SKU CH-5ST7-33098

70 mm DC 5 V USB-powered case fan with plastic frame for computer cooling

  • 70 mm frame fits tight enclosures
  • 5 V DC operation keeps energy draw low
  • Ultra-silent running suits quiet environments
  • Plastic housing reduces weight and vibration

Compact USB-powered 70 mm case fan

The SXDOOL 7015MB05B is a 70 mm DC fan that draws 5 V power from a standard USB port, making it suitable for small-form-factor cases, router enclosures or any device with a spare USB socket. Its two-wire design keeps cabling simple for DIY cooling upgrades.

Sustained low-speed airflow

Running continuously from a USB supply, the fan maintains a steady airflow without the spin-up spikes seen on PWM-controlled 12 V units, so temperatures in tight enclosures stay stable during long sessions. The plastic frame and blade assembly are built for constant operation at the rated voltage.

Tool-free USB mounting

The USB plug lets you power the fan from a router, NAS or PC front panel without opening the case to reach a motherboard header, while the 70 mm footprint fits common mounting holes on compact chassis and network gear. No additional adapters or soldering are required.
