PC-ventilator THERMALTAKE CT140 Reverse ARGB Sync 140mm Hydrangea Blue 2-pack

Thermaltake CT140 Reverse ARGB Sync 140mm Hydrangea Blue (pack of 2) are high-performance cooling fans designed for case and radiator applications in desktop PCs. Each fan uses a reverse-blade design to improve airflow pressure and control while offering addressable RGB lighting that synchronizes with compatible motherboards and controllers. The Hydrangea Blue color provides a coordinated aesthetic for builds that require subtle, cool-toned lighting and fan frames. Sold as a pair, these 140mm fans are suitable for systems where a balance of airflow, static pressure and visual customization is required.

Advantages

The reverse-blade geometry increases airflow efficiency and static pressure for improved heat dissipation around radiators or tightly packed case interiors. Addressable RGB lighting enables per-LED effects and synchronization with many motherboard RGB ecosystems, allowing precise control over colors and patterns. The 140mm size delivers strong airflow at lower rotational speeds compared with smaller fans, reducing audible noise while maintaining cooling performance. Packaged as two fans, the set facilitates multi-fan installations for consistent airflow distribution.

Suitable for

• Case cooling in mid-tower and full-tower desktop systems
• Radiator cooling for liquid-cooling loops (140mm radiator compatibility)
• Upgrading airflow and aesthetics in gaming PCs and workstations
• Multi-fan configurations requiring synchronized ARGB lighting

Key specifications

• Fan size: 140 mm diameter
• Blade design: reverse-blade for enhanced static pressure
• Lighting: addressable RGB (per-LED control, sync-capable)
• Frame color: Hydrangea Blue
• Pack quantity: 2 fans
• Application: case and radiator cooling

How to use

Install each fan into appropriate 140mm mounting locations in the case or onto a compatible 140mm radiator using the supplied screws or standard fan mounting hardware. Connect the power and lighting connectors to the system: use the fan power header compatible with your controller or motherboard and attach the ARGB connector to an addressable RGB header or ARGB controller for lighting control. Orient the fans to achieve the desired airflow direction—intake or exhaust—according to your case layout and thermal requirements. Verify secure mounting and cable routing to prevent interference with other components and to maintain unobstructed airflow.

Recommendations

For optimal cooling performance, combine these 140mm reverse-blade fans with proper case airflow planning—intake at the front/bottom and exhaust at the top/rear. Use a motherboard or dedicated ARGB controller that supports addressable RGB to unlock full lighting control and synchronization. Periodically inspect and clean fan blades and filters to maintain airflow and prevent dust buildup that can reduce cooling efficiency.
