Fan Thermaltake Pure Duo 14

Thermaltake Pure Duo 14 is a 140 mm PWM-controlled case fan with a dual LED ring featuring 16.8 million addressable colors and compatibility with 5V RGB-capable motherboards. The fan uses a hydraulic bearing and a nine-blade impeller to deliver balanced airflow and quiet operation, with a rotational speed range of 500–1500 RPM and maximum static pressure of 2.24 mmH2O. It operates from 5 V and 12 V sources and comes in a black finish suitable for most PC builds.

Advantages

The dual 2-ring LED design, with nine addressable LEDs per ring, provides even color distribution and high brightness across the fan. PWM control and a nine-blade profile improve airflow and cooling efficiency while keeping noise levels low. A hydraulic bearing with a sealed cap reduces friction and prolongs service life. In-mold anti-vibration rubber pads minimize vibration transfer to the chassis, and the included preset controller offers seven lighting modes for use without a 5V RGB header. The fan is also compatible with major motherboard RGB software when connected to a 5V addressable header.

Suitable for

• Case cooling in desktop PC builds
• Radiator or intake/exhaust fan positions where 140 mm size is supported
• Systems that require addressable RGB lighting synchronized with motherboard software
• Quiet computing setups that benefit from hydraulic bearing technology

How to use

Install the fan in any 140 mm mounting position in your case, using the supplied screws or vibration-damping mounts. Connect the PWM power cable to a 4-pin fan header on the motherboard to enable speed control. For lighting control, connect the 5V addressable RGB cable to a compatible 5V ARGB header on the motherboard to synchronize with ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light, or ASRock Polychrome. If your motherboard lacks a 5V ARGB header, use the included preset controller to select lighting modes, colors, and speeds.

Recommendations

For optimal cooling and noise balance, configure PWM fan curves in the motherboard BIOS or software, place the fan in airflow-appropriate positions (intake or exhaust), and avoid obstructing the fan intake with cables. When using motherboard RGB synchronization, confirm 5V ARGB header compatibility to prevent signal or voltage mismatch.
