D-Link DEP36W 36W Fan Speed Controller

The D-Link DEP36W is a 12V adjustable power adapter rated at 36W with a maximum 3A output. It connects to AC mains and provides a variable DC voltage for controlling the speed, airflow and noise level of 12V cooling fans or water pumps in PCs, NAS units, AV cabinets or similar enclosures.

Check your fan connectors and power needs

Verify that your fans or pumps use 2-pin, 3-pin or 4-pin headers and draw no more than the adapter's 36W capacity. The included 35cm splitter cable ends in dual 4-pin plugs fed from a DC 5.5×2.5mm jack, so ensure your devices accept this connection type and that the total load stays within the 3A limit.

Suits DIY cooling projects needing variable 12V

This unit fits builders who want manual knob control over multiple 12V fans or a pump in a server, cabinet or water-cooling loop. It is not for users who require PWM signalling from a motherboard header, software-based fan curves, or power delivery above 36W for larger arrays.

Questions about this item

Does the DEP36W ship with the 4×4-pin splitter cable or must I buy it separately?

The package includes the 35 cm DC5521 female to dual 4-pin splitter cable so you can power up to four fans from one adapter.

Which output setting should I select for a typical 12 V case fan?

Turn the adjustable knob to the 12 V position; the adapter delivers up to 3 A and 36 W at that voltage.

What does the 36 W rating mean when the controller is running four fans in a NAS enclosure?

It is the total power budget shared across all connected fans; the combined draw must stay at or below 36 W.
