420 mm ARGB liquid cooler for modern Intel

The Thermaltake TH420 V2 ARGB Snow is a closed-loop liquid cooler built around a 456 x 139 x 27 mm aluminium radiator and three 140 mm hydraulic-bearing fans. Its copper cold plate mounts to Intel LGA 2066, 2011, 1851, 1700, 1200, 1156, 1155, 1151 and 1150 as well as AMD AM5, AM4, AM3+, AM3, AM2+ and AM2. White tubing and addressable RGB lighting suit white-themed builds.

Thermals, noise and power draw in normal use

Three 140 mm fans spin between 500 and 1800 RPM via PWM, moving up to 84.32 CFM each while peaking at 34.7 dB-A. The hydraulic bearings keep low-speed operation quiet, and the 4-pin PWM connectors let the motherboard balance airflow against temperature automatically. Rubber tubes 460 mm long give enough reach for most mid-tower layouts without kinking.

White finish and ARGB sync simplify build aesthetics

The all-white radiator, fans and tubing create a consistent look without extra paint or sleeving. A 5 V 3-pin ARGB header connects to compatible motherboards so lighting can be synchronised with other components through standard software. No separate controller or proprietary hub is required, reducing cable clutter inside the case.

Preguntas sobre este artículo

How do I mount the TH420 V2 ARGB Snow on an AMD AM5 socket, and which step is most often missed?

Attach the AMD retention bracket to the copper cold plate first, then secure the four spring-loaded screws in a cross pattern; the step most often missed is plugging the 2510 4-pin PWM and 5V ARGB 3-pin connectors into the motherboard headers before tightening the block.

What maintenance will the 460 mm rubber tubes and hydraulic-bearing fans need after a year of use?

Check the rubber tubes for seepage at the barbed fittings and wipe dust from the 140 mm fan blades; hydraulic bearings are sealed, so no lubrication is required, but plan to replace the coolant every two to three years to prevent algae buildup.

At what point does the 34.7 dB-A noise ceiling limit sustained cooling on this 420 mm radiator?

The fans hit 34.7 dB-A at their maximum 1800 RPM, so once the coolant temperature pushes the PWM curve to 1800 RPM the noise stops rising but heat dissipation plateaus at the 84.32 CFM airflow limit.
