AIO liquid cooler with integrated LCD

The ASRock Steel Legend Dark 360 LCD is an all-in-one liquid cooler that integrates a 3.4 inch full-colour IPS display into the pump block. It uses a 397 mm aluminium radiator fitted with three 120 mm LCP fans that use dual-ball bearings. The copper cold plate mounts on AMD AM4, AMD AM5, Intel LGA 1700 and Intel LGA 1851 sockets.

Builders wanting a monitoring display

This cooler suits builders who want real-time system statistics or custom animations visible inside the case and who need directed airflow across the motherboard voltage regulators. Buyers who need a thinner radiator for a compact chassis or who prefer a pump block without an integrated screen should look at alternatives.

3.4 inch IPS LCD on the pump block

The 3.4 inch IPS LCD is the specification that determines whether this unit fits the build. It occupies the top of the 100.4 by 107.6 mm pump housing and requires clearance above the CPU socket. If the case or motherboard layout cannot accommodate that height, the cooler cannot be installed.

Questions about this item

What case clearance is needed for the 397 mm radiator and 28 mm thick fans?

The radiator is 397 mm long and each fan is 28 mm thick, so confirm your case supports a 360 mm radiator with enough depth for the fan stack.

How is the VRM cooling module attached during installation?

The dedicated VRM module mounts on the water block and connects via its own fan header; the step often missed is plugging that header in so the guided airflow actually runs.

When should the dual-ball bearing fans be checked or replaced?

Dual-ball bearing fans rated for long life typically run years without service; monitor noise and RPM through PWM control and replace only if bearing noise appears or airflow drops.
