Ultra-thin 25mm DC fan

The OEM Industries AD0205MB-k50 is a compact square cooler measuring 25mm across and designed for tight spaces. It runs on a 5V supply drawing only 0.09A through a simple two-wire connection. The ball-bearing motor targets embedded systems, small-form-factor PCs and replacement cooling where height clearance is minimal.

Drop-in two-wire installation

Mounting uses the standard four-corner holes on the 25mm frame so it fits existing cut-outs without adapters. The two-wire lead carries power only, so speed control or monitoring requires an external circuit. Polarity must be observed on the 5V line; reversing the wires will prevent the fan from spinning.

Low airflow for spot cooling

At 1600–1999 rpm the fan delivers 1–5 cfm with a noise level of 25–30 dBA, suitable for chipset heatsinks, VRM arrays or single-board computers. It cannot move enough air for a modern CPU socket under sustained load, so builders needing higher static pressure or greater volume should choose a larger cooler.

Questions sur cet article

How can I confirm the AD0205MB-k50 is spinning correctly after installation?

Listen for quiet operation between 25 and 30 dBA and verify the RPM reads between 1600 and 1999 in your monitoring software.

What comes with the AD0205MB-k50 and what must I source separately?

The package includes the 25 mm ball-bearing fan with a two-wire 5 V 0.09 A lead; mounting screws and any PWM controller are not supplied.

Which version of the AD0205MB-k50 should I choose for my build?

Only the single 5 V 0.09 A ball-bearing model in black is offered; select it when you need a 25 mm ultra-thin cooler with 1 to 5 CFM airflow.
