360 mm AIO for high-end CPUs

The MasterLiquid 360 Atmos Stealth is an all-in-one liquid cooler built around a 394 mm aluminium radiator and three pre-installed 120 mm Mobius PWM fans. It mounts on AMD AM4, AM5 and Intel LGA 1150 through 1851 sockets, targeting R9 and i9 processors that demand sustained heat removal.

Dual-chamber pump and Mobius fans

A patented dual-chamber pump isolates hot and cold coolant paths to increase pressure at the CPU hotspot while keeping pump noise below 25 dBA. The bundled Mobius 120 fans use interconnected ring blades and loop dynamic bearings to deliver up to 75.2 CFM at 2,400 RPM with a maximum static pressure of 3.63 mmH2O, and fan noise is rated at 30 dBA.

Headroom for overclocked 9-class chips

The 360 mm radiator surface and high-flow pump combination comfortably handle the thermal output of overclocked R9 and i9 CPUs under sustained loads. The cooler runs out of capacity when total package power exceeds the dissipation limit of the aluminium radiator and three 120 mm fans, making custom loops the next step for extreme voltage scenarios.

Questions about this item

How often should I check or replace the coolant in this sealed 360 mm AIO loop?

The MasterLiquid 360 Atmos Stealth is a factory-sealed AIO with no user-serviceable coolant ports; under normal use the loop does not require refilling or scheduled fluid replacement.

What thermal limit will the dual-chamber pump hit first during a sustained all-core load on an i9 or R9?

The pump is rated below 25 dBA and the three Mobius fans peak at 2400 RPM with 3.63 mmH₂O static pressure; the practical ceiling is the radiator's ability to reject heat once fan speed and coolant temperature stabilise.

How loud and hot does the unit get when the three 120 mm fans run at full 2400 RPM all day?

At maximum speed the fans produce 30 dBA and move 75.2 CFM each; the pump stays under 25 dBA, so total acoustic output remains low while the 394 mm aluminium radiator handles the heat load.
