Thermaltake CT120 EX ARGB PC Cooling Fan Hydrangea Blue - Quiet

Our review of the Thermaltake CT120 EX ARGB Sync (3-Fan Pack) finds it best for PC builders who want strong airflow and showpiece lighting without complex cabling. The single biggest reason to buy is the new MagForce 2.0 magnetic connection, which makes daisy-chaining three 120 mm fans fast and tidier than traditional connectors, while the 9-addressable LED layout delivers uniform color across the fan face. These fans aim to balance performance, low noise, and easy installation for desktop and radiator use.

Key Features

• MagForce 2.0: Larger pogo pin contact pads reduce alignment issues and let multiple fans connect with a single cable for cleaner builds and faster setup.
• ARGB Lighting: Nine addressable LEDs per fan provide even coverage and support 16.8 million colors via 5V motherboard sync software for coordinated effects.
• Performance: PWM control and a top speed of 2000 RPM produce up to 68 CFM of airflow and 2.95 mm-H2O static pressure suitable for case ventilation and thin radiators.
• Low Noise: An optimized hydraulic bearing keeps operation quiet at about 28.5 dBA, so lighting and cooling are noticeable without being distracting.
• Magnetic Cable Routing: Magnetic daisy-chaining and shorter external cabling reduce wire clutter behind the motherboard tray for neater wire management.

Who It's For

The CT120 EX ARGB pack is ideal for PC enthusiasts building a midrange gaming or workstation PC who want strong airflow and showy synchronized lighting. It suits systems where neat cable routing matters and where users will run the fans through a 5V motherboard ARGB header to control effects.

Users who prioritize absolute top-end static pressure for thick radiators or who lack a compatible 5V ARGB header may want to consider different fans or an ARGB controller, since the lighting and daisy-chain features assume motherboard sync support.

Pros & Cons

Pros

• Quiet operation and reliable hydraulic bearing design make these fans pleasant for daily use.
• MagForce 2.0 magnetic connectors simplify multi-fan setups and reduce cable clutter.
• Strong, even ARGB lighting with 9 LEDs per fan produces vivid, uniform colors when synced.
• Good airflow and static pressure figures for 120 mm fans at up to 2000 RPM.

Cons

• Price is a common concern for some buyers who find the pack a bit costly compared with basic case fans.
• ARGB requires a 5V motherboard header or third-party controller to access full lighting control.
