Gebildet 2-Pack USB to 3-Pin/4-Pin Case Fan Power Adapter

Easily power your computer fans using any standard USB port with the Gebildet 2-pack adapter cable set. This solution allows you to convert a 5V USB connection into a 3-pin or 4-pin fan connector, making it simple to add extra cooling to your setup without needing a dedicated motherboard header. Each cable features a built-in on/off switch, giving you immediate control over your fan speed and power usage at any time. These 30cm sleeved cables are designed for convenience and versatility. If you use 12V fans, they will operate at a reduced 5V voltage, which is ideal for achieving quieter, silent operation. This makes them a great choice for users looking to minimize noise in their workspace or small electronics projects. Please note that because these cables use a two-wire system (positive and negative), they do not support tachometer speed sensors or PWM speed control functionality. Ensure your fan has a start voltage at or below 5V for reliable performance.
