Server cooling fan pack

This lot contains twenty 80x38mm axial fans rated at 12V and 6.1W each. They use a 4-wire PWM connector for speed control and ball bearings for durability. The units are designed for server, inverter, UPS or DIY applications requiring forced airflow. Each fan spins between 5000 and 5499 RPM with a noise level of 40 to 45 dBA.

Build integration and clearance

The 80x80x38mm frame fits standard 80mm mounting points in server chassis or equipment racks. Four-wire PWM allows the motherboard or fan controller to regulate speed automatically based on temperature. This reduces cable clutter compared to 3-wire designs and frees up headers for other devices. Ball bearings tolerate orientation changes and vibration common in rackmount environments.

Sustained load behaviour

At continuous speeds of 4750 to 5550 RPM the fans maintain airflow without the wear associated with sleeve bearings. Acoustic output stays within the 39 to 47 dB(A) range during prolonged operation. The 12V 6.1W power draw per unit remains stable under constant load, simplifying power budget calculations for dense configurations.
