Arctic Freezer 4U-Altra CPU Cooler Hits $80 for Ampere Altra Servers

Server administrators managing Ampere Altra processors now have a dedicated cooling solution designed for high-density environments. The release of the Freezer 4U-Altra addresses the specific thermal requirements of 350W processors in 4U rack-mounted systems. This hardware allows data center operators to maintain stable operating temperatures without compromising on airflow or noise levels.

Dual-fan cooler supports 350W TDP in 4U rack systems

Arctic introduced the Freezer 4U-Altra as a dual-fan CPU cooler specifically engineered for the LGA4926 socket. The product includes a dedicated mounting kit compatible with both Ampere Altra and Altra Max processors. This targeted design ensures proper fitment and thermal contact for these specific server-grade chips.

Specifications

• Socket Compatibility: LGA4926
• TDP Support: 350W
• Heat Pipes: 8x 6mm
• Fan Model: Arctic P Series 120mm
• Fan Bearing: Dual Ball Bearing

The cooler utilizes eight 6mm heat pipes to transfer heat away from the processor. It supports a maximum Thermal Design Power (TDP) of 350W. The unit incorporates two Arctic P Series 120mm fans that run at speeds between 400 and 2,300 RPM. These fans use dual ball bearings for longevity and deliver an airflow of 17.9 CFM.

The physical dimensions of the cooler are 124 x 156 x 145 mm, with a total weight of 1,288 grams. The low profile height of 145 mm allows it to fit within standard 4U rack constraints. The unit operates at a noise level of 0.5 Sone and includes MX-7 thermal paste for installation.

The Freezer 4U-Altra is available globally with a manufacturer's suggested retail price of 69.99 EUR (around $79.90). Sales began on June 30, 2026. We touched on ARCTIC Freezer 36-S Air Cooler Launches in our earlier Arctic coverage.

Arctic has confirmed the immediate availability of this server-focused cooling solution. The product meets the specific socket and TDP requirements for Ampere Altra processors. It provides a quiet and compact thermal management option for 4U rack deployments.
