Parameters of Giryriz PWM Fan Splitter Cable (Hub): Cable Length: 43CM/16.9IN Fan Plug: 2510-2Pin (For PWM speed regulation) Power Supply Plug: SATA/Molex Rated Voltage: 12V Rated Temperature (Max): 80℃ Insulation Material: PVC + Woven net About Cable: 24AWG wire, high quality tinned copper material. Product Function: Converts 4-Pin to one 4-Pin and four 3-Pin. Important Attention: 1) There are two plugs on the male end of this fan power extension cable, one is the power supply interface (SATA/Molex), which is plugged into the power supply, and the other is the 2-Pin speed measurement and temperature control (PWM) function, it must be plugged into 4-PIN CPU FAN socket of the computer motherboard, so that all the fans can realize the synchronous temperature control function with the motherboard at the same time. 2) The motherboard can only provide the accurate speed measurement value of one fan, so only one of the fans (4-Pin Socket) has speed measurement function, but all the fans have PWM temperature control function.

This PC fan power extension cable allow you to add additional case fans to increase airflow in your desktop computer case, improve your computer’s performance. This fan splitter cable adopt 24AWG wire, high quality tinned copper material (No recycled materials), good conductivity, reliable and durable, rated temperature: 80℃. Converts one 4-Pin to 4 of 3-Pin/4-Pin. This PWM fan splitter cable with a 4-Pin male connector at one end and splits to 4 female connectors at the other end. Cable length (Approx): 43CM/16.9IN. Giryriz PWM fan splitter cable is compatible with all 4-Pin and 3-Pin case fans. The 2nd generation uses SATA interface to provide sufficient power for the fans and ensure the PWM speed regulation function. It can reduce the load of PC motherboard and improve its service life. [IMPORTANT ATTENTIONS] - The fan plug (Male) must be plugged into “4-Pin CPU fan socket” and set fan mode as smart mode in BIOS. If it is plugged into the 3-Pin or other 4-Pin fan socket (Not CPU fan socket), it will be unable to use the speed regulation function (This has nothing to do with the product itself), and the fan can only operate at the rated speed.
