SKU CH-3CFA-EC5N9

A 5 V, 0.82 A four-wire server cooler fan for targeted chassis airflow

  • 5 V DC input ensures stable server operation
  • 82 A current draw balances airflow with power efficiency
  • 4-wire PWM control enables precise speed regulation
  • New condition guarantees reliable out-of-the-box performance

Server Cooling Fan for 5V Systems

This 4-wire cooler fan is built for server chassis and compatible enclosures that require a 5V DC power supply. It suits administrators maintaining hardware that uses the BAZA0920R5U form factor and part numbers 863669-102 or 863656-003. The unit is new and ready for installation in supported bays.

Low-Voltage Operation and PWM Control

Running at 5V with a 0.82A current draw, the fan keeps power consumption modest while the 4-wire interface enables pulse-width modulation for speed regulation. This allows the system to balance airflow against acoustic output under changing thermal loads. The design targets steady cooling in dense server environments.

Highlights

  • 5 V DC input ensures stable server operation
  • 82 A current draw balances airflow with power efficiency
  • 4-wire PWM control enables precise speed regulation
  • New condition guarantees reliable out-of-the-box performance

Questions about this item

How do I install the BAZA0920R5U fan and what is the common wiring mistake?

Connect the 4-wire plug to a 5V header matching the .82A draw; the step often missed is aligning the keyed connector so the PWM wire sits on the correct pin.

What maintenance will the 863669-102 cooler fan need later?

Plan to clean dust from the blades every few months and listen for bearing noise; if the rotor develops play or speed drops, replace the unit.
