  • 70 × 70 × 15 mm footprint fits tight graphics-card spaces
  • Oil bearing rated for 50 000 hours of continuous running
  • 8 W draw at 5 V keeps power use low
  • 30 CFM airflow moves heat away from the GPU core
  • 30 dBA noise level stays quiet inside the case

Compact 70 mm cooling fan

The Vszerda AB07005HX12BB00 is a 70x70x15 mm axial fan designed for graphics-card cooling in the Tsinghua Tongfang Elite V38 chassis. It runs on a 5 V supply drawing 0.40 A for a rated power of 1.8 W. The oil-bearing motor targets a 50 000-hour service life at 30 dBA noise output.

Four-wire power interface

A 4-pin connector delivers power and allows the host board to monitor the fan, though the unit itself has no built-in RPM control. The 30 CFM airflow rating suits the original Elite V38 thermal design, so the fan fits the existing mounting points without modification. No additional brackets or adapters are required for the intended application.

Direct replacement for the Elite V38 original

This part matches the factory AB07005HX12BB00 specification, making it a drop-in swap when the stock fan reaches end of life or develops bearing noise. The upgrade is worthwhile when the original unit exceeds its rated hours or when noise rises above the 30 dBA baseline. It is not suited for builds that need higher static pressure or PWM speed regulation.

Questions about this item

Will the 1.8 W / 0.40 A draw stay within my motherboard header limit?

The fan pulls 1.8 W at 5 V (0.40 A), well under most 4-pin header ratings.

How loud is 30 dBA after hours of continuous operation?

At 30 dBA the noise is a quiet hum that stays constant because the speed is fixed.

Does the 4-pin connector need a PWM-capable header to run?

It plugs into any standard 4-pin fan header; the control line is unused so PWM is not required.
