Fans 4020 12V 0.20A case fan

SKU CH-YS1M-5TDW0

A compact 4020 case fan running on 12 V at 0.20 A for tight server or switch chassis

  • Compact 1U fit for tight server chassis
  • 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.

Highlights

  • Compact 1U fit for tight server chassis
  • 12 V operation matches standard power rails
  • Low 0.20 A draw keeps power budgets lean
  • 4020 form factor suits space-constrained builds

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.
