Model CT140

  • Quieter cooling with 30.5 dB-A hydraulic bearing
  • Strong airflow delivering 77.37 CFM at 1500 RPM
  • Daisy-chain wiring cuts cable clutter for two fans
  • Anti-vibration mounts reduce resonance in 140 mm frame
  • PWM control scales speed from 500 to 1500 RPM

Thermaltake CT140 2-Fan Pack 140mm Hydraulic

This two-fan pack fits standard 140 mm case mounts and connects through a single 4-pin PWM header. The daisy-chain design lets both fans share one motherboard port, reducing cable clutter inside the chassis. It is aimed at builders who want coordinated airflow without occupying multiple fan headers.

Daisy-chain wiring and hydraulic bearing

Each unit uses a hydraulic bearing rated for quiet, long-life operation at speeds between 500 and 1500 RPM. The seven-blade profile is shaped to balance airflow and static pressure for radiator or case use. Anti-vibration pads on the corners limit mechanical noise transmitted to the frame.

77.37 CFM at 30.5 dB-A

At maximum speed the pair moves 77.37 CFM while producing 30.5 dB-A, a level suited to noise-sensitive builds. Buyers who need higher static pressure for dense radiators or who require addressable RGB lighting should look elsewhere. The non-LED black finish keeps the appearance neutral for windowed or closed cases.

Questions about this item

When will the hydraulic bearings in the CT140 fans need replacement?

Hydraulic bearings are sealed for the life of the fan; no scheduled replacement interval is required under normal operation.

What limits sustained airflow when the CT140 runs at full speed for hours?

The 1500 RPM ceiling caps airflow at 77.37 CFM per fan, so the motor speed limit is reached before any thermal throttle.

How much noise and heat do the two CT140 fans add when running all day at maximum PWM?

At 1500 RPM each fan emits 30.5 dB-A; two fans together stay near that level, and the hydraulic bearing keeps motor heat low.
