5V USB Fan Power Cable

This cable connects a 5 V chassis fan to any standard USB port so the fan can draw power without a motherboard header. It is intended for builders who want a simple way to add spot cooling inside a case or to run a small fan on a router, set-top box or similar device.

Builders needing motherboard-controlled fan curves

The cable provides fixed 5 V power only, so fan speed cannot be regulated by the system. Users who require PWM control, voltage regulation or a traditional 3-pin or 4-pin header connection should look for a different adapter.

Questions about this item

Will the 5 V USB plug power a chassis fan that currently runs from a 3-pin motherboard header?

No, the cable delivers 5 V over USB-A only; it cannot connect to a 3-pin or 4-pin PWM fan header on the motherboard.

How can I confirm the cable is supplying power to the fan once it is connected?

Plug the USB-A end into a live 5 V port and verify the fan spins; if it remains still, try another USB port or check the fan's own power requirements.
