Arctic ACFRE00181A Liquid Freezer III Pro 420 AIO Cooler — 3 x 140mm, Intel LGA1851/1770 & AMD AM5/AM4, Black

All-in-one water cooler with a 420mm radiator and three 140mm P14 PRO fans. Includes a contact frame compatible with Intel LGA1851 and LGA1700 that evens out contact pressure to improve heat dissipation and extend CPU lifespan.

ARCTIC P14 PRO fans deliver greater cooling capacity and lower noise than the standard P14, offering especially quiet operation at low RPMs and a higher top speed for demanding loads. The cold plate is mounted with an offset native to both Intel and AMD sockets, positioning the cooling contact toward the CPU hotspot for more effective heat transfer.

Built-in PWM-controlled VRM fan reduces voltage-regulator temperatures to help maintain stable performance. Cable management is integrated into the hose sleeving so the radiator fans’ PWM leads are routed internally and only a single cable needs to be connected to the motherboard.
