Atmos II 360 LCD AIO Liquid Cooler

This 360 mm all-in-one cooler combines a dual-chamber pump, three 120 mm ARGB PWM fans and a customisable LCD screen on the pump head. It targets enthusiasts building high-performance Intel or AMD systems who want strong thermal capacity plus a visible display for temperatures, images or animations. The white finish and magnetic top covers suit clean, light-themed builds. Pre-installed fans and hidden tube wiring speed up assembly.

Builders wanting integrated monitoring

The LCD screen and single-cable fan hub help users who prefer at-a-glance coolant temps or custom graphics without extra software layers. Offset brackets for LGA 1851 are included for optimal contact on newer Intel sockets. Buyers who need a smaller radiator for compact cases or who want a non-LCD pump head to save cost should look at other models in the range.

394 mm radiator length

The radiator measures 394 mm long, so the case must support a 360 mm class radiator with enough clearance for 394 mm overall length and 30 mm fan thickness. Verify the mounting area and tube routing space before purchase. If the chassis cannot accommodate this length, the cooler will not fit.

Questions about this item

How can I confirm the pump is running at its rated 3400 RPM after installation?

Use motherboard software or BIOS to monitor the pump header; it should report a speed near 3400 RPM and the pump noise should stay around 25 dB(A).

What comes in the box and what must I source separately?

The box contains the 360 mm radiator, pump block with two magnetic covers, three pre-installed 120 mm ARGB PWM fans, offset brackets for LGA 1851, standard brackets for AM4, AM5, LGA 1150, 1151, 1155, 1156, 1200, 1700 and 1851, plus all mounting hardware. Thermal paste is not included.

Which version should I choose for an Intel Core Ultra processor on LGA 1851?

This single white 360 mm model includes the required offset mounting brackets for LGA 1851, delivering up to 4 °C lower core temperatures on that socket.
