Multi-Socket CPU Air Cooler

The ARCTIC COOLING Freezer 36 is a tower-style CPU air cooler designed for builders using Intel LGA1700, LGA1851 or AMD AM4 and AM5 sockets. It fits mainstream desktop processors where a 159 mm height clearance exists. It is not for buyers who need liquid cooling or low-profile coolers for small-form-factor cases.

Push-Pull Dual-Fan Configuration

Two 120 mm pressure-optimised fans run in push-pull at 200 to 1800 rpm under PWM control, stopping completely below 5 % duty cycle. Direct-touch copper heatpipes and an aluminium fin stack transfer heat from the CPU. No RGB lighting is included.

Straightforward Mounting With Height Check

The cooler uses a vertical fan-mounting system and includes brackets for the listed Intel and AMD sockets. Installation is simplified compared with earlier Freezer models. Verify that your case allows 159 mm of cooler height and that the 890 g weight is supported by the motherboard.

Questions about this item

What does the 1800 rpm top speed mean for actual cooling inside a case?

The fan can spin up to 1800 rpm under load, pushing more air through the heatsink for higher heat dissipation, and drops to 0 rpm below 5 % PWM for silent idle.

How does the 4-pin PWM connector limit or enable fan control?

The 4-pin PWM connector lets the motherboard regulate speed precisely from 200 to 1800 rpm, including a 0 rpm mode at very low duty cycles.

Will the 159 mm height fit in my mid-tower case?

The cooler stands 159 mm tall, so it fits most mid-tower cases that accept CPU coolers up to that height.
