ARCTIC has introduced the Freezer 4U-Altra, a new air cooler designed specifically for server and workstation platforms powered by Ampere Altra processors. Engineered for demanding workloads and continuous operation, the cooler supports the Ampere Altra LGA4926 socket and offers a compact form factor suitable for standard 4U server racks and workstation chassis.
Designed for efficient heat dissipation under sustained loads, the Freezer 4U-Altra employs a dual-fan push-pull configuration to maximise airflow while maintaining moderate noise levels. The cooler targets professional environments where reliable thermal performance and long-term operational stability are critical, including data centres, edge computing deployments, and high-performance workstations.
The ARCTIC Freezer 4U-Altra features several design elements tailored for enterprise and workstation applications:
• Compact 145 mm height designed to fit standard 4U server racks and most 4U chassis
• Support for the Ampere Altra LGA4926 processor socket
• Dual 120 mm PWM-controlled P-series fans configured in a push-pull arrangement
• High-static-pressure fan design for effective airflow through dense heatsink fins
• Dual ball bearing fans engineered for enhanced durability and continuous 24/7 operation
• Wide PWM speed range for balancing cooling performance and power efficiency
ARCTIC highlights the Freezer 4U-Altra's suitability for compact server and workstation systems that require dependable cooling performance under sustained workloads. The use of dual ball bearing fans is intended to reduce wear over time, while the pressure-optimised fan design helps maintain effective cooling performance in space-constrained environments.
