InWin IW-RL400 — 4U Liquid-Cooled Rackmount Chassis with 360 mm AIO

Specifications

Overview

The InWin IW-RL400 brings factory-integrated liquid cooling to a standard 4U rackmount chassis. Instead of leaving thermal design to the integrator, InWin ships the chassis with a 360 mm all-in-one liquid cooler already mounted on the front radiator position, plumbed with 450 mm tubing and driven by a three-fan array that moves just under 94 CFM per fan.

Two AIO packages cover the current server and workstation socket landscape. IW-LSA36 targets Intel LGA4710 and LGA4677 boards at up to 350 W CPU TDP with a 4,500 RPM pump, while IW-LSC36 covers Intel LGA1851/1700/1200/20xx/115x and AMD AM5/AM4 with a 3,100 RPM pump. That makes the chassis equally usable for a Xeon 6 AI node and a Ryzen/AM5 edge inference box.

Compute expansion runs to eight full-height full-length PCIe slots, enough for multi-GPU AI training or inference configurations, and the chassis accepts either a 2000 W 1+1 CRPS 80 PLUS Platinum supply or a 2500 W ATX unit. Storage scales to five 3.5-inch drives or a four-plus-one 3.5/2.5-inch mix, with two optional 80 x 25 mm rear fans plus an 80 x 38 mm kit available for extra GPU-side airflow.

Key Benefits

Liquid cooling pre-installed — 360 mm AIO, no separate radiator procurement or mounting. Two socket packages cover Intel LGA4710/4677 server and AM5/LGA1851 mainstream platforms. Eight FHFL PCIe slots for multi-GPU AI acceleration. Flexible power — 2000 W 1+1 CRPS Platinum or 2500 W ATX. 3.5-inch storage scaling to five drives for local datasets.

Applications

Liquid-cooled AI training and inference nodes, enterprise edge AI servers, CPU-heavy inference hosts with one to two accelerators, quiet lab and office rack deployments, and integrator barebones where a factory-fitted AIO reduces assembly steps.
