Dissipador de CPU Arctic Freezer 4U-M Ampere Server – solução passiva/dissipador para servidores Ampere, 120W TDP

Versatile Multi-Compatible Server Cooler

The Freezer 4U-M Ampere stands as a multi-compatible server cooler, boasting an expansive contact surface and an enhanced mounting mechanism. It now offers compatibility with a wide range of Intel and AMD server processors, including Intel's LGA4710, LGA 4189 and LGA 4677, as well as AMD's SP6, sTR5, SP3, TR4, sTRX4, and sWRX8 sockets. It also supports the Ampere Altra LGA4926. Remarkably, despite its impressive cooling capabilities, the Freezer 4U-M Ampere consumes a mere 2.88 watts, ensuring exceptional efficiency in cooling even the most powerful processors with up to 64 cores and a TDP of up to 350 watts.

RAM Compatibility and Clearance

The Freezer 4U-M Ampere offers a generous 53 mm of clearance for memory, allowing the use of RAM modules with moderate heatsinks. This space facilitates efficient airflow and ensures compatibility with various types of RAM.

Compact Design and Dual Socket Compatibility

With an optimised installation height of only 145 mm, it fits into both classic 4U server racks and most consumer 4U cases available on the market. The Freezer 4U-M Ampere features a compact design with dimensions of just 156 x 124 mm. This also makes it suitable for dual-socket motherboards. To adjust the airflow direction if required, the fans can be easily swapped over.

Powerful Fans in Push-Pull Configuration

The installed PWM fans benefit from all the advantages of the award-winning P series. Designed for static pressure, the fans are ideal for the Freezer 4U-M Ampere's high fin density and provide efficient heat dissipation in push-pull mode, even in power-hungry applications. Especially office workstations benefit from the quiet fans. The dual configuration also allows for inherent redundancy and protects the system from total shutdown caused by heat.

Designed for continuous operation

Both fans of the Freezer 4U-M Ampere are equipped with dual ball bearings, which allows for 24/7 continuous operation without the slightest compromise in performance. This type of bearing is much more resistant to contamination and wear caused by high temperatures than conventional sleeve bearings or Fluid-Dynamic bearings and is therefore the perfect choice if you want to ensure fault-free continuous operation.

Premium Thermal Paste Included

The Freezer 4U-M Ampere comes with MX-6 thermal paste. ARCTIC's Ultimate Performance thermal paste reduces the heat build-up between the heat spreader of the CPU and the cooler. The thermal paste is neither conductive nor capacitive and therefore absolutely safe to use.

How to use

Install the heatsink on the server CPU following the server manufacturer's CPU retention and mounting instructions, ensuring proper alignment with the socket and mounting points. Apply an appropriate thin layer of thermal interface material between the CPU heat spreader and the heatsink base to ensure efficient heat transfer. Secure the heatsink using the provided mounting mechanism and verify that chassis airflow direction matches the heatsink's intended orientation for passive dissipation. After installation, monitor CPU temperatures under typical load to confirm adequate cooling performance.

Recommendations

Use this passive heatsink in systems where chassis airflow is consistent and unobstructed; avoid placing obstructions above or below the heatsink that could hamper convective flow. For racks with variable airflow or higher ambient temperatures, consider supplemental chassis fans or active cooling to maintain safe operating temperatures for sustained workloads.
