Fan PWM
Temperature control extension cable
Supports PWM speed control
Can expand multiple fans, only occupying one motherboard FAN interface
1. Ground
2. +12V power supply
3. Fan speed signal
4. Fan speed control
In order for the motherboard PWM chip to correctly recognize the fan speed signal, the extension cable is designed to only read the speed signal of the first expansion fan

One-To | SATA to Small 4-Pin Connector, 2 Pins 2 Wires

The reason why the third pin of the other interfaces on the extension cable, except for the first interface, is left empty
The PWM speed control interface is the fourth pin, and all temperature-controlled fans connected to the extension cable adjust their speed based on the PWM pulse signal of this pin
Solves the problem of insufficient motherboard ports with a 4-pin temperature-controlled PWM adapter cable, available in multiple specifications
Fully utilizes the limited number of motherboard 4-pin interfaces, allowing for the expansion and connection of multiple 4-pin/3-pin fans
To avoid signal conflicts when measuring speed simultaneously, some interfaces are split out
