ARCTIC Freezer 36 CO CPU Air Cooler

Get 24/7 reliability with the ARCTIC Freezer 36 CO CPU Cooler. Built for continuous operation featuring dual Japanese ball bearing 120mm PWM PST fans. Continuous Operation CPU Cooler, Dual Ball Bearing Cooler, Single Tower CPU Air Cooler, Intel LGA1851 LGA1700, AMD AM5 AM4.

Overview (Easy-to-Understand Description)

The ARCTIC Freezer 36 CO (Continuous Operation) is a heavy-duty single-tower CPU air cooler engineered specifically for setups that run 24/7 without stopping. Utilizing two P12 PWM PST CO fans arranged in a push-pull configuration, it delivers consistent heat dissipation for long work sessions, servers, and non-stop gaming rigs.

Unlike standard PC fans, the "CO" edition features premium Japanese dual ball bearings. These high-durability bearings are significantly more resistant to heat, dust, and continuous wear, ensuring an exceptionally long lifespan. The cooler includes an elegant screwed aluminium top cover that conceals heatpipe ends and ships with ARCTIC MX-6 thermal paste included in the box.
