  • 12 V operation matches standard power rails
  • Low 0.20 A draw keeps power budgets lean
  • 4020 form factor suits space-constrained builds

Compact 12 V 4020 case fan

This 40 mm square fan runs on 12 V and draws 0.20 A, making it suitable for tight 1U server and network-switch chassis. Its slim profile fits where larger coolers cannot, providing targeted airflow for dense equipment racks.

Two-wire power lead only

The unit ships with a bare two-wire connector, so speed control or monitoring requires a motherboard header or fan controller that supports voltage regulation. Builders needing PWM signalling, tachometer feedback or mounting screws must source those separately.

Questions about this item

How often will the 12 V 0.20 A 4020 fan need cleaning or bearing replacement?

Dust buildup on the blades is the main maintenance; clean with compressed air every few months. The sleeve bearing is not user-serviceable, so plan to replace the whole fan when noise or vibration appears.

What limit appears first when the 12 V 0.20 A 4020 fan runs continuously in a 1U server?

The sleeve bearing’s temperature rating is the first constraint; sustained heat in a dense 1U chassis accelerates wear and eventually causes speed drop or noise.
