Zyvpee 4E-115B AC 115 V Case Fan

This 120 mm by 38 mm axial fan runs on 115 V AC mains power and uses a two-pin connector. It is built with a double ball bearing for long service life in continuous operation. The all-metal frame suits industrial enclosures, server cabinets, inverter housings and custom DIY projects.

Suited for mains-powered cooling in fixed

The fan connects directly to an AC supply, so it fits equipment that already provides 115 V mains inside the chassis. Builders who need PWM speed control, low-voltage DC operation or a standard three- or four-pin motherboard header should choose a different model.

2000 to 2200 rpm airflow and noise

At full speed the fan delivers 79 to 82 CFM while producing 39 to 41 dB(A). That single operating range determines whether the cooling capacity and acoustic level match the thermal load of the target enclosure.

Questions about this item

What comes in the box and what must I buy separately?

The fan ships as a single 120 mm × 38 mm unit with a 2-pin power lead; mounting screws, fan filters or a 2-pin-to-3-pin adapter are not included.

How do I choose between the listed speed and airflow ranges?

The model runs at 2000–2200 RPM delivering 79–82 CFM; pick the higher end for maximum cooling in servers or inverters, the lower end for quieter cabinet or instrument use.

What does the 39–41 dB(A) noise rating mean once the fan is installed in a real case?

At 2000–2200 RPM the fan produces 39–41 dB(A), which is audible but not loud in a typical chassis; expect a gentle whoosh rather than a distracting whine.
