Server Cooler specifically designed for AMD SP5

Server Cooler specifically designed for AMD SP5

The Freezer 4U-SP5 is specially designed for Socket SP5 and supported EPYC processors. With a maximum power consumption of only 6.96 W, the Freezer 4U-SP5 cools even the most powerful AMD processors with 128 cores and 360 W TDP extremely efficiently.

RAM Compatibility and Clearance

The Freezer 4U-SP5 offers a spacious 53 mm of RAM clearance, allowing for the use of memory sticks with moderate heatsinks. This clearance allows efficient airflow and enables compatibility with different RAM variants.

Powerful Fans in Push-Pull Configuration

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-SP5'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.

Premium Thermal Paste Included

The Freezer 4U-SP5 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.

Designed for Continuous Operationn

Designed for Continuous Operationn

Both fans of the Freezer 4U-SP5 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.

How to use

Install the cooler according to the chassis and motherboard layout: align the mounting interface with the SP5 socket and secure the unit using the provided mounting hardware. Ensure the cooler is positioned to allow unobstructed airflow through the heatsink and fan area; verify that RAM modules or expansion cards do not interfere with the low-profile unit. Connect the fan power cable to the motherboard fan header and configure fan control in firmware or operating system utilities to match desired performance and noise characteristics.

Recommendations

For reliable operation, use the Arctic Freezer 4U-SP5 in systems with processor thermal loads up to 120W TDP. Maintain clear airflow paths within the chassis, perform periodic dust cleaning of the heatsink and fan, and set sensible fan curves in BIOS/UEFI to balance cooling and acoustic requirements. Verify mechanical compatibility with your specific 4U or rackmount case before installation.
