SKU CH-25A9-6MX3J

Red 29 cm cable connects a DC 5521 power supply to a large 4-pin fan with an inline on/off switch

  • Powers 4-pin fans from common DC adapters
  • Built-in on/off switch for instant fan control
  • Pure copper 22 AWG conductors rated 300 V 80 °C
  • Flexible 29 cm red PVC jacket OD 3.5 mm
  • Light 20 g cable connects 5521 plug to large 4-pin

Cable purpose and fit

This adapter cable connects a DC 5521 power source to a large 4-pin chassis fan. It is intended for builders who want to run a 4-pin fan from an external 12 V, 9 V or 5 V supply such as a router or camera adapter. The 29 cm red cable includes an inline on/off toggle switch for manual control.

Setup check before ordering

Verify that your fan uses a large 4-pin power connector and that your power supply provides a DC 5521 plug at 12 V, 9 V or 5 V. The cable is wired with 22 AWG conductors (17 × 0.10 mm pure copper) rated to 300 V and 80 °C, so ensure the supply voltage and current stay within those limits.

Thermals noise and power

The PVC-insulated 3.5 mm diameter cable weighs 20 g and adds negligible resistance to the fan circuit. No active cooling or fan is present on the adapter itself, so it produces no audible noise. Power draw depends entirely on the connected fan and the chosen supply voltage.

Questions about this item

What connectors come on the cable and do I need any extra adapters?

The cable has a large 4‑pin connector on one end and a DC 5521 jack on the other; no extra adapters are required to link a 12 V, 9 V or 5 V power supply to a 4‑pin chassis fan.

Which length or wire gauge should I pick for my build?

This single version is 29 cm long, uses 2468 22 AWG wire with 17 × 0.10 mm pure‑copper conductors and a 3.5 mm outer diameter, rated for 300 V at 80 °C.

Will the 300 V rating handle a typical 12 V fan safely?

Yes — the 300 V rating far exceeds the 12 V, 9 V or 5 V supplies used for chassis fans, so the cable operates well within its voltage limit.
