SKU CH-5YQ5-3A2ZM

A compact 4020 case fan running at 12 V and 0.18 A for targeted chassis airflow

  • 12 V power for stable operation
  • 18 A draw keeps energy use low
  • 4020 form factor fits tight chassis spaces
  • First listed by the manufacturer in 2021
  • New condition guarantees full service life

4020 12V case fan for compact builds

The 4020 frame fits tight chassis locations where larger fans cannot be mounted. It runs on a standard 12 V supply and draws only 0.18 A, making it suitable for low-power auxiliary cooling. Buyers who need higher airflow or larger diameter fans will find this model insufficient.

Mounts in 40 mm slots with two-wire power

The fan connects directly to a 12 V header or Molex adapter using its two-wire lead. No PWM control or tachometer signal is provided, so speed is fixed by voltage. Builds requiring automatic speed curves or fan monitoring must use a different solution.

Moves air for targeted spot cooling

At 0.18 A the motor delivers modest static pressure for heatsinks, VRM zones or drive cages. It handles light thermal loads in small enclosures but runs out of capacity on high-TDP components or dense radiator stacks.

Questions about this item

How long can the 12 V 0.18 A motor run before heat becomes the limiting factor?

The fan draws 0.18 A at 12 V, so sustained operation is limited by the motor's thermal design rather than a published duty-cycle figure.

What noise and heat levels should I expect when this 4020 fan runs continuously?

At 12 V the unit moves air quietly for its size; expect a low hum and only slight warmth on the frame during all-day use.

Which connector or mounting hardware must I already have to install this 4020 cooling fan?

You need a standard 12 V two-pin or three-pin header and 40 mm mounting holes or brackets that match the 4020 footprint.
