Compact 40 mm case fan

The OEM Industries 4020H12S is a 40 mm sleeve-bearing fan designed for tight spaces in small-form-factor builds or as a replacement cooler on legacy hardware. It runs on 12 V and draws 0.07 A through a simple two-wire power connection. No LED lighting is included, keeping the unit plain for utilitarian installations. The black finish blends with most chassis interiors.

Two-wire power and minimal clearance

The fan connects directly to any 12 V two-pin header or adapter, so it needs no PWM control or additional controller hardware. Its 40 mm frame fits narrow mounting points where larger fans cannot sit, freeing up room around compact motherboards or low-profile coolers. Builders who need variable speed control or a three-pin tachometer signal should look elsewhere, as this model provides only fixed-voltage operation.

Sleeve bearing acoustics and low draw

The sleeve bearing keeps running noise modest at idle but may become audible over time as the lubricant ages. Power consumption stays at 0.07 A, adding negligible load to the system’s 12 V rail. Thermal performance suits light-duty airflow tasks such as chipset heatsinks or memory modules rather than high-wattage CPU cooling.

Questions about this item

What is the maximum continuous current draw of the 4020H12S fan under sustained load?

The fan draws 0.07 A at 12 V, so sustained current remains at that level.

How much acoustic noise does the sleeve bearing generate when the fan runs all day?

The sleeve bearing runs at a low 12 V 0.07 A rating, keeping operational noise minimal during extended use.

Which power header must the motherboard provide for the 2-wire connector to work?

A standard 12 V two-pin fan header supplies the required voltage and ground for the 4020H12S.
