  • Daisy-chain wiring cuts cable count and frees motherboard headers
  • PWM control spans 500 to 2000 RPM for flexible speed curves
  • Hydraulic bearing keeps noise at 25.8 dB-A while delivering 57.05 CFM
  • Anti-vibration mounts on a 25 mm frame reduce chassis resonance

Two-Fan Pack for Case Cooling

This 2-fan pack supplies a pair of 120 mm case fans with hydraulic bearings and PWM control. The black, non-LED units suit builders who want straightforward airflow without lighting. Each fan measures 120 x 120 x 25 mm and connects via a standard 4-pin PWM header.

Daisy-Chain Wiring Under Load

The daisy-chain design lets both fans run from a single motherboard header, reducing cable clutter while maintaining PWM speed control across the 500-2000 RPM range. At full speed the pair delivers 57.05 CFM each at 25.8 dB-A, and the hydraulic bearing is rated for sustained operation.

57.05 CFM Airflow per Fan

The 57.05 CFM rating at 2000 RPM is the key figure for matching these fans to your case’s airflow requirements. If your build needs higher static pressure or greater volume per fan, this specification determines whether the CT120 meets the target.

Questions about this item

How loud are the CT120 fans when they run at full speed all day?

At maximum 2000 RPM the fans produce 25.8 dB-A, a level most people barely hear over typical system noise.

What motherboard header do I need to control both fans in the pack?

Each fan uses a 4-pin PWM connector and the daisy-chain design lets both fans run from a single motherboard header.

Will the 25 mm thick CT120 fans fit in the same 120 mm mounts as my older case fans?

Yes, they share the standard 120 x 120 x 25 mm dimensions, so they drop into any existing 120 mm mounting points.
