25 mm Square Micro Cooler

This 25 by 10 mm square cooler uses a NIDEC DF251R fan running on 12 V through a two-wire connection. It fits tight spaces where standard CPU coolers cannot be mounted. The black fan-only design targets small-form-factor repairs and embedded builds.

Simple Two-Wire Installation

Power connects directly to a 12 V two-pin header with no PWM or speed-control wiring required. Polarity must be observed because the connector is not keyed. The thin 10 mm profile leaves little room for cable routing, so verify clearance before securing the unit.

12 V Two-Wire Voltage Requirement

The cooler operates only from a 12 V two-wire header and has no PWM input for motherboard fan curves. Systems that supply only 5 V or use four-pin PWM headers will not run this fan correctly. Confirm the header type before purchase.

Perguntas sobre este artigo

How can I confirm the DF251R 25x10mm fan is spinning correctly after connecting the 2-wire 12V power?

After powering on, visually verify the black 25mm blades rotate steadily and listen for smooth airflow without clicking or vibration from the NIDEC micro cooler.

What components are included with the DF251R and what must be sourced separately?

The box contains the square NIDEC DF251R 12LLA-01 fan unit only; mounting screws, thermal paste and any required 12V power adapter or header cable are not included.

Which DF251R version should I choose for a 12V 2-wire header?

Select the DF251R 12LLA-01 model — it is the sole 12V 2-wire variant listed, matching a standard 2-pin motherboard or controller header.
