Thermaltake TH420 V2 ARGB liquid cooler CL-W376-PL14SW-A

420 mm radiator AIO for Intel and AMD CPUs

The Thermaltake TH420 V2 ARGB is a 420 mm all-in-one liquid cooler built for current Intel LGA 1700 and AMD AM5 platforms as well as older sockets. A copper cold plate transfers heat to an aluminium radiator measuring 456 x 139 x 27 mm. Three 140 mm fans with hydraulic bearings push up to 84.32 CFM through the fins. Addressable RGB lighting on the pump and fans syncs via a 5 V three-pin header.

Socket coverage decides fit

Block compatibility lists Intel LGA 2066, 2011, 1851, 1700, 1200, 1156, 1155, 1151 and 1150 plus AMD AM5, AM4, AM3+, AM3, AM2+ and AM2. If your motherboard uses a socket outside this list the cooler will not mount. The pump connects with a standard 4-pin PWM header (2510 type) and a separate 5 V ARGB header for lighting control.

Thermals and acoustics at load

At maximum PWM speed of 1800 RPM the fans produce 34.7 dB-A while moving 84.32 CFM across the radiator. The hydraulic bearing design keeps noise steady through the 500 to 1800 RPM range. Rubber tubes 460 mm long give enough reach for most mid-tower and full-tower layouts without kinking. Power draw is limited to the fan and pump headers on the motherboard.
