What the product is

The ASRock Steel Legend 360 LCD is an all-in-one liquid cooler with a 360 mm radiator and a 3.4 inch full-colour IPS LCD on the pump block. It fits AMD Socket AM4, AM5 and Intel LGA 1700, 1851 platforms. The three 120 mm fans use liquid-crystal polymer blades and dual-ball bearings for long life.

Installation notes

The radiator measures 397 mm long and 27 mm thick, so verify case clearance before mounting. The pump block is 100.4 mm wide, 86 mm deep and 107.6 mm tall; check RAM and VRM heatsink clearance around the socket. A dedicated VRM cooling fan clips onto the block and adds height. Fans connect via standard 4-pin PWM headers.

The deciding specification

The pump runs between 1200 and 3100 RPM with a 3-phase, 6-slot, 4-pole motor and dual-side inlet path. Maximum fan speed is 2500 RPM delivering 76.70 CFM at 38.3 dB(A). If your workload needs sustained flow at lower acoustic levels, this spec determines suitability.

Questions about this item

How do I confirm the 3.4" LCD is displaying real-time stats after installation?

Open the Polychrome DISPLAY software and verify that CPU temperature, pump speed between 1200 and 3100 RPM, and fan speeds up to 2500 RPM appear on the 3.4" IPS LCD in real time.

What comes in the box and which mounting hardware must be purchased separately for AM5 or LGA 1851?

The box contains the 360 mm radiator, three 120 mm LCP fans with dual-ball bearings, the pump block with integrated VRM fan, and mounting brackets for AM4, AM5, LGA 1700, and LGA 1851 — no extra brackets are required for those sockets.

Which version should I choose if my case only fits a 27 mm thick radiator and I need white aesthetics?

This white version has a 27 mm thick radiator measuring 397 mm in length, matching cases limited to that thickness while providing the full 360 mm cooling surface.
