Dual 120 mm fans in push-pull cool Intel LGA1700, LGA1851 and AMD AM4, AM5 sockets with PWM control from 200 to 1800 rpm
Model Freezer 36 CO
The Freezer 36 CO is a dual-fan CPU air cooler built for Intel LGA1851 and LGA1700 plus AMD AM5 and AM4 sockets. It uses direct-touch heatpipes covered by an aluminium top plate and two 120 mm pressure-optimised fans in a push-pull layout. Dual ball bearings and PWM control let the fans spin from 200 to 1800 rpm, stopping completely below five percent duty cycle for silent idle operation.
The cooler stands 159 mm tall and weighs 890 g, so the case must clear that height and the motherboard must handle the mass. Vertical fan mounting keeps the heatsink footprint narrow, leaving RAM slots and PCIe brackets accessible on most boards. A single 4-pin PWM header drives both fans through the included splitter cable, and the non-LED design adds no lighting load to the system.
This model replaces the Freezer 35 and Freezer 34 eSports DUO with simplified mounting and higher tested throughput. Builders moving from a stock cooler or an older tower design gain lower load temperatures and quieter acoustics without changing platform. Users who need a smaller height limit or a single-fan layout should look elsewhere, as the push-pull array and 159 mm profile are fixed.

Other versions of this model
The cooler stands 159 mm tall, so the case must provide at least that much CPU-cooler clearance; measure from the motherboard tray to the side-panel window or fan mount before buying.
At 1800 rpm the dual ball-bearing fans move more air, raising noise and exhaust heat; PWM lets the motherboard drop speed to 200 rpm or stop at 0 rpm below 5 % duty for quiet idle.
You need an Intel LGA1700 or LGA1851, or AMD AM4 or AM5 socket, plus a 4-pin PWM fan header for the 4-pin connector and the included 4-pin plug.
