4Pin PWM Fan Hub with SATA Power Supply Adapter, MultiFan Extension Splitter Cable, Supports Up to 10 Fans Synchronous Speed Control for PC Case Cooling System

This PWM fan hub is a multifan expansion splitter for desktop PC case cooling systems. It expands one motherboard 4pin PWM fan header to support up to 10 cooling fans, solving the problem of insufficient fan ports on the mainboard when building highperformance cooling setups.

It adopts SATA power supply as the main power source for all connected fans, which avoids overloading the limited current output of motherboard fan headers. The PWM speedcontrol signal is still obtained from the motherboard fan header, so all connected fans can adjust rotation speed synchronously according to system temperature.

Each port supports both 4pin PWM fans and ordinary 3pin DC fans. Flexible cable makes routing easier inside computer cases, helping organize messy internal wires. Ideal for gaming PC builds, watercooled systems, workstation computers and case modification projects.

Please note that total power consumption of all connected fans cannot exceed the rated load of the SATA power output. It is a practical cooling accessory for DIY PC builders and hardware enthusiasts.
