## Long description

The Thermaltake TH420 V2 ARGB Snow liquid cooling kit combines a slim 420mm radiator, an industrial-style infinity mirror cap and three CT140 ARGB White fans to deliver low-profile, addressable-RGB cooling for large PC cases. The kit includes a copper base plate, a high-performance pump, pre-mounted ARGB fans with a daisy-chain cable design, and mounting brackets compatible with current Intel and AMD sockets.
Advantages
The TH420 V2 ARGB Snow offers improved cooling in a compact 27mm radiator with a 20mm thickened copper chamber and a high-performance copper base plate to speed heat transfer. Integrated fan daisy-chain cabling reduces the number of motherboard headers required and shortens inter-fan cable runs, while a 5V ARGB connector clip secures lighting cables. The package supports motherboard RGB synchronization via 5V addressable headers and includes necessary PWM and ARGB cables for straightforward installation.
Suitable for
High-performance desktop builds with support for 420mm AIO radiators
PC systems that require motherboard-controlled 5V ARGB lighting (ASUS Aura, GIGABYTE RGB Fusion, MSI Mystic Light, ASRock Polychrome)
Users who prefer a white-themed or snow-style chassis aesthetic

How to use
Install the radiator into a compatible chassis location for 420mm AIOs and mount the three CT140 fans onto the radiator according to airflow direction. Attach the pump cold plate to the CPU using the included brackets and fasteners for your specific Intel or AMD socket. Connect the fan PWM cable and the 3-pin 5V ARGB cable to the corresponding headers on the motherboard, and use the integrated daisy-chain fan wiring to link fans together. Secure the 5V ARGB cable with the supplied connector clip to prevent accidental disconnection.
Usage recommendations
For reliable lighting control, connect the ARGB cable to a 5V addressable RGB header and use the motherboard vendor’s RGB software (ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light, or ASRock Polychrome). Ensure your case supports a 420mm radiator and provide adequate case airflow for optimal cooling performance.
