Cooler Master Hyper 620S ARGB 120mm Dual Tower CPU Air Cooler

The Cooler Master Hyper 620S ARGB (model RR-D6NA-17PA-R1) is a dual-tower CPU air cooler designed for builders who want effective thermal management without switching to liquid cooling. Its dual-tower heatsink configuration doubles the fin surface area compared to a single-tower design, allowing heat to dissipate across a larger area and reducing thermal resistance under sustained workloads. At the heart of the cooler sits a nickel-plated copper base connected to six heat pipes arranged to ensure even contact across the CPU integrated heat spreader. The heat pipes draw thermal energy from the base and route it up into the aluminium fin stacks of both towers, where two included 120 mm fans push air through to exhaust heat. Each fan spins between 650 and 1,750 RPM via a 4-pin PWM connector, letting the motherboard regulate speed automatically based on CPU temperature. At maximum speed the fans move up to 71.93 CFM of air against a static pressure of 1.86 mmH2O, while remaining at or below 27.2 dB(A)—audible under load but unobtrusive during lighter tasks. Rifle-bearing construction underpins a rated MTTF of more than 160,000 hours. Both fans ship with ARGB lighting addressable through any 3-pin ARGB header. If no header is connected, the cooler defaults to an automatic ARGB spectrum cycle on power-up, so the system always looks active without requiring software configuration. The overall heatsink footprint measures 125 × 137 × 154.9 mm. The 154.9 mm height is intentionally kept low to fit the majority of mid-tower and full-tower cases without requiring RAM clearance compromises. Socket compatibility spans Intel LGA 1700, 1200, 1156, 1155, 1151, 1150 and AMD AM5 and AM4, covering a wide range of current and recent-generation platforms including Intel Core 12th through 14th Gen and AMD Ryzen 5000 and 7000 series processors.
