Thermaltake TH420 V2 Ultra ARGB Liquid Cooler - High-Resolution LCD

In this review the Thermaltake TH420 V2 Ultra ARGB stands out as an option for builders who want a large 420mm AIO with a prominent display and motherboard-synced lighting. The single biggest reason to consider it is the 2.1' LCD with a 480x480 panel that displays 16.8M colors and can play images or short video files, which elevates case aesthetics while the thickened copper chamber and copper base plate handle heat transfer reliably. Installation is straightforward for compatible sockets and the included ARGB fans sync with popular motherboard software.

Key Features

• 2.1' 480x480 LCD: Lets you show photos, GIFs, or small MP4 clips and real-time info to personalize your build and monitor at a glance.
• Wide socket compatibility: Supports modern Intel and AMD sockets including LGA 1700 and AM5 so it fits most current mainstream and enthusiast CPUs.
• Copper base and chamber: A copper base plate with a 20mm copper chamber improves heat conductivity for sustained cooling under load.
• Triple 140mm ARGB fans: Three CT140 ARGB fans with PWM control deliver balanced airflow across the 27mm slim radiator for large chassis that accept 420mm AIOs.
• ARGB motherboard sync: Designed to synchronize with ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync, and ASRock Polychrome for unified lighting control.

Who It's For

The TH420 V2 Ultra ARGB is aimed at PC enthusiasts and content creators who value case presentation as much as thermal performance, and who have a chassis that accommodates a 420mm radiator. Builders who want visual customization will appreciate the high-resolution LCD and motherboard RGB sync.

Those with small cases, single-fan mounting limitations, or who prioritize the absolute quietest pump and fan package at minimal size should look at smaller AIOs instead. Also, users expecting in-depth software integration beyond TT RGB Plus 2.0 may face a learning curve for advanced display content.
