120mm Thermaltake TS140 EX RGB 3-pack case fans, PWM, black

The Thermaltake TS140 EX RGB 3-pack contains three 120 mm case fans engineered to provide adjustable cooling and address airflow needs in desktop PC cases and radiators. Each fan integrates RGB lighting and PWM speed control, allowing users to balance acoustic levels and thermal performance. The fans are finished in black and are intended for installations where compact 120 mm fans are required for intake, exhaust, or radiator configurations.

Advantages

The fans offer PWM control for automatic speed regulation based on motherboard or fan controller signals, which helps maintain lower noise at light loads and higher airflow under heavy loads. Integrated RGB lighting enables visual customization compatible with common motherboard lighting headers and controllers. The 120 mm form factor fits a wide range of cases and radiator mounts, and the multi-pack provides a matched set for consistent airflow characteristics across multiple mounting positions.

Suitable for

• Standard desktop towers requiring additional intake or exhaust fans
• Gaming PCs where adjustable cooling and RGB lighting are desired
• Compact workstations and home office systems with 120 mm mounting points
• Radiator setups that accept 120 mm fans for liquid cooling

Key specifications

• Fan size: 120 mm diameter
• Control: PWM (pulse-width modulation) for automatic speed adjustment
• Lighting: Addressable RGB illumination integrated into each fan
• Color / finish: Black frame and blades
• Pack quantity: Three identical fans supplied together

How to use

Install the fans into compatible 120 mm mounts in your computer case or to a radiator using the supplied screws or standard fan screws. Connect the PWM power connector to a motherboard fan header or PWM-capable fan controller to enable automatic speed control. Connect the RGB lighting cable to a compatible addressable RGB header or controller to manage lighting effects and synchronization. Verify airflow direction markings on the fan frame when positioning for intake or exhaust to achieve the intended airflow pattern.

Recommendations

For balanced cooling and noise, configure one or two fans as intake and the remainder as exhaust to establish a slight positive or neutral case pressure. Use motherboard fan curves to set RPM thresholds tied to CPU or system temperatures. When mounting on radiators, ensure sufficient clearance between fan blades and radiator fins and confirm that the RGB header and PWM header types match the motherboard/controller specifications before connection.
