  • Cable Length1 ft.
  • Extends PWM fan reach with 30 cm length
  • Jet Black sleeving creates a clean, uniform look

  • 12 inch cable suits compact or full-size builds

PWM fan extension for tidy builds

This 30 cm PWM fan extension cable adds reach between a motherboard header and a case or CPU fan without rewiring the loom. The jet-black sleeving keeps the single cable visually clean inside windowed chassis. It suits builders who want a short, neat link rather than coiling excess length.

Keyed four-pin plug prevents misalignment

The moulded 4-pin connectors are keyed so they seat in one orientation only; forcing them the wrong way bends pins on the header. Route the cable before seating both ends to avoid stress on the latch tabs. No tools are required beyond fingertip pressure.

30 cm reach suits CPU and rear-exhaust fans

The 12 inch length comfortably spans from a top-mounted motherboard header to a rear or top-case fan position. It will not reach front-intake fans in full-tower layouts or dual-radiator loops that demand longer runs. Buyers needing more length should select a longer variant.

Questions about this item

How do I confirm the 4-pin PWM signal is passing through the 30 cm extension after I connect it?

The fan should spin and respond to speed curves in BIOS or fan-control software, proving the PWM wire is active across the 30 cm length.

Does the Jet Black sleeved cable include both the male and female 4-pin connectors, or must I buy a connector separately?

The 30 cm extension ships with a male plug on one end and a female socket on the other, so no extra connectors are required.

Should I choose the 30 cm version or a longer cable for a mid-tower build?

At 30 cm the DS-0521 reaches from a motherboard header to a nearby fan; select a longer cable only if the routing distance exceeds 30 cm.
