The ARCTIC Liquid Freezer III Pro 420 supports multiple current-generation processor sockets including LGA 1851, LGA 1700, AM4, and AM5. This broad compatibility makes it an excellent choice for both Intel and AMD systems, whether you’re running a cutting-edge processor or maintaining a slightly older but still powerful build. The fluid dynamic bearing fans operate quietly while delivering exceptional cooling performance across all supported platforms.
Efficient Design with Quality Materials
Built with an aluminum radiator and copper base plate, this cooling kit combines durability with excellent thermal conductivity. The 45 cm tube length provides flexible installation options, while the 6 mm inner diameter ensures efficient coolant flow. The black finish complements most build aesthetics, and the compact pump dimensions (9.1 x 10.8 x 6.85 cm) make it suitable for various case configurations without sacrificing cooling capacity.
