3-Pin Fan Extension Cable Set

The NA-SEC2 supplies three 30cm black extension cables with 3-pin male-to-female connectors. They are designed for PC builders who need extra reach when routing fans inside larger cases. The fully sleeved cables suit Noctua 3-pin fans at 24V, 12V and 5V as well as many third-party 3-pin models. This set does not serve builders who require 4-pin PWM connectors.

30cm Reach and Daisy-Chain Headroom

Each cable adds 30cm of length, and the three can be daisy-chained for a combined 90cm run when a single cable falls short. The UL 94 V-0 rated sleeving resists mechanical wear, heat and flames for reliable operation in demanding environments. Installations needing more than 90cm total extension will require additional cables beyond this pack.

3-Pin Connector Compatibility

The sole specification that decides fit is the 3-pin male-to-female connector pair on every cable. It matches all Noctua 3-pin fans across 24V, 12V and 5V variants plus numerous third-party 3-pin fans. Any fan or header using a 4-pin PWM interface will not connect with these cables.

Questions about this item

Will these 30cm 3-pin extensions reach from a bottom-mounted motherboard header to a top-mounted fan in a full-tower case?

Each cable is 30cm long; three cables can be daisy-chained for a combined 90cm reach, which covers most full-tower vertical runs.

How can I confirm the 3-pin connection is delivering the correct 12V or 5V signal to my fan after installation?

The fan should spin at its rated speed and report RPM in BIOS or monitoring software; a steady RPM reading confirms the 3-pin signal and power lines are intact.

Does the 3-pack include any 4-pin adapters or PWM splitters, or just the three 30cm black-sleeved male-to-female cables?

The set contains only three 30cm NA-EC2 extension cables with 3-pin male-to-female connectors and black sleeving; no adapters or splitters are included.
