120 mm axial fan for 230 V AC mains, 1800 rpm, 45 dB, 38 mm thick, two-pin BTH connector

  • Reliable 230 V AC operation from the 4715FS-23T-B50 axial design
  • Compact 120 x 120 x 38 mm frame fits standard 12038 mounting points
  • Quiet 45 dB noise level at 1800 rpm for effective air cooling
  • Simple 2-pin BTH connector enables quick installation
  • Brand-new condition ensures original performance for replacement or new builds

Direct replacement fan

The Vszerda 4715FS-23T-B50 is a 120 mm axial fan designed to replace a failed NMB unit in industrial or server equipment. It operates on 230 V AC mains power at 50/60 Hz and fits the standard 120x120x38 mm mounting pattern. The black frame and 2-pin BTH connector match the original specification for a straight swap.

Mains-powered thermal profile

Running at 1800 rpm the fan draws 0.09 A at 50 Hz and 0.08 A at 60 Hz, delivering forced-air cooling with a declared noise level of 45 dB. Because it connects directly to AC supply, no separate DC power supply or motherboard header is required, simplifying wiring in rack enclosures or standalone appliances.

Drop-in hardware only

The package supplies the fan unit itself with its factory-fitted 2-pin BTH lead; no mounting screws, speed-control cable or monitoring software are included. Installers must reuse existing fixings or source compatible hardware separately, and speed is fixed by line frequency rather than PWM or voltage control.

Questions about this item

How do I install the 2-pin BTH connector on the 120x120x38 mm fan, and which step is often missed?

Align the keyed 2-pin BTH plug with the header on your chassis or power supply, press firmly until it clicks, then verify the 1800 rpm spin-up; the step often missed is confirming the connector is fully seated so both pins make contact.

What maintenance will the 4715FS-23T-B50 need over time?

Expect to clean dust from the blades and frame periodically; the sleeve bearing is not user-serviceable, so when noise rises above the rated 45 dB or speed drops below 1800 rpm, replace the entire 12038 unit.

What limit appears first when the fan runs continuously at 230 V AC 50/60 Hz?

The sleeve bearing’s thermal limit is reached first; sustained operation at 45 dB and 1800 rpm gradually degrades lubricant, leading to increased noise and reduced speed before any electrical component fails.
