CPU cooler ARCTIC Freezer 4U-M Rev.2 - ACFRE00133B

ARCTIC Freezer 4U-M Rev.2 is a serious air cooler for processors, aimed at workstation and server platforms, rather than typical gaming builds. It supports a wide range of high-end sockets such as sTRX4, TR4, Server SP3, sWRX8, LGA 4677, and LGA 4189, making it a good choice for powerful CPUs with many cores. With two 120 mm fans and a copper construction, it is designed for stable cooling under long loads. There is no RGB and it has a clean silver appearance – function-oriented, not about „bling“.

What you get

You get a dual-fan air cooler with dimensions 124 x 156 x 145 mm, optimized for platforms with large CPUs and heavy loads – rendering, virtualization, data processing. The two fans sized 120 mm, connected via a 4 PIN connector, allow PWM control, so you can keep the RPM between 400 and 2300 RPM depending on the load. The copper material provides better thermal conductivity compared to standard aluminum solutions, which is important for high core-count CPUs. The noise level up to 40 dB is reasonable for a class of coolers that need to keep serious TDP under control, especially in closed cases or server chassis.

• High-end air cooling based on copper, for more efficient heat transfer from powerful processors.
• Wide compatibility with professional and server platforms: sTRX4, TR4, Server SP3, sWRX8, LGA 4677, LGA 4189, sTR5, SP6, sTRX8, making it a versatile choice for HEDT and server builds.
• Two fans sized 120 mm, providing better airflow through the radiator in a push-pull configuration.
• Wide range of rotation speeds from 400 to 2300 RPM, allowing you to balance between cooling and noise depending on the load.
• 4 PIN connectors on the fans allow PWM control from the motherboard for smarter profiles and lower noise in idle.
• Maximum noise level around 40 dB, suitable for a workstation or server where stability under load is a priority.
• Compact for the class dimensions 124 x 156 x 145 mm and a clean silver design without RGB – a practical choice for a professional environment.

Who it is suitable for

This cooler is suitable if you are building a workstation or server on platforms like TR4, sTRX4, SP3, LGA 4677 and similar, and want reliable air cooling instead of a more complex water solution. It is good for 24/7 loads – rendering, CAD, simulations, virtualization, databases. If you aim for a small, quiet home PC with a normal desktop socket and RGB effects, this is probably not your product.

The most sensible aspect here is the combination of wide compatibility with server and HEDT sockets, copper design, and two 120 mm fans with PWM control, which provides stability and flexibility for serious configurations.
