Fans 12038 12cm VA450DC V34809-90 3.3A 4-wire double ball bearing case fan

SKU CH-QJ2N-DP4R6

A 12 cm case fan with 4-wire PWM control, double ball bearings and a 3.3 A current draw for high-airflow cooling

  • 4-wire PWM control for precise speed adjustment
  • Double ball bearing design for extended operational life
  • 3 A current draw delivers high airflow performance
  • 12038 form factor fits standard 12 cm mounting points

12038 12 cm 4-wire high-current fan

This 12038 frame fan draws 3.3 A on a 4-wire PWM interface and uses double ball bearings for long service life. The VA450DC V34809-90 model is built for high static pressure in dense chassis or rack enclosures. It suits builders who need maximum airflow from a standard 12 cm mounting pattern.

Best for servers and workstations that can supply

Not for systems with standard 1 A or lower fan headers that cannot deliver the required current. Buyers needing quieter low-speed operation should look at lower-amperage alternatives. Installers without 4-wire PWM control will lose speed regulation.
