Compact 40mm form factor

The OEM Industries FD1240-D2233A is a 40 by 40 by 10 millimetre axial fan designed for tight chassis where a full-size cooler cannot fit. It draws 0.11 amps at 12 volts through a standard three-pin connector and uses a ball bearing for durable rotation. Black frame and blades keep the appearance neutral for any build.

Sustained low-speed operation

Ball-bearing construction maintains consistent RPM during continuous duty without the wear pattern seen in sleeve alternatives. The modest current draw produces a steady airflow suited to component-level cooling rather than high-wattage processor loads. Acoustic output remains proportional to the low rotational speed required for small-form-factor enclosures.

Three-pin voltage control limit

The three-pin interface adjusts speed by varying supply voltage, so minimum RPM is bounded by the motherboard's lowest voltage step. Pulse-width modulation is not available, preventing software-defined curves below that hardware floor. Builders needing finer low-speed granularity or automated profiles must verify board capabilities before purchase.

Perguntas sobre este artigo

How loud and warm does the 40mm ball-bearing fan run at 12V 0.11A during continuous operation?

The 40×10mm ball-bearing fan draws 0.11A at 12V, so power draw is low; ball bearings typically run quieter and cooler than sleeve types over long periods.

What connector and voltage must my motherboard or fan header provide for this 3-pin 12V cooler?

It uses a standard 3-pin 12V connector; your board needs a 3-pin fan header supplying 12V to power and report speed.

Will the 40×10mm footprint fit alongside taller RAM or a legacy socket retention bracket I already have?

At 40×40×10mm the unit is very compact, leaving ample clearance for tall memory modules and older socket brackets.
