The Arctic Freezer 4U-M stands out for its exceptionally broad compatibility, as it is designed to support enterprise processors from the leading manufacturers in the market. It is fully compatible with Intel LGA4710, LGA4189, and LGA4677 sockets, as well as the powerful AMD SP6, sTR5, SP3, TR4, sTRX4, and sWRX8 platforms for EPYC and Threadripper processors. In addition, it meets the needs of ARM architectures by supporting the Ampere LGA4926 socket, making it a universal solution for modern servers and high-demand workstations.

The dimensions of the heatsink are meticulously designed at 124 (L) x 156 (W) x 145 (H) mm, to offer a perfect fit in Server Rack Units of size 4U and above. This compact component layout allows for easy integration into standard rackmount cases without obstructing airflow or other internal server components. With a total weight of 1275 g, it provides the sturdiness and surface area required to handle the massive thermal loads of multi-core processors, keeping your hardware safe.

The heatsink system of the cooler incorporates 8 copper heat pipes with Direct Touch technology, 6 mm in diameter, which come into direct contact with the clear integrated heat spreader (IHS) of the processor. This technology eliminates thermal resistance and allows instant heat transfer to the body of the cooler. The heatsink consists of 57 aluminum fins (fin material: aluminium), which are precisely arranged to maximize the cooling surface and efficiently dissipate heat.

For optimal airflow, Arctic equips the cooler with 2 x 120 mm PWM fans operating in a push-pull configuration. Their speed is dynamically controlled via PWM and ranges from 400 to 2300 rpm, allowing the system to adjust the rotations according to the current server load. Connection is easily made via a 4-Pin Plug with a 200 mm cable length, offering clean cable management and immediate response to motherboard commands.

The fans are manufactured with Dual Ball Bearing technology, which is the most suitable for servers, as it offers tremendous durability over time and allows continuous operation without wear. They produce an impressive airflow that reaches 71.90 cfm | 122.16 m³/h and exceptionally high static pressure of 3.30 mmH2O, forcing air through the dense fins. Despite their enormous power, the maximum noise level is limited to 40 dBA.

The Arctic Freezer 4U-M is a complete value-for-money solution, as the package includes a syringe with the award-winning ARCTIC MX-6 0.8 g thermal paste. This particular paste offers top thermal conductivity and is non-conductive, ensuring absolute safety during application. The cooler is designed to operate flawlessly across a wide range of ambient temperatures from 0 to 40 °C, providing the maximum possible stability required by any professional data center.
