360 mm AIO for mainstream and enthusiast CPUs

The Cooler Master Atmos II 360 uses a 394 mm aluminum radiator and three 120 mm ARGB PWM fans to dissipate heat from modern AMD and Intel sockets. It targets builders who want strong thermal performance with a clean white aesthetic and integrated LCD customisation.

Single 7-pin PWM plus ARGB cable limits routing

All three fans and the pump draw power and lighting control through one 7-pin connector, so the motherboard must supply enough current on a single header. The loop dynamic bearing fans spin between 690 and 2500 RPM, delivering up to 322.8 m³/h of airflow at the cost of increased noise at the top end.

Dual-chamber pump rated for 3400 RPM and 25 dB(A)

The offset mounting brackets for LGA 1851 can lower core temperatures by up to 4 °C, while the pump is validated at 70 °C for 3000 hours and 120 °C for 12 hours. Builders chasing extreme overclocks or silent operation at idle may find the fixed pump speed and 400 mm tube length restrictive.

Questions about this item

Which Cooler Master Atmos II 360 variant should I pick for a white-themed build?

This MPN MLX-D36M-A25SZ-LW is the white edition with a 360 mm radiator, three white 120 mm ARGB fans and a white pump housing, so it matches a white build out of the box.

What does the 3400 RPM pump speed actually deliver inside a case?

The dual-chamber pump runs at a fixed 3400 RPM and is rated at 25 dB(A), pushing coolant straight to the CPU hot spot while keeping audible noise low in typical chassis airflow.

How does the 7-pin PWM ARGB connector limit fan control?

Each 120 mm fan uses a single 7-pin cable that carries both PWM speed signals (690–2500 RPM) and ARGB data, so fan curves and lighting sync through one motherboard header per fan.
