SKU CH-QEYB-QA3WX

A 140 mm case fan with a 12 V DC 4-pin connector for quiet computer cooling

  • Quiet operation for focused work or gaming
  • 140 mm size moves more air at lower RPM
  • 12 V DC power for standard motherboard headers
  • 4D plug design simplifies installation and cable routing

140 mm 12 V DC case fan

This 140 mm case fan runs on 12 V DC power and uses a 4D plug connection. It is built for PC builders who want a quiet cooling upgrade for standard mounting points. The design targets low noise while moving air through a chassis.

Direct replacement for noisy stock fans

Swapping a loud original cooler for this unit cuts acoustic output without changing the mounting layout. The improvement is worthwhile when the existing fan rattles, whines or simply moves too little air for the current build.

Questions about this item

Will the 140mm frame fit my standard 140mm case mount?

Yes, the fan measures 140mm square, matching the standard 140mm mounting holes found on most PC cases.

How do I connect the 4D plug to my motherboard, and what is the common mistake?

Align the 4-pin connector with the motherboard header tab; the error is forcing it in offset by one row, which bends pins and stops speed control.
