Compact 35 mm DC Cooler

The OEM Industries 1406KL-04W-S30 is a 35 mm square DC fan designed for targeted CPU or chassis cooling. It suits builders working with confined layouts or replacing an identical NMB 3515 unit. The three-pin connector provides basic speed reporting without PWM control.

Three-Pin Voltage Control Limits

Speed is regulated by varying the 12 V supply voltage, so the motherboard or controller must support voltage-mode adjustment. The 0.11 A draw keeps load minimal, but the lack of a fourth PWM wire means precise low-speed curves are not possible. Headers locked to PWM-only operation will not drive this fan correctly.

Black Frame with Three-Wire Lead

The black plastic frame houses the 35 mm rotor and terminates in a standard three-pin plug for direct header connection. No LED lighting is present, keeping the unit visually neutral. Mounting relies on the four corner holes common to 35 mm square fans, so verify hole spacing matches the target bracket before installation.

Questions about this item

Should I pick the 35 mm square version or a larger frame?

The unit is a 35 mm square frame with a 15 mm thickness, so it fits only mounts cut for that exact footprint.

What does the 0.11 A rating mean once the fan is running in my PC?

At 12 V the fan draws 0.11 A, giving very low power use and quiet operation for small-form-factor builds.

How does the 3-pin connector limit speed control?

The 3-pin header supplies constant 12 V; speed varies only by voltage changes from the motherboard, not by PWM signalling.
