360mm AIO with VRM fan

The Cooler Master Atmos II is a 360mm all-in-one liquid cooler that includes a dedicated VRM cooling fan and three 120mm ARGB PWM fans. It supports a wide range of modern AMD and Intel desktop sockets including AM4, AM5, LGA 1700 and LGA 1851. A dual-chamber pump design aims to increase water pressure and target the CPU hot spot directly. Wiring is routed inside the tubing for a cleaner internal appearance.

Builders who want integrated VRM airflow

This cooler suits builders who want VRM cooling integrated into the AIO unit without adding separate case fans for that purpose. It is not for systems that cannot accommodate a 394mm radiator or three 120mm fan slots. It is not for users who prefer air cooling or who need a smaller radiator for compact chassis. The included offset mounting brackets specifically address LGA 1851 hotspot alignment.

394mm radiator length

The radiator measures 394mm in length, which determines whether it fits your case and mounting location. Verify your chassis supports this exact radiator size and three 120mm fan positions before purchase. The pump operates at 3400 RPM with a noise rating of 25 dB(A), while fans reach 2500 RPM and 38.5 dB(A) at maximum speed.

Questions about this item

How long is the pump rated to run at 70°C before it might need replacement?

The pump is engineered to endure 70°C for 3,000 hours and 120°C for 12 hours using PPS and fiberglass construction for lasting performance.

Which component hits its thermal limit first when the cooler runs continuously at full load?

The pump is validated to withstand 70°C for 3,000 hours and 120°C for 12 hours, defining the primary thermal endurance limit under sustained operation.

What noise level should I expect from the fans and pump when the system runs all day?

The pump operates at 25 dB(A) while the three 120 mm fans reach 38.5 dB(A) at maximum 2,500 RPM, giving a combined acoustic profile under continuous load.
