SKU CH-9WMX-DJAJW

A 5 V USB-powered cooling fan with a protective sleeve for routers, TV boxes or desktop components

  • USB powered — runs from any 5 V port
  • Ball-bearing motor — smoother rotation and longer life
  • Protective net included — guards fingers and cables
  • Fits routers, TV boxes and desktop cases

Compact USB-Powered Router Fan

This 5V USB cooling fan fits routers, TV boxes and similar desktop devices. A protective net covers the blades and a ball-bearing sleeve reduces operating noise. The unit draws power directly from any standard USB-A port so no external adapter is required. Its small footprint allows placement inside tight enclosures or on crowded shelves.

DIY Cooling for Low-Power Network Gear

The fan suits hobbyists adding airflow to a router, streaming box or single-board computer that already has a free USB socket. It is not intended for high-heat components such as CPUs or GPUs, nor for builds that lack a USB-A power source. Buyers needing variable speed control or larger airflow volumes should consider alternative cooling solutions.

Highlights

  • USB powered — runs from any 5 V port
  • Ball-bearing motor — smoother rotation and longer life
  • Protective net included — guards fingers and cables
  • Fits routers, TV boxes and desktop cases

Questions about this item

Is the USB plug the only way to power the fan?

Yes, the fan draws 5 V from any standard USB-A port on a router, TV box or computer — no separate adapter is required.

How much airflow should I expect from the 5 V USB fan inside a router case?

At 5 V the motor spins fast enough to move a steady stream of air through the protective net, lowering internal temperatures by several degrees in typical router or TV-box enclosures.
