Ventoinha Thermaltake CT140 14 cm branco 500–1500 rpm 2 unid.

The Thermaltake CT140 is a 140 mm PC cooling fan available in white, supplied as a pack of two. It operates across a PWM-controlled speed range of 500–1500 RPM, delivers up to 2.3 mm-H2O static air pressure and an airflow of 77.37 CFM, and measures 140 x 140 x 25 mm. The model features a robust frame and specially tuned seven-blade design to improve airflow and reduce air leakage around chassis or radiator mounts, while integrated anti-vibration pads help reduce noise and vibration.

Advantages

The CT140 combines a tuned blade profile and steady frame construction to provide a balance of airflow and pressure suitable for case and radiator use. A cable-integrated daisy-chain PWM design reduces the number of 4-pin motherboard headers required and shortens inter-fan cable runs. Four non-detachable rubber anti-vibration pads on each corner increase stability and lower transmitted vibration without adding extra parts.

Suitable for

• General case cooling for mid-tower and full-tower PCs
• Radiator cooling for 140 mm-compatible liquid cooling solutions
• Upgrading stock fans to improve airflow and reduce noise

How to use

Install the CT140 fans in your PC case or on a compatible 140 mm radiator using the appropriate mounting screws. Connect the daisy-chained PWM cables between fans and to a single 4-pin PWM header on the motherboard or to a PWM fan controller. Configure fan speed control in your motherboard BIOS or fan-control software to set desired RPM profiles within the 500–1500 RPM range.

Recommendations

For best results, mount the fans so airflow direction matches your case cooling strategy (intake or exhaust) and ensure secure screw mounting to maintain contact with the anti-vibration pads. Use the provided daisy-chain cables to minimize 4-pin header usage and keep cable routing tidy; verify fan operation after initial power-up and adjust PWM curves if necessary to balance cooling and noise.
