SKU CH-M3E4-XVXTD MPN 3656Size

A 92 mm square, 38 mm deep AC axial fan running on 230 V mains and delivering 75-80 CFM at 37-42 dBA

  • Airflow rate75-80 CFM
  • High airflow at 75-80 CFM for effective cooling
  • Quiet operation at 37-42 dBA noise level
  • 230V AC power with low 11-12W consumption
  • Wide -40 to 130°C operating temperature range
  • 60,000-hour service life for long-term reliability

Purpose-built AC axial fan for industrial airflow

This 92 mm square AC axial fan runs directly from 230 V mains and delivers 75-80 CFM for high-volume air movement. It suits equipment cabinets, heat-exchanger ducts and server chassis that need steady throughput without a separate DC supply. Builders who require PWM speed control or a 12 V connector will need a different product.

Capacity and headroom: 75-80 CFM at two speed steps

At 2700 RPM the fan moves 75 CFM (75 m³/h) drawing 11 W and 0.065 A; at 3200 RPM it reaches 80 CFM (89 m³/h) drawing 12 W and 0.07 A. The dual-speed curve gives headroom for peak thermal loads while idling lower for routine operation. Systems demanding sustained flow above 80 CFM or variable-speed profiles beyond the two fixed points fall outside its range.

Thermals, noise and power in normal use

Operating between 37 dBA at low speed and 42 dBA at high speed, the fan stays quiet enough for rack environments while moving rated volume. Power draw stays at 11-12 W across the range, and the design is rated for 60000 hours at ambient temperatures up to 130 °C. Installations needing near-silent acoustics below 35 dBA or DC-voltage operation are not served by this unit.

Questions about this item

Will the 230 V fan run safely alongside my older 12 V case fans?

No, this unit requires 230 V AC mains power while typical PC case fans use 12 V DC; they cannot share the same fan header or controller.

How can I confirm the 3656 is spinning at the rated 2700 or 3200 RPM after installation?

The motor provides a tachometer output; connect that signal to a motherboard fan header or external RPM meter to verify the speed matches the 2700/3200 RPM specification.

Does the box include a power cord or mounting screws for the 92 mm frame?

The supplier data lists only the axial fan unit itself; a 230 V power lead and 92 mm mounting screws must be sourced separately.
