Compact 50mm Fan for Tight Builds

This 50mm square cooler from NMB suits small-form-factor systems and embedded boards where height is restricted. The 15mm profile and three-pin connector fit standard headers without adapters. It is not for builders who need higher airflow or larger heatsink clearance.

Straightforward Three-Pin Install

The 3-pin power connector plugs directly into most motherboard or controller headers. Ball bearing construction reduces the risk of sleeve wear over time. No LED wiring or PWM cable is present, so speed control depends on voltage regulation. Misaligned mounting holes are the usual issue when brackets differ from the 50mm pattern.

12V 0.1A Draw Defines Compatibility

The cooler draws 0.1A at 12V, a figure that determines whether a given header or fan controller can supply enough current. Exceeding the header rating can cause instability or shutdown. Check the board specification against this draw before fitting.

Questions about this item

How can I confirm the 2106KL-04W-B39 fan is spinning correctly after connecting the 3-pin header?

Check that the fan blades rotate steadily and listen for smooth ball-bearing operation; the 12 V, 0.1 A rating means it should start immediately when the motherboard supplies power.

What comes in the box with the NMB 5015 cooler and what extra parts are needed?

The package contains the 50 mm square fan with a 3-wire 3-pin connector; no mounting brackets, screws or thermal paste are included, so you must supply those separately.

Which version of the 50 mm 15 mm cooler should I choose for a standard 3-pin CPU header?

The 2106KL-04W-B39 model is the only version listed; it matches a 12 V, 0.1 A, 3-pin header directly, so no alternative capacity or voltage option is required.
