Hybrid cooler Thermaltake TH420 V2 Ultra ARGB 84.32 cfm 3.02 mmH2O White

The TH420 V2 Ultra ARGB Snow is a 420mm AIO liquid CPU cooler with a 2.1" 480 x 480 resolution LCD display and three CT140 ARGB White fans. Designed for medium to large chassis that support 420mm radiators, this Ultra series model offers a slim 27mm radiator with a 20mm-thickened copper chamber, an integrated daisy-chain cable design for simplified wiring, and broad CPU socket compatibility including Intel LGA1700 and AMD AM5.

Advantages

The high-resolution 2.1" LCD display supports 16.8M color images and videos (JPG, GIF, PNG, MP4, MOV, AVI) and can show real-time information such as temperature and local time. The slim radiator and larger copper chamber improve thermal transfer while keeping installation straightforward. The included cable-integrated daisy-chain reduces the number of motherboard PWM and 5V ARGB headers required and shortens inter-fan cable runs. A secure 5V ARGB connector clip prevents accidental disconnection. The copper base plate and reliable pump maximize heat conductivity and coolant circulation, and the low-evaporation tube minimizes coolant loss.

How to use

Mount the radiator and fans into a chassis that supports 420 mm AIOs following standard cooler installation procedures and the included mounting brackets for Intel and AMD sockets. Connect the integrated daisy-chain fan cable to the motherboard PWM header and the ARGB cable to a 5V addressable RGB header or to the included controller as needed. Upload images or videos to the 2.1" LCD using the supported file formats to customize startup or standby screens, or use TT RGB PLUS 2.0 software to configure lighting, monitor temperatures, and set display content. Ensure the 5V ARGB connector clip is engaged to prevent disconnection during assembly or transport.

Recommendations

For reliable operation and full feature access, install TT RGB PLUS 2.0, ensure your motherboard has a 5V addressable RGB header for lighting sync if required, and verify chassis clearance for a 420 mm radiator. Use the included brackets for correct CPU socket mounting and secure the ARGB connector clip to avoid loose connections.
