Black 120 mm square case fan with PWM cable and mounting holes

Fans

Fans 12038 PWM 3.3A 12V 12CM VA450DC V34809-35

SKU CH-4MV5-8FBVW

A 12 cm PWM case fan delivering 3.3 A at 12 V for high-airflow cooling

  • PWM control adjusts speed to match cooling demand
  • High 3.3 A current delivers strong airflow for demanding builds
  • 12 V operation fits standard desktop power rails
  • 120 mm frame fits common case mounting points

High-current 12038 PWM fan for dense builds

This 12 V case fan draws 3.3 A through a PWM circuit, targeting systems that need concentrated airflow in a 12038 frame. It suits servers, workstations or custom loops where a single high-pressure unit replaces multiple lower-speed fans. Buyers who want quiet, low-RPM cooling or who lack a 4-pin header should look elsewhere.

Installation fits standard 120 mm mounting holes

The four-pin connector plugs directly into a motherboard or fan-controller PWM header; no adapters are required. What usually goes wrong is under-specifying the header — many consumer boards limit each header to 1 A, so this 3.3 A unit can trip protection or melt the connector if run at full duty without a dedicated high-current header or external relay.

Questions about this item

How can I confirm the 12038 PWM fan is running at the correct 3.3A current draw after installation?

Use a multimeter in series with the 12V supply line to measure current draw; it should read near 3.3A at full PWM duty cycle.

What is included with the VA450DC V34809-35 fan and what must be sourced separately?

The fan unit itself is supplied; mounting screws, PWM cable extensions or fan controllers are not included and must be purchased separately.
