A compact 70x70x15 mm box fan delivers 30 CFM airflow at 30 dBA while drawing 1.8 W from a 5 V supply

  • TypeDecorative Boxes
  • 50 000-hour oil-bearing life for long-term reliability
  • 30 CFM airflow at only 30 dBA for quiet cooling
  • Compact 70 × 70 × 15 mm frame fits tight spaces
  • 5 V 0.40 A 1.8 W draw keeps power use low
  • Four-pin connector enables direct graphics-card power

Compact 5 V box fan for graphics-card cooling

The NO. AB07005HX12BB00 is a 70 x 70 x 15 mm decorative box fan designed to mount on a graphics card. It runs from a 5 V four-pin header and draws 0.40 A, making it a straightforward drop-in for the Tsinghua Tongfang Elite V38 chassis or similar tight builds.

Oil-bearing motor rated 30 dBA at 1.8 W

The oil bearing delivers 30 CFM airflow while the motor consumes 1.8 W and produces 30 dBA in normal operation. Rated life is 50 000 hours, so the fan maintains consistent cooling and acoustic levels over extended daily use without speed control circuitry.

Four-pin 5 V power; no RPM control needed

Connection is a standard four-pin 5 V header, so the unit draws power directly from the graphics card or motherboard without an extra adapter. The 15 mm thickness fits slim clearances, while the fixed-speed design removes the need for fan-curve tuning in the host system.

Questions about this item

How do I connect the 4-pin power interface on this 70x70x15mm fan?

Plug the 4-pin connector directly into a 5V 0.40A header; the keyed design prevents reverse insertion, which is the step most people get wrong.

What maintenance does the oil bearing require during its 50000 hrs rated life?

The oil bearing is sealed and requires no lubrication; replacement is needed only when airflow drops below 30CFM or noise exceeds 30dBA after the rated hours.

At what point does the 1.8W power limit throttle sustained airflow?

The fan runs at a fixed 1.8W draw, so airflow stays at 30CFM continuously; the first limit reached is the 50000 hrs bearing life, not thermal throttling.
