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

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 of heat dissipation and even with 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 fit it into tight server chassis without sacrificing 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 allow flexibility – from relatively quiet idle to aggressive airflow under full load. With a total airflow of 162.08 CFM and maximum pressure of 4.35 mmH2O, this cooler is ready to push air through denser radiator fins and limited airflow channels in server cases. The included thermal paste MX-6 saves the need for an additional purchase and ensures quality contact right from the first installation. Dual Ball Bearing type bearings and the design for continuous operation are key if your machine needs to run 24/7 without drama.

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

Who it is suitable for

This cooler is for system administrators, workstation users, and enthusiasts building an SP5 server or professional machine running under high load 24/7. It is suitable if you are aiming for stable temperatures and reliability with high TDP processors, and not looking for RGB effects or compact mini-ITX solutions. If you are on a desktop platform or lighter CPU, this is already overkill and there are more logical and budget-friendly options.

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