PWM Fan Hub Desktop Computer CPU Fan Expander Supports 3Pin&4Pin

1. 10-port fan expansion
2. Fully gold-plated PCB circuit board, hyphens are all gold
3. The layout is more user-friendly, and the internal space of the chassis is optimized. The power cord and the CPU PWM fan control line are on the same side, and only need to plug in three directions, which saves the area and space of the host
4. Equipped with 10 capacitors to provide more stable and safe power to your fan
5. Equipped with a standard SATA15PIN power supply interface, the gold finger of the power supply interface is hidden downwards, and the double harpoon positioning welding feet make the socket more stable and reliable
6. Equipped with a strong double-sided adhesive EVA cotton with a thickness of 2mm. EVA completely covers the bottom, protects the bottom solder joints, and avoids short circuit caused by contact with the metal chassis. It can also be fixed on any position of the host by EVA paste, which can be on the bottom or top , you only need to paste it on the back and wherever you want to put it
7. Design 4 fixing holes, the user can fix the extender at any position of the main unit with a cable tie
8. Exquisite and compact appearance, does not take up too much position and space
9. Equipped with a 2P to 4P PWM fan control line: 2P terminal connected to the 2-pin socket of the controller (have you noticed that the 2P interface and socket have fixed buckles, which are more secure after connection) 4P terminal connected to the CPU PWM of the computer motherboard 4-pin fan socket
10. Equipped with 10 self-locking nylon cable ties, which can be used by the user to fix the PCB, and can be used to organize and bundle the installed fan lines
11. Product list: fan extender + double-sided adhesive + PMW speed control cable + fixed cable tie

Working principle
1. The SATA15PIN interface is connected to the host power supply, and all fans are powered by the SATA interface
2. The speed control interface is connected to the motherboard CPU fan interface through a 2P to 4P cable
3. The computer CPU fan is connected to the red interface of the controller
4. The fan installed by the user can be connected to FAN1-9
5. The motherboard detects the speed of the CPU fan and adjusts the speed of all fans synchronously. Therefore, FAN1-9 does not have the feedback speed function, only the PWM speed regulation function
