ARCTIC Freezer 4U-M Ampere server CPU cooler

Arctic Freezer 4U-M Ampere is a compact, wide-compatibility server CPU cooler. It is compatible with Intel Xeon, AMD Ryzen, and AMD Epyc processors. It also supports the latest Ampere Altra LGA4926 processor.


Features:
Wide compatibility cooler. The Freezer 4U-M Ampere features a large contact surface and an improved mounting mechanism. It is compatible with various Intel and AMD server processors, such as Intel Xeon, AMD Ryzen, AMD Epyc, and fits LGA 4189, LGA 4677, AMD SP6, sTR5, SP3, TR4, sTRX4, and sWRX8 sockets. It also supports Ampere Altra LGA4926. Despite its impressive cooling capabilities, the Freezer 4U-M Ampere consumes only 2.88 W, ensuring exceptional efficiency in cooling even the most powerful processors with up to 64 cores and up to 350W TDP.
Designed for continuous operation. Both fans of the Freezer 4U-M Ampere feature a dual ball bearing. They allow for uninterrupted operation 24 hours a day, 7 days a week, without compromising performance. Contamination and high temperatures affect these bearings much less than conventional sleeve or fluid dynamic bearings. This is an excellent choice if you want to ensure continuous operation at maximum speed.
Compact design. The optimal installation height of the cooler is only 145 mm, fitting into classic 4U server racks and most 4U cases on the market. The Freezer 4U-M Ampere features a compact design of 156 x 124 mm. This also makes it suitable for dual-socket motherboards. If necessary, the fans can be easily swapped to adjust the airflow direction.
RAM compatibility. The Freezer 4U-M Ampere provides a spacious 53 mm RAM module height, allowing the use of memory modules with medium-sized cooling radiators. This height ensures efficient airflow and compatibility with various RAM variants.
Powerful fans with Push-Pull configuration. The installed PWM fans utilize all the advantages of the award-winning P series. Designed for static pressure, these fans are ideal for the Freezer 4U-M Ampere with its high fin density system and ensure efficient heat dissipation in push-pull mode, even in high-power applications. Office workstations, in particular, benefit from the quietly operating fans. The dual configuration also provides inherent redundancy and protects the system from complete shutdown due to overheating.
Thermal paste MX-6. The included MX-6 0.8g latest thermal paste, due to its low viscosity and particle size, allows for an extremely thin layer thickness and significantly reduces heat buildup between the processor and the cooler. At the same time, it is neither conductive nor capacitive, making it completely safe to use even for beginners.

New P series fan for better results:
Increased static pressure enhances cooling efficiency.
Extended RPM range.
Lower power consumption.
Reduced vibration.
Longer service life.
PWM for synchronous fan control.
