Delock USB Type-A Male to 2 x 4 Pin Fan Connector Cable with On/Off Switch, 1 m, Black

System builders and modders often need extra cooling for components like memory, VRMs, or chipset heatsinks, but motherboard fan headers are limited. This Delock fan cable solves that by letting you power two PC fans from any USB Type-A port. The integrated on/off switch gives you instant control over fan operation without unplugging the cable.

Key specifications

• Input connector: 1 x USB Type-A male
• Output connectors: 2 x 4-pin fan connectors (male, 2 pins occupied: power and ground)
• Cable length: 1 m
• Output voltage: 5 V DC from USB port
• Integrated on/off switch for manual fan control
• Compatible with 3-pin and 4-pin PC fans (power only, no speed control or monitoring)
• Plug & Play – no drivers required
• Colour: Black, PVC jacket

Why choose it

This cable provides a simple, clean way to add extra cooling to your system. USB ports are always available, and the switch gives you instant control over fan noise and airflow. The two fan connectors let you power a pair of fans from a single USB port, reducing cable clutter.

Ideal use cases

• Cooling additional components in a PC case where motherboard fan headers are limited
• Powering fans in external enclosures, test benches, or DIY projects
• Adding a manual fan switch to control noise during light workloads
• Powering small fans for cooling routers, set-top boxes, or other electronics with USB ports

Good to know

The cable provides power only; it does not transmit fan speed signals. Fans will run at full speed when the switch is on. Ensure your USB port can supply sufficient current for the fans you connect.
