New Ocean Tech for delta THA0412BN 12V Fan 40x40x28mm

SKU CH-DAXZ-Q5HH2

Compatible replacement fan for Delta THA0412BN 12V 40x40x28mm cooling applications

  • 12 V operation for efficient cooling
  • 40 mm square frame fits compact builds
  • 28 mm thickness for slim profiles
  • Designed for Delta THA0412BN compatibility
  • First listed by manufacturer in 2026

Purpose and audience

This 12 V fan is designed as a direct replacement for the Delta THA0412BN model. It suits technicians and hobbyists who need to restore airflow in compact equipment that originally shipped with this specific part.

Build fit and clearance

The unit measures 40 by 40 by 28 mm, matching the footprint and thickness of the reference fan. It mounts in the same screw pattern and connects to the existing 12 V header, freeing the builder from adapter cables or bracket modifications.

Upgrade context

It replaces a worn or noisy Delta THA0412BN without changing voltage or dimensions. The swap is worthwhile when the original fan has failed or developed bearing noise, and the equipment chassis cannot accommodate a different frame size.

Questions about this item

What is the maximum continuous current the 12V fan draws under sustained load?

The fan is rated for 12V operation and carries the model designation THA0412BN, which indicates a 12V DC brushless design for delta-style cooling.

How much acoustic noise and heat does the 40x40x28mm frame produce during all-day operation?

The compact 40x40x28mm housing limits airflow to low-volume delta cooling, so acoustic output and exhaust heat stay minimal in continuous use.

Which power connector or header must the system already provide for this 12V delta fan?

The unit requires a standard 12V DC two-pin or three-pin fan header capable of supplying the rated voltage for the THA0412BN model.
