  • Dissipates heat efficiently via two 120 mm fans running 300-3300 RPM with PWM control
  • Runs reliably 24/7 thanks to double ball bearing fans built for continuous operation
  • Installs quickly with pre-fitted brackets and included thermal paste
  • Handles high-output AMD EPYC SP5 processors using ten heatpipes on LGA6096 socket

Compact 4U Server Cooler for AMD SP5

The ARCTIC Freezer 4U-SP5 is a dedicated air cooler built for AMD EPYC processors using the LGA6096 socket. Its low-profile design fits inside standard 4U chassis and leaves RAM slots fully accessible. The unit supports dual-CPU motherboards without interference. It targets administrators who need reliable thermal management in dense rack environments.

PWM Fans and Ten Heatpipes for Continuous Load

Two custom 120 mm fans run between 300 and 3300 RPM via a 4-pin PWM connector for precise speed control. Double ball bearings are rated for 24/7 operation. Ten heatpipes transfer heat from the CPU to the aluminium fin stack. The cooler handles sustained server workloads while keeping acoustic output proportional to demand.

Pre-Fitted Brackets and Paste Simplify Deployment

Thermal compound is included in the package. Mounting brackets come pre-installed on the heatsink and use the platform's native mounting points. No extra hardware or backplate is required. This reduces installation time during initial build or field replacement. The bundle omits fan splitters or RGB software.

Questions about this item

How do I install the Freezer 4U-SP5 on an AMD SP5 socket, and which step is most often missed?

Use the pre-installed mounting brackets that match the LGA6096 pattern, apply the included thermal paste, then secure the cooler; the step most often missed is confirming the brackets are locked onto the exclusive mounting points before tightening the screws.

What maintenance will the 120 mm fans need during 24/7 server operation?

The double ball bearing fans are rated for continuous use; no routine lubrication is required, but dust should be cleared from the heatsink fins and fan blades periodically to maintain airflow.

At what fan speed does the cooler hit its thermal limit under sustained EPYC workloads?

The PWM fans spin between 300 and 3300 RPM; the thermal limit appears first when the 10 heatpipes and dual fans can no longer dissipate the CPU's heat at maximum RPM.
