The Arctic Freezer 4U-M Rev. 2 CPU cooler features an extended contact surface and a mounting mechanism for compatible Intel and AMD server processors. Its two PWM fans operate in a push-pull configuration and are designed for static pressure to dissipate heat from the dense fin array. Its height allows installation in 4U racks and compatible 4U PC cases, while the fans can be repositioned to change the airflow direction.

The cooler supports RAM modules with heatsinks, thanks to its 53 mm clearance, and is suitable for motherboards with two processor sockets. The fans feature dual ball bearings for continuous 24/7 operation. MX-6 thermal paste is included.
