Compact 12 V 70 mm fan for tight builds

The AVC C7015B12M is a 70 x 70 x 15 mm DC fan that runs on 12 V and draws 0.20 A for 2.4 W of input power. Its dual-ball bearing spins at 3800 RPM to deliver 23.2 CFM of airflow while producing 34.5 dBA of noise. The three-pin connector supplies a tachometer signal for speed monitoring.

Replaces worn 70 mm coolers when dual-ball

Swap this unit in when an existing 70 mm sleeve-bearing fan has become noisy or seized after extended use. The jump is worth it if the original cooler cannot be lubricated and the chassis has no room for a larger frame. Builders who need higher static pressure or PWM control should look elsewhere.

  • Compact 70 mm frame fits tight build spaces
  • Dual ball bearing runs at 3800 RPM for long service life

Questions about this item

What are the exact mounting-hole dimensions for the 70 mm square frame?

The fan measures 70 mm on each side with a 15 mm thickness, so mounting holes follow the standard 70 mm square pattern.

How do I connect the 3-pin lead to a motherboard header without losing speed control?

Align the keyed 3-pin connector with the 12 V, ground and tach pins on the motherboard header; the board regulates voltage to vary the 3800 RPM speed.
