SKU CH-83Q0-DXET4

A 12 V, 0.13 A, three-wire mute CPU fan for compact cooling

  • 12 V power for stable operation
  • 13 A draw keeps energy use low
  • three-wire design enables speed monitoring
  • mute profile reduces audible noise

Compact 12 V case fan for tight builds

This 40 mm square fan runs on 12 V and draws 0.13 A, making it suitable for small-form-factor chassis or replacement cooling in legacy hardware. The three-wire connection provides tachometer feedback so the system can monitor rotational speed.

Three-wire tachometer interface

The 3-line cable supplies power, ground and a speed signal, allowing motherboard headers or fan controllers to report RPM. Buyers who need PWM speed control or a four-pin connector should look elsewhere, as this unit only supports voltage-based regulation.

Questions about this item

What does the 0.13 A current draw mean for my motherboard fan header?

The fan draws 0.13 A at 12 V, so a standard 1 A header can power several of these units in parallel.

How does the three-wire connection affect speed reporting?

The third wire provides a tachometer signal so the board can monitor RPM, but voltage control is still required to change speed.
