AC cabinet fan for 230 V mains

The Fans Bi-Sonic 4C-230HS 12038 is a mains-powered cabinet fan designed for equipment enclosures and industrial chassis that run on 230 V AC supply. It uses an oil-bearing motor for continuous operation in server cabinets, telecom racks or similar housings. The unit is not intended for standard low-voltage PC headers and suits installers who need direct AC cooling without an external power supply.

Thermals noise and power on 230 V AC

Running directly from 230 V mains, the fan draws power from the cabinet circuit rather than a motherboard header, so system fan controllers cannot regulate its speed. The oil bearing provides steady airflow with a consistent acoustic profile suited to always-on environments. No PWM or voltage control is present, so noise and thermal output remain fixed at the factory setting for the life of the unit.

Questions about this item

How do I wire the 230 V AC fan into my case, and what step do people often miss?

Connect the two mains leads to a 230 V supply through a fused switch; the step often missed is earthing the metal frame.

What maintenance will the oil-bearing 12038 fan need later?

The sealed oil bearing is not user-serviceable; when noise or vibration increases, replace the entire fan.
