All-in-one liquid cooler for mainstream sockets

The Thermaltake TH420 V2 Ultra ARGB Snow is a closed-loop liquid cooler built around a 456 x 139 x 27 mm aluminum radiator and a copper cold plate. It mounts on Intel LGA 2066, 2011-3, 2011, 1851, 1700, 1200, 1156, 1155, 1151, 1150 and AMD AM5, AM4, AM3+, AM3, AM2+, AM2, FM2, FM1 platforms. The white finish and addressable RGB lighting suit clean, light-themed builds.

White tubing and ARGB fans simplify cable routing

Three 140 x 140 x 25 mm PWM fans are pre-installed on the radiator, each spinning between 500 and 1800 R.P.M and moving 84.32 CFM. Rubber tubes run 460 mm from the block to the radiator, giving enough length for most mid-tower layouts while the white sleeves keep the loop visually consistent. Standard 140 mm fan spacing means the unit drops into any case with triple 140 mm top or front mounts.

PWM curve keeps noise low at idle

At full speed the fans reach 34.7 dB-A, a level that stays unobtrusive in a typical system. The 500 R.P.M floor lets the cooler run near-silent during light loads, while the 1800 R.P.M ceiling provides headroom for sustained CPU workloads. Power draw follows the PWM signal, so the cooler only consumes what the current thermal demand requires.

Questions about this item

What socket standard does the TH420 V2 Ultra ARGB Snow block support and what does that limit in practice?

The copper cold plate fits Intel LGA 1851, 1700, 1200, 1150, 1151, 1155, 1156, 2011, 2011-3, 2066 and AMD AM5, AM4, AM3+, AM3, AM2+, AM2, FM2, FM1, so the cooler is limited to those desktop platforms.

What are the radiator dimensions and how many 140 mm fan slots does the case need?

The aluminum radiator measures 456 x 139 x 27 mm and provides three 140 mm fan slots, so the case must accept a 456 mm long triple-fan radiator.

How is the cooler installed and which step is often done wrong?

Mount the backplate and standoffs for the specific socket, apply paste, seat the pump block, secure the radiator with three 140 mm fans, connect the PWM fan header and the ARGB cable to a 5 V header; the step most often missed is plugging the ARGB lead into the motherboard 5 V addressable header instead of a 12 V RGB header.
