TeKit USB to 3/4-Pin PWM 5V Sleeved Fan Power Adapter Cable 1.6 ft

Universal USB Fan Adapter

This adapter cable lets you run any standard 3-pin or 4-pin PC cooling fan from a USB Type-A port. It delivers a fixed 5 V supply, so the fan spins at a reduced speed for quieter operation without a separate controller. The 1.6 ft length reaches nearby USB ports on routers, consoles or AV gear. All-black connectors and dense nylon sleeving give a tidy, durable finish.

Ideal for Low-Noise Spot Cooling

Builders who want a simple way to add airflow to a network switch, media box or game console will find this a plug-and-play solution. It is not suited for PC builds that rely on motherboard fan headers for temperature-based speed control or full-voltage performance. Buyers needing variable PWM curves tied to system sensors should use the standard internal headers instead.

Fixed 5 V Output Voltage

The cable supplies only 5 V to the fan, which determines the maximum speed and noise level you can achieve. This single electrical characteristic decides whether the adapter matches your cooling target or whether a motherboard header is required.
