Server cooler Arctic Freezer 4U-OneX CPU Cooler LGA5964

Arctic Freezer 4U-OneX is a server air cooler for CPU with LGA 5964 socket, aimed at stable and reliable operation under constant load. With two 120 mm fans in a push-pull configuration and serious airflow, this cooler is made for servers and workstations that run 24/7. The copper and aluminum construction, combined with dual ball bearing fans, is oriented towards long life and durability. The color is clean black, without RGB distractions – the focus is on cooling and reliability, not on effects.

What you get

You get a dual 120 mm fan unit with 400–3300 RPM, which can push up to 162 CFM of air – a serious value for cooling loaded server CPUs. The push-pull configuration means that one fan pulls air in while the other pushes it out through the radiator, improving heat exchange in tightly assembled server cases. With 53 mm RAM clearance, you have good compatibility with taller server or ECC modules, without struggling with conflicts between cooler and memory. The dual ball bearing fans and the design “Designed for continuous operation” are made for long-term use in environments where the machine is almost never turned off. The 4-pin connectors give you PWM control, so you can manage the speeds according to temperature and noise.

• Air cooling with two fans 120 mm x 2 pcs for higher efficiency under server loads.
• Support for LGA 5964 CPU socket, aimed at specific server and professional platforms.
• Wide speed range 400–3300 RPM, allowing both quiet operation at idle and aggressive cooling under load.
• Maximum airflow up to 162 CFM, suitable for densely loaded and hot server chassis.
• Push-pull configuration of the fans for better airflow through the radiator and lower temperatures.
• 53 mm RAM clearance, so you can combine the cooler with taller RAM modules without physical conflict.
• Durable dual ball bearing fans and design “Designed for continuous operation” for 24/7 operation in a server environment.
• Combination of copper and aluminum for a good balance between thermal conductivity and weight, which here is a serious 1479 g.
• No RGB effects, with a clean black design focused on functionality and easy integration into server configurations.
• Long warranty of 72 months, which is important for hardware that runs continuously.

Who it is suitable for

This cooler is for server and workstation builds with LGA 5964, where stability, long life, and 24/7 operation are more important than compactness or RGB aesthetics. It is suitable if you are looking for a serious air cooler for loaded CPUs in rack or tower servers, with enough space for a heavy cooler. It is not the best choice for small cases or lightweight desktop configurations, where weight and size can be an issue.

The most impressive aspect is the combination of high airflow, push-pull configuration, and orientation towards continuous operation, reinforced by the long 72-month warranty – exactly what you want from a server CPU cooler.
