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.

Questions about this item

How loud and warm does the Zyvpee SJ1238HA2 get when it runs continuously?

It is an AC axial fan that spins directly from 220 V mains, so expect typical mains-fan hum and exhaust heat proportional to the airflow it moves through the case.

What power connection must my case already provide for the two-wire 220 V plug?

The fan terminates in two bare wires for 220 V AC; your enclosure needs a matching mains-voltage feed or an internal terminal block wired to the same supply.

Will the 120×38 mm frame line up with the mounting holes on my older 120 mm fan positions?

Yes, the 120 mm square footprint matches legacy 120 mm mounting patterns, while the 38 mm thickness simply occupies more depth inside the panel.
