Arctic Freezer 36 CO CPU Cooler - ACFRE00122A

Arctic Freezer 36 CO is an air CPU cooler from mid to high class, aimed at stable and quiet operation, rather than flashy RGB shows. It comes with two 120 mm fans in a push-pull configuration and decent airflow, making it a good candidate for more demanding systems. It is compatible with modern sockets AM4/AM5 and LGA1700/LGA1851, which means you can comfortably consider it for future upgrades. The aluminum top plate and silver design give it a clean, finished look in the case.

What you get

The two included 120 mm fans, spinning in the range of 200–1800 RPM, provide a good balance between cooling and noise, maintaining around 22.5 dBA during normal operation – quite decent for a dual-fan cooler. The airflow of up to 112.6 CFM and maximum static pressure of 2.2 mmH2O help effectively blow through the radiator, which is important under prolonged load. The 4-pin connector gives you PWM control through the motherboard, allowing you to set an aggressive or quiet curve depending on whether you are aiming for silence or temperatures. The dimensions 104 x 126 x 159 mm and height 159 mm are key to check compatibility with the case and RAM modules. Improved mounting for the fans and a special LGA1851/LGA1700 contact frame are also included, helping achieve more even pressure and better contact with the CPU.

• Air cooling with two 120 x 120 x 25 mm fans for more effective expulsion of warm air from the radiator.
• Wide RPM range 200–1800 RPM via 4-pin PWM connector, allowing you to adjust behavior from nearly silent to maximum performance.
• High airflow up to 112.6 CFM, which is important if you often keep the CPU under serious load.
• Low noise level of around 22.5 dBA, suitable for gaming and work in a quiet environment without annoying whine.
• Static pressure of 2.2 mmH2O, helping the air pass tightly through the radiator fins and effectively dissipate heat.
• Compatibility with modern sockets AM4, AM5, LGA1700, and LGA1851, making it a good choice for future platforms.
• Aluminum radiator and High-Class Finish with Aluminium Top Plate in silver color for a clean, neutral look without RGB.
• Improved Fan Mounting and LGA1851/LGA1700 Contact Frame for easier installation, stable attachment, and better contact with the CPU heatspreader.

Who it is suitable for

Freezer 36 CO is a good choice for gaming and work configurations where you want serious air cooling with two fans, without switching to water cooling. It is suitable if you are on AM4/AM5 or LGA1700/LGA1851 and are considering an upgrade within the same platform. If you are aiming for a fully RGB look or have a very low budget build, it may not be the best fit for you.

The combination of dual-fan configuration, high CFM, and low noise, plus future-proof compatibility with new Intel and AMD sockets, makes Arctic Freezer 36 CO a practical and sensible choice for a stable and long-term system.
