CPU cooler Arctic Freezer 4U SP5 Server CPU Cooler - ACFRE00158A

The Arctic Freezer 4U SP5 is a serious air cooler aimed at server and HEDT configurations with AMD SP5 processors. It is designed to handle up to 360 W TDP and even processors with up to 128 cores, according to the manufacturer. With two 120 mm fans in a push-pull configuration and a massive copper and aluminum radiator, this is a solution for systems that run under load all day. The compact dimensions and 53 mm RAM clearance help you fit it into dense server chassis without compromising cooling.

What You Get

You get an air cooler with a cooling capacity of 360 W, designed for continuous operation in a server environment. The two 120 mm fans with a range of 300 to 3300 RPM offer flexibility – from relatively quiet idle to aggressive airflow under full load. With an air flow of 162.08 CFM and maximum pressure of 4.35 mmH2O, this cooler is prepared to push air through denser radiator fins and restricted air channels in server cases. The included MX-6 thermal paste saves the need for an additional purchase and ensures quality contact from the first installation. Dual Ball Bearing bearings and the design for continuous operation are key if your machine needs to run 24/7 without drama.

• Designed specifically for the AMD SP5 socket, so it fits directly on modern server and professional platforms.
• Cooling capacity up to 360 W, which allows cooling even the most powerful AMD processors with up to 128 cores according to the manufacturer.
• Two 120 mm fans in a push-pull configuration ensure high flow and more efficient heat dissipation from the radiator.
• Wide speed range from 300–3300 RPM via a standard 4-pin connector, so you can rely on PWM control according to the load.
• Air flow up to 162.08 CFM and maximum pressure 4.35 mmH2O, which is important for dense radiator fins and restricted air path in server cases.
• Official 53 mm RAM clearance, which helps you avoid conflicts with taller server ECC modules.
• Uses a combination of copper and aluminum for an optimal balance between thermal conductivity and weight, in a housing with dimensions 124 x 147 x 145 mm.
• Dual Ball Bearing bearings and the „Designed for Continuous Operation“ design are aimed at 24/7 operation with longer fan life.
• Includes high-quality MX-6 thermal paste, so you can install and launch the system immediately, without additional consumables.
• Clean black and silver design without RGB, focused on functionality and reliability, not a light show.

Who is it suitable for

This cooler is for system administrators, workstation users, and enthusiasts who build an SP5 server or a professional machine running under high load 24/7. It is suitable if you aim for stable temperatures and reliability with high TDP processors, rather than seeking RGB effects or compact mini-ITX solutions. If you have a desktop platform or a lighter CPU, this is already overkill and there are more logical and budget-friendly options.

The strongest point of the Arctic Freezer 4U SP5 is the combination of high cooling capacity, push-pull configuration, and design for continuous operation, aimed precisely at loaded server and professional systems where stopping is not an option.
