Compact 40 mm Maglev cooler

The OEM Industries KD1204PKS2 is a square 40 mm fan designed for tight CPU cooler mounts in small-form-factor or embedded systems. Maglev bearing operation keeps noise and wear low while the 12 V, 0.9 W draw suits limited power budgets. Builders working with proprietary server trays or thin clients will find the footprint familiar. It is not aimed at full-size desktop towers that expect larger heatsink assemblies.

Two-wire power simplicity

A two-wire lead delivers power without PWM or tachometer signals, so speed control relies on voltage regulation from the motherboard or an external controller. The bare-lead connector fits cramped headers where three- or four-pin plugs would foul adjacent components. Black frame and blades blend into dark chassis interiors. Systems that require fan-fault reporting or closed-loop speed curves cannot use those features with this unit.

Fixed-speed 12 V operation

Running at a constant 12 V means airflow and acoustic output stay steady rather than ramping with load. The 0.9 W rating indicates modest static pressure suited to low-impedance heatsinks or case ventilation rather than dense fin stacks. No LED lighting or additional wiring is present. Environments needing variable airflow or higher static pressure will need a different cooling approach.

Otázky k tomuto produktu

What voltage and power draw does the 2-wire connector expect?

The fan runs on 12 V and draws 0.9 W through its two-wire lead.

Will this 40 mm square cooler fit my mounting holes?

It follows the 4020 form factor — 40 mm square — so it matches standard 40 mm mounting patterns.

How do I connect the two-wire lead without a PWM header?

Plug the two wires directly into a 12 V DC header or adapter; there is no PWM signal wire to manage.
