TSUJ Kepler-C72J-OYS-0339 6038 6cm 12V 1.20A 2-Wire Cooling Fan

Compact 12 V Cooling Fan

The TSUJ Kepler-C72J-OYS-0339 is a 6038 form-factor fan designed for 12 V DC systems. It draws 1.20 A and uses a two-wire connection for simple integration. The unit suits builders who need a compact brute-force airflow solution in tight spaces. It is not suited for systems that require PWM speed control or a three-wire tachometer signal.

Normal Operation Thermals and Noise

Rated at 12 V and 1.20 A, the fan delivers high air volume while maintaining a steady current draw. The two-wire design means speed stays constant whenever power is applied, so acoustic output does not fluctuate with load changes. No separate fan header or controller is required for basic operation. Builders who need variable-speed curves should look elsewhere.

Sustained Load Behaviour

Under continuous duty the motor maintains its rated 1.20 A draw without additional control circuitry. The brute-force blade profile keeps airflow consistent during extended runs rather than peaking only in short bursts. Heat dissipation scales linearly with the fixed voltage supply. Installations that demand thermal throttling or automatic speed reduction will need an external controller.
