A powerful and silent watercooling kit With the Liquid Freezer II 420 ARGB all-in-one CPU water cooling kit, ARCTIC puts all its know-how at the service of gaming thanks to a compact PWM controlled cooling pump. Thanks to this system, it does not operate at full load all the time but adjusts its operation to the temperature of the processor to limit its noise level at rest. The set is completed by three 140mm ARGB fans with high static pressure and another 40mm fan near the pump in charge of cooling the motherboard VRM circuits. Benefit from Arctic expertise Thanks to its ingenious design, the this watercooling system does not operate at 100% permanently. Indeed, the PWM system with which it is equipped adjusts its speed according to the demand of the moment. In this way, it is extremely silent at rest while consuming less energy! The Liquid Freezer II also features three ARGB ARCTIC P-series 140 mm hydrodynamic bearing fans with blades designed for better efficiency. Enjoy a reduced level of vibrations, and an extreme lifespan for your new watercooling system. In addition to the standard high static pressure fan, a smaller 40mm fan sits near the pump and takes care of cooling the VRM circuitry on the motherboard so as to prevent overheating in the event of long-term stresses. The water circuit is completely hermetic, so there is no need to add additives.

Great cooler for smaller boxes. Got a revision 4 which has a better mounting system and makes the cooling 2-3 degrees cooler than rev 2.

First unit was DOA leaking but replacement unit (issue resolved rapidly by Scorptec's great team) performs amazingly on even a 7950X, plenty of overclocking headroom and remains insanely quiet.

Quiet, effective and looks good. Currently fitted to a black/white themed pc. If the white led setting was more white that's be great but it's against the black radiator so that's unfair.
not had time to put in yet. looking forward to doing it soon. upgrade CPU need to upgrade cooling
great cooler fantastic price the 420mm performs great not as noisey as old cooler will only fit in top mount of lian li lancool 3
great cooling capacity used on my 17 12700k which runs 24/7
