Ruth's sister 300705 30mm 5V ultra thin mute micro fan international power cord

SKU CH-X38W-0Y9XP

Two ultra-thin 30 mm 5 V micro fans for set-top boxes or moxibustion instruments

  • Ultra-thin 7 mm profile fits tight device spaces
  • 5 V operation runs from standard USB or low-voltage rails
  • Mute bearing keeps set-top boxes and therapy tools quiet
  • Two fans included for immediate dual-point cooling

5V ultra-thin micro fan for compact cooling

Two DFS300705H fans measure 30 by 30 by 7 millimetres and run on 5 volts. They are designed for tight spaces such as set-top boxes or small instruments where airflow must stay quiet.

Simple two-wire connection suits basic 5V headers

Polarity must be matched to the supply or the fan will not spin. The ultra-thin frame leaves no room for mounting screws, so adhesive or a custom bracket is usually required.

Questions about this item

How do I confirm the 30mm 5V fan is running quietly after installation?

Power the DFS300705H and listen for low airflow noise; the ultra-thin 30×30×7 mm frame should spin without audible vibration in a set-top box or moxibustion instrument.

What comes in the package and what must I source separately?

The box contains two DFS300705H 30mm 5V micro fans; you will need to provide a 5V power source and any mounting hardware or connectors required by your device.
