Replacement fan for DWPH UPS C1K C2K C3K

This 70 mm case fan is built as a direct replacement for DWPH UPS C1K, C2K and C3K power-supply units. It fits the 70×70×15 mm mounting pattern and uses a three-pin connector for speed monitoring. The non-LED black frame keeps the appearance neutral inside the chassis. Buyers needing a different voltage, connector type or frame depth will need another model.

Thermals noise and power draw

Rated at 12 V and 0.30 A, the fan draws modest power while providing cooling airflow for the UPS power supply. The manufacturer describes it as a mute silent cooler, indicating low acoustic output during normal operation. No LED lighting means no extra light bleed in darkened rooms. The three-wire design allows the host system to read fan speed for basic thermal management.

Behaviour under sustained load

The 7015 form factor and 0.30 A current rating are specified for continuous duty in the target UPS units. Speed reporting via the third wire lets the power supply adjust cooling as load changes over long periods. Because the fan is designed for a specific OEM application, it is not intended for general-purpose case ventilation or high-static-pressure radiator setups.

Questions about this item

How do I install the 70mm 3-pin fan in a DWPH UPS C1K, C2K or C3K power supply?

Remove the power supply cover, unplug the old fan, align the 70mm mounting holes, secure the fan with four screws, and connect the 3-pin header so the tachometer wire reads speed.

What maintenance or replacement will the efs-07c12h fan need over time?

Dust the blades and frame every few months with compressed air; the sleeve bearing cannot be relubricated, so plan to replace the fan when noise or vibration increases.

At what point does the 12V 0.30A fan hit its limit during continuous UPS operation?

The 0.30A current rating is the first constraint — sustained loads that push the supply toward its maximum output will heat the fan beyond its design airflow.
