• The TH420 V2 ARGB Snow Edition features a 420mm radiator with a trio of 140mm ARGB fans, delivering exceptional thermal performance for high-TDP processors. With a larger radiator surface area and precisely tuned fan blades, this kit maintains lower CPU temperatures even during lengthy gaming sessions or demanding rendering tasks, enabling you to push your hardware further without ramping up noise. The white Snow Edition aesthetic adds a premium, cohesive look to cases with white interiors or webbed LED layouts, making it a visually striking centerpiece for your build.
• Vibrant ARGB lighting and synchronized control give your rig a dynamic, immersive glow. Each fan and the pump are equipped with addressable RGB elements that can be coordinated with most motherboard RGB headers or Thermaltake’s own lighting controller. The Snow Edition’s lighting is designed to be bright, evenly distributed, and highly customizable, allowing you to choose from millions of colors and a wide range of effects—from breathing modes to ripple and music-synced patterns—without compromising performance.
• Effortless compatibility and installation are at the core of the TH420 V2 Snow Edition. It supports a broad range of Intel and AMD sockets, and Thermaltake’s mounting hardware is designed for straightforward, tool-free installation in most mid- to full-tower cases that can accommodate a 420mm radiator. The all-in-one design reduces the complexity of custom loop builds while still delivering top-tier cooling efficiency, making it an excellent upgrade path for gamers, content creators, and PC enthusiasts looking to maximize thermal headroom with minimal hassle.
• Durability and reliability are integral to Thermaltake’s AIO design. High-quality tubing is paired with a robust pump, engineered to withstand continuous heavy use while maintaining peak performance. The Snow Edition’s white casing not only looks sleek but also helps resist discoloration and showing signs of aging under bright LED exposure. This cooler is built to last, offering dependable cooling across many seasons of intense computing workloads while keeping maintenance minimal and straightforward.
• Quiet operation complements its formidable cooling. The three 140mm fans are designed to balance airflow with low noise levels, and the pump is engineered for smooth, stable operation. When paired with properly ventilated cases and clean cable management, the TH420 V2 ARGB Snow Edition achieves a refined acoustic profile, ensuring your system remains comfortable to use even during long gaming sessions, streaming marathons, or rendering tasks where thermal throttling could otherwise occur.

How to install Thermaltake TH420 V2 ARGB Snow Edition

Preparing your system for installation begins with a quick assessment of your case clearance. Ensure your chassis can accommodate a 420mm radiator and that there is a clear path for routing tubing and cables. If your case includes a dedicated mounting area for large radiators, ensure you have the required standoffs and screws for secure attachment. Gather your motherboard and power connectors so you can plan the wiring without obstructing fans or cables. The installation process is designed to be user-friendly, and the all-in-one design minimizes the number of separate components you must assemble.

Step 1: Install the radiator and fans. Attach the three 140mm ARGB fans to the 420mm radiator using the supplied screws, aligning them for optimal airflow direction toward the case exhaust. Place the radiator with the fans mounted into your case’s radiator location, using the appropriate mounting holes and spacers. Step 2: Mount the pump/block assembly. Position the CPU block on the socket, applying a thin, even layer of thermal paste if the paste pre-applied to the block requires adjustment. Secure the block with the supplied mounting hardware for your socket type, ensuring even pressure across the heat spreader. Step 3: Route tubing and connect. Gently route the tubing from the pump to the radiator, avoiding sharp bends. Connect power and ARGB cables to your motherboard headers or Thermaltake controller as per your design preference. Step 4: Connect power and lighting. Plug the 4-pin PWM fan header into your motherboard or a dedicated controller for synchronized performance. Attach the 3-pin or 5V ARGB header as required to enable the full range of lighting effects, then connect the pump’s power to the appropriate header. Step 5: Power up and test. Boot your system and check that all fans spin correctly, lighting is displaying as configured, and the coolant pump operates smoothly without unusual noises. Step 6: Tidy cables and finalize. Use zip ties to secure cables away from fans and airflow paths, ensuring a clean look inside the case and unobstructed air circulation. Finally, run a brief stress test to verify cooling performance under load and adjust fan curves for the balance you prefer between temperatures and acoustics.
