  • Product colorWhite
  • Modular interlocking connects up to 6 fans per controller port
  • 18 cm extension cable enables 3+3 daisy-chained clusters

  • 28 mm frame delivers 10 % airflow gain over 120 mm V1 model

140mm White Modular Case Fan

This 140mm white case fan uses a revised interlocking design that lets up to six fans connect to a single controller port. A plug-in cable module sits flush with the 28mm frame to reduce clearance issues. An 18cm extension cable enables a 3+3 daisy-chained cluster for simpler cable routing.

Builders Who Want Daisy-Chained RGB Cooling

The removable interlocking keys improve compatibility with radiator fittings, suiting liquid-cooled builds that need tight clearances. It is not for systems that lack a compatible UNI HUB controller or builders who prefer standalone fans without proprietary connectors.

Airflow Optimised for Dense Radiators

The 28mm thick frame delivers a 10% airflow gain over the previous 120mm design, balancing static pressure and volume for restrictive radiators. Headroom exists for high-FPI stacks, but the single-fan pack requires additional units to reach the six-fan cluster limit.

Questions about this item

Do I need a UNI HUB controller to run the 140mm White Case Fan?

Yes, the fan connects through the plug-in cable module to a UNI HUB controller, which supplies power and manages up to six fans across two clusters.

Can I daisy-chain this 140mm fan with older SL120 V1 fans using the interlocking keys?

The V2 interlocking style is revised; removable keys improve radiator clearance but the new 18 cm extension cable is designed for V2-to-V2 clusters, so mixed V1/V2 daisy-chaining is not supported.

How can I confirm the 140mm fan is delivering the 10% airflow gain after installation?

Monitor RPM and temperature drop in your fan-control software; the 28 mm thick frame should produce measurably higher static pressure at the same speed compared with the previous 120 mm V1 design.
