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.

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.
