Replacement fan for 115V equipment

The Vszerda SP103A 1123LST.GN is a 120×38mm case fan rated for 115V mains voltage at 50-60Hz. It spins at 2300 RPM and draws 11W through a dual ball bearing assembly. The unit is intended as a direct replacement for damaged cooling fans in industrial or server hardware that uses the original SUNON SP103A part number. Builders working on standard 12V PC chassis should not use this model.

Check voltage and connector before fitting

Verify that the target device supplies 115V AC at 50-60Hz and accepts a 2-pin connector. The fan dimensions are 120×120×38mm, so confirm the mounting hole pattern and clearance match the original SP103A footprint. Current draw is 0.13A at 50Hz and 0.11A at 60Hz; ensure the power source can deliver this load. Do not connect to a typical motherboard 12V header or fan controller.

Dual ball bearing runs at 2300 RPM

In normal operation the fan maintains a constant 2300 RPM, producing a steady airflow profile suited to continuous duty. The dual ball bearing design supports long-term reliability under sustained rotation. Power consumption remains at 11W, so heat contribution to the enclosure is predictable. Acoustic output is typical for a 38mm thick frame at this speed; no variable-speed or PWM control is provided.

Questions about this item

What comes in the box and do I need any extra cables or mounting hardware?

The package contains the SP103A 1123LST.GN cooling fan with its 2-pin connector already attached. Mounting screws and any additional power cables are not included and must be sourced separately.

How do I know the 2300 RPM model is the right one for my replacement?

Match the original part number SP103A 1123LST.GN and confirm the unit runs on 115 V at 50-60 Hz with a 0.13/0.11 A draw and 11 W rating. The 120×120×38 mm frame and 2-pin connector must also match your chassis cut-out.

What does the 2300 RPM rating mean once the fan is installed in my system?

At full speed the fan spins at 2300 revolutions per minute, drawing 0.13 A at 50 Hz or 0.11 A at 60 Hz while consuming 11 W. Actual airflow and noise will depend on case restriction and voltage stability.
