All-in-one liquid cooler Thermaltake TT Toughliquid Ultra 420 Black 500-2000 RPM

The Thermaltake TT Toughliquid Ultra 420 is a 420mm all-in-one liquid cooler designed for next-generation CPUs. It integrates a 2.1-inch rotational LCD display for real-time system information and media playback, and comes with three TOUGHFAN 14 RGB fans with a maximum speed of 2000 RPM. The cooler uses a copper base plate and a high-performance pump for efficient heat transfer and continuous circulation, while low-evaporation tubing reduces coolant loss. The package includes mounting brackets compatible with recent Intel and AMD sockets, including LGA1700 and AM5.

Advantages

The rotational 2.1-inch LCD supports JPG, GIF, PNG, MP4, MOV and AVI files at 480×480 resolution and can display time and local weather. Three included 140mm RGB fans provide adjustable speeds up to 2000 RPM for strong airflow and cooling. A copper base plate combined with a reliable pump improves thermal conductivity and maintains consistent coolant circulation. Low-evaporation tubing minimizes maintenance by reducing the need for refills. TT RGB Plus 2.0 software enables fan speed, lighting control and custom content on the LCD.

Suitable for

• High-performance desktop builds with modern Intel or AMD CPUs (including LGA1700 and AM5)
• Systems that require effective 420mm liquid cooling for overclocking or sustained heavy loads
• PCs where aesthetic customization (rotational LCD and RGB fans) is desired

How to use

Install the radiator and fans into a compatible case mounting location for a 420mm radiator following the included manual. Mount the copper base plate onto the CPU using the supplied brackets for your CPU socket (Intel or AMD), apply thermal paste as instructed, and secure the pump block. Connect the fans and pump to the motherboard headers or provided controller, then install the TT RGB Plus 2.0 software to configure fan curves, lighting effects and upload images or videos to the LCD. Verify pump and fan operation in BIOS or monitoring software before normal use.

Recommendations

For optimal cooling performance, ensure good case airflow, use the latest TT RGB Plus 2.0 software for fan and display configuration, and confirm compatibility with your case dimensions for a 420mm radiator. Regularly inspect tubing and fan operation; the low-evaporation tube reduces but does not eliminate the need for long-term checks.
