Arctic Freezer 36 CO – Black



High-Class Finish with Aluminium Top Plate

With its push-pull configuration, the Freezer 36 CO not only impresses with its efficient cooling performance, but also with its design. The soldered ends of the heatpipes are concealed by the screwed aluminium cover, allowing it to blend seamlessly into any PC setup and highlight both performance and appearance.

Future-Proof Compatibility

The Freezer 36 CO is multi-compatible with Intel and AMD sockets. Intel will release the new Arrow Lake processors on the LGA1851 socket in the future. ARCTIC customers don’t need to worry that the new CPUs will also require new coolers. We guarantee full compatibility. All Freezer 36 CO can be used with the new LGA1851 socket from Intel without limitation.

Improved Fan Mounting

Thanks to the innovative mounting system, booth fans are effortlessly mounted in the heatsink using a click system. This mounting method eliminates the need for fan clips, making it easier to install the cooler or replace the fans, even if the cooler is already installed. The Freezer 36 CO is therefore compatible with most 120 mm fans.

LGA1851 | LGA1700 Contact Frame

Intel’s Independent Loading Mechanism (ILM) deforms the CPU by pressing it into the socket at two points with over 40 kg. This causes pressure in the PCB, the DIE and the solder layer between the DIE and IHS (Integrated Heat Spreader). With high thermal load, this can lead to long-term problems. The mounting frame from ARCTIC does not deform the CPU, reduces the mechanical load on the CPU massively, is quick and easy to install and allows the cooler to be screwed onto the CPU’s backplate. As a result, mechanical stress on the mainboard and CPU is minimised, cooling performance remains consistent and installation is quick and uncomplicated.

Designed for Continuous Operation

Both fans of the Freezer 36 CO are each equipped with two japanese ball bearings. This makes these fans particularly durable and resistant to external forces such as heat, dust and vibrations. This variant is therefore the ideal choice for 24/7 operation.

Optimised Heatsink

The fins of the heatsink are open at the side and allow the pull fan to draw additional cool air out of the pc case through the heatsink. This side-flow design achieves even more efficient ventilation.

P-Fans with High Static Pressure

ARCTIC relies on the proven P fans, which are known for their powerful performance. The P series is particularly suitable for use on heat sinks and radiators. Due to the dense fin structure of heat sinks, the fans used achieve significantly better performance than fans designed for airflow thanks to their high static pressure.

Large Selection of Variants

The Freezer 36 is available in five different versions, all equipped with two fans in a push-pull configuration. In addition to the standard model with aluminium heatsink design, a version with a black heatsink is also available. For continuous operation, there is also the CO version, which is equipped with fans with double ball bearings. Alternatively, users can choose between a black and a white version with A-RGB fans.
