Compact 12V axial fan for tight builds

This Nidec D04G-12TS1 moves air in a 40 by 40 by 20 millimetre frame. It suits small-form-factor cases or equipment bays where larger fans will not fit. The 12 volt supply matches standard headers on most motherboards and fan controllers. Builders needing higher airflow or quieter operation at the same voltage should look elsewhere.

Limited by 40 millimetre footprint

The 20 millimetre thickness restricts static pressure, so the fan works best with unrestricted intake or exhaust paths. Only 12 volt operation is specified; speed control depends entirely on the host header capabilities. No PWM or tachometer signals are mentioned, so automatic curve management may not be possible. Buyers who need variable-speed feedback or higher static pressure must choose a different model.
