitter Adapter Cable for PC Chassis, Motherboard PWM Port MultiFan Synchronous Speed Control

This 1 to 5 4Pin PWM fan hub extension cable is a practical PC cooling accessory designed to expand a single motherboard 4pin PWM fan header into five fan connections. It allows you to run multiple CPU fans and case cooling fans simultaneously while retaining PWM speedcontrol functionality, so all connected fans can adjust rotation speed synchronously responding to motherboard temperature feedback.

Constructed with highquality purecopper wire cores, this splitter delivers stable power output and consistent PWM signal transmission, preventing abnormal fan speed fluctuation or connection failure. Flexible outer cable jacket resists bending damage and helps tidy internal chassis cable routing. Precisionmolded 4pin connectors offer tight insertion force to avoid loose contact caused by case vibration.

Simply plug the main 4pin male connector into your motherboard PWM fan header, then attach your 4pin PWM cooling fans to each of the five output ports. No software or driver installation required. Important note: please check total power consumption of all connected fans to avoid overloading your motherboard fan header. It is perfectly suited for gaming PC assembly, watercooling setups and highairflow chassis modification projects. This splitter works for both 4pin PWM fans; 3pin fans can run but will lose PWM speedadjust function.
