The Arctic Freezer A35 A-RGB is easy to install with spring-loaded screws that ensure optimal contact pressure and even distribution of the thermal paste. It is compatible with most AMD AM4 socket processors, including Ryzen series CPUs. Socket Compatibility AMD: AM5, AM4 About the Arctic Freezer A35 A-RGB Compact CPU Cooler A-RGB Lighting The cooler comes with a 120 mm P-fan that has 12 addressable RGB LEDs that can be controlled by your motherboard software or an external controller. The fan has a plastic case that projects the light effects and creates a stunning visual impact. Pressure-optimised Fan The P-fan has a high static pressure and a wide speed range of 200 to 1700 RPM. It can deliver up to 56.3 CFM of airflow and up to 2.75 mm H2O of air pressure at maximum speed. The fan also has a fluid dynamic bearing that ensures low noise and long lifespan. Thick Heatsink The cooler has a thick heatsink block made of one piece of aluminum fins that covers the entire base plate. The heatsink measures 133 mm x 159 mm x 91 mm and has four direct-touch heat pipes that transfer heat efficiently from the CPU to the fins. MX-5 Thermal Paste The cooler comes with a syringe of ARCTIC’s new MX-5 thermal paste, which has a low viscosity and particle size that allows for a thin layer application and reduces the thermal resistance between the CPU and the cooler.
