170 mm AC Case Fan with Dual-Ball Bearing

This 170 mm AC axial fan mounts in standard case openings and runs directly from 230 V mains power. It is intended for builders who need high-volume airflow without a low-voltage fan controller. The two-wire connection simplifies wiring for cabinet, inverter or UPS ventilation projects.

Airflow Range and Acoustic Trade-Off

At the lower speed the fan moves 340 m³/h at 50 dB(A), rising to 408 m³/h at 53 dB(A) when the motor reaches 3100 RPM. The dual-ball bearing supports continuous operation at both points, but the 53 dB(A) upper level makes it unsuitable for quiet desktop builds. Buyers who need near-silent cooling should look elsewhere.

Mains-Powered Two-Wire Interface

The fan connects straight to 230 V 50/60 Hz supply through a simple two-wire lead, drawing 46 W at 50 Hz and 44 W at 60 Hz. No PWM signal or motherboard header is required, yet the fixed-voltage design prevents speed modulation via software. Installers must provide their own switching or thermal control if variable speed is desired.

Questions about this item

Will the 170mm frame and 172×150×55mm housing fit the existing cut-out in my older server chassis?

The fan measures 172 mm wide, 150 mm tall and 55 mm deep with a 170 mm impeller, so match those dimensions against your chassis cut-out and screw-hole pattern before installing.

How can I confirm the 5E-230B is spinning at the rated 2750 or 3100 RPM once powered?

Use a tachometer or the RPM readout in your system monitoring software; the two-speed AC motor should show approximately 2750 RPM on 50 Hz and 3100 RPM on 60 Hz supply.

Does the box include mounting screws or a power cord for the bare 2-wire leads?

The unit ships as the fan motor only — mounting hardware and any mains-rated connector for the two wires must be sourced separately.
