Thermaltake TH420 V2 Ultra ARGB Snow CL-W407-PL14SW-A Liquid / Water Cooling

The Thermaltake TH420 V2 Ultra ARGB Snow is a white, 420-class liquid CPU cooler with a copper block, aluminum radiator, and three 140 mm PWM fans, suited to PC builders seeking a large-radiator cooling setup with ARGB lighting.

Recommended For

• Builders cooling a high-end desktop CPU in a case that supports a 420 mm radiator, especially for sustained multithreaded work where added cooling headroom can help maintain CPU boost performance.
• White-build enthusiasts with a spacious case who want a coordinated white 420 mm AIO and ARGB lighting, along with an LCD-equipped pump block for a more display-focused PC build.
• PC builders who want strong cooling with the option to tune fan speeds for quieter everyday workloads, rather than running the fans at maximum speed.

Real-World Use Scenarios

• When running long CPU-heavy renders or other sustained workloads on a mainstream high-end processor, the 420 mm cooler can help keep temperatures in check; a review of this model found upper-tier cooling performance on its test platform.
• For a white showcase PC in a case that supports a 420 mm radiator, the Snow finish, ARGB fans, and customizable pump-screen content let the cooler contribute to the build’s appearance as well as CPU cooling.
• While gaming or monitoring a busy PC, users can set the pump LCD to show system information, so selected readings are visible through the case window without opening a monitoring app.
• When planning a new build or cooler upgrade, check the case’s radiator clearance and mounting position first; this 420 mm unit is intended for medium-to-large cases that explicitly support that radiator size.
