OEM Industries MULTIFAN 4212 120mm Fan

The OEM Industries MULTIFAN 4212 is a 120mm square DC cooling fan designed for CPU air cooling applications. It operates on a 12V supply drawing 4.3W of power through a two-wire connection. This unit is intended for system builders and technicians replacing or integrating a standard 120mm fan into a heatsink or chassis. It is not for buyers who need integrated PWM speed control or addressable lighting effects.

Two-Wire 12V DC Power Interface

The fan uses a basic two-wire 12V DC interface that delivers constant voltage to the motor. Speed regulation requires external voltage adjustment because the connector lacks a PWM signal wire or tachometer feedback. This limits automatic thermal management compatibility with modern motherboard headers that expect four-pin control. Buyers needing motherboard-controlled variable speed curves should verify header compatibility before purchase.

4.3 Watt Power Draw Specification

The 4.3W power rating defines the electrical load this fan places on a 12V rail or fan header. This figure determines whether a specific motherboard header or fan controller can supply sufficient current without overload. Installers must match this draw to the header's rated output capability to ensure stable operation. It is not for builds where the available header current limit is unknown or lower than the fan's requirement.

Questions about this item

Which version of the MULTIFAN 4212 should I pick for a 120 mm mounting hole pattern?

This model is a single 120 mm square fan with a 4.3 W DC 12 V motor and two wires, so there is only one version to choose.

What does the 4.3 W rating mean once the fan is installed in my PC?

It draws 4.3 watts at 12 volts, giving a low current draw that any standard motherboard or fan-controller header can supply.

How does the 2-wire interface limit speed control on the MULTIFAN 4212?

The two-wire design provides power only, so the fan runs at a fixed speed; PWM or voltage-based speed control is not possible.
