USB to 4-Pin PWM 5V fan power adapter cable is designed to power 3-pin/4-pin PC case fans with USB Type-A ports. It supports both 3-pin and 4-pin fan connectors, enabling direct power supply from USB sources to cooling fans.
You will receive a 2 pack of USB to 4 Pin PWM 5V fan power adapter cables. Each cable features a USB-A connector on one end and a 4-pin PWM fan connector (3-pin/4-pin fans) on the other. The black Sleeved cable length: 30cm/11.8", Outer Diameter: 4mm, Output voltage: 5V.
This adapter offers versatile cooling solutions by converting USB power to fan compatible voltages. Key advantages include PWM compatibility, 3-pin/4-pin connector support. The sleeved case design enhances durability, while the compact size ensures easy integration into PC builds or USB-powered devices.
Connect the USB-A end to a USB port, and the 4-pin connector to your fan. Ensure the fan's starting voltage is rated voltage. For optimal cooling, pair with PWM-compatible fans and avoid overloading beyond rated power.
Only use with fans rated voltage, verify fan compatibility with 3-pin/4-pin connectors. Avoid bending the cable excessively to prevent damage to the tinned copper wires. Test with a single fan before connecting multiple devices. It can also be used with a 12V interface, but because the USB port only provides 5V, the fan speed will be slower, and the lights will be dimmer or not light up at all. This is not a product quality issue. It is recommended to use a 12V fan cable with the 12V interface.
