Zyvpee SJ1238HA2 120×38 mm 220 V AC case fan

120×38 mm 220 V AC case fan

The Zyvpee SJ1238HA2 is a 120 mm by 38 mm axial fan designed for cabinet or chassis ventilation. It operates directly from 220 V mains power through a two-wire connection, removing the need for a separate DC supply or motherboard header. The non-LED black frame suits industrial enclosures, server cabinets or workstations that require simple, reliable airflow.

Sustained mains-powered airflow

Because the motor runs on AC line voltage, its speed and airflow remain constant as long as power is present, unaffected by PWM duty cycles or voltage droop on a 12 V rail. The two-wire interface provides no speed feedback or control, so the fan delivers a fixed cooling capacity continuously. This makes it suitable for environments where unattended, steady-state thermal management is preferred over variable-speed tuning.

Replaces legacy 120 mm AC axial fans

The SJ1238HA2 serves as a drop-in replacement for existing 120×38 mm 220 V AC fans in legacy enclosures, rack trays or power-supply modules. The jump is worthwhile when the original unit has worn bearings, reduced airflow or failed entirely and a direct mains-powered substitute is required. It is not suited for builders who need PWM speed control, motherboard monitoring or low-voltage DC operation.
