32 cm USB-to-Fan Power Adapter

This 32 cm cable converts a standard USB-A port into a 3-pin or 4-pin female connector, letting you power a CPU or case fan from any 5 V USB source. The micro-USB-to-USB-A interface keeps the link simple and driver-free. It is aimed at builders and testers who need a quick way to spin a fan outside a motherboard header.

Suits bench testing and low-voltage fan runs

Ideal for temporary cooling setups, laptop docks or portable power banks where only 5 V is available. Not for anyone needing PWM speed control from a motherboard header. Not for installations that require a locking connector or a voltage higher than 5 V.

Micro-USB-to-USB-A connector type

The single specification that decides fit is the Micro USB to USB A connector type listed in the specifications. Match this to your power source and fan header before purchase.

Questions about this item

What voltage must the USB power source provide for this 32CM cable to run a 3-pin or 4-pin fan?

The cable passes 5 V from the USB-A end to the fan connector, so any standard USB port or charger delivering 5 V will power the fan.

Will the 4-pin female connector on this adapter accept a 3-pin fan header without modification?

Yes, the 4-pin female socket is keyed to accept both 3-pin and 4-pin fan plugs, so an older 3-pin fan fits directly.

How can I confirm the fan is receiving power through this Micro USB to USB A cable after connecting it?

The fan should spin immediately when the USB-A plug is inserted into a live 5 V port; if it does not, check the port or try another USB power source.
