Refrigeração líquida all-in-one Thermaltake TH420 ARGB Sync

The Thermaltake TH420 ARGB Sync is a 420mm all-in-one liquid cooler designed for next-generation CPUs. It includes a copper base plate, a reliable pump for continuous water circulation and low-evaporation tubing to minimise coolant loss. The cooler comes in black and supports 5V addressable RGB motherboard synchronization for unified lighting control.

Advantages

The TH420 ARGB Sync combines a large 420mm radiator with three performance-tuned 140mm ARGB fans capable of up to 1800 RPM, delivering improved airflow and static pressure in the affordable AIO segment. The copper base plate and efficient pump speed up heat transfer and maintain stable temperatures while the low-evaporation tube reduces maintenance by minimising coolant loss. Integrated ARGB with 9 addressable LEDs per fan and 5V motherboard support allows direct lighting control through compatible motherboard software.

Suitable for

• Cooling high-performance or next-generation desktop CPUs
• PC builds requiring a 420mm AIO radiator
• Systems where synchronized 5V ARGB lighting is desired

How to use

Install the TH420 ARGB Sync radiator and fans into a compatible chassis that supports a 420mm radiator, following the included mounting instructions. Mount the pump/block assembly onto the CPU socket using the supplied brackets and fasteners, connect the pump power and fan headers to the motherboard, and attach the 5V addressable RGB cable to a compatible 5V ARGB header for lighting control. Power the system and configure fan curves and lighting through the motherboard software.

Recommendations

Use a chassis confirmed to support a 420mm radiator (for example Thermaltake Ceres 500 Mid-Tower) and a motherboard with a 5V ARGB header. Ensure proper airflow direction for radiator fans and configure fan curves in BIOS or motherboard software to balance noise and cooling performance. Note that ARGB lighting requires motherboard sync support.
