Playground
Liquid cooling, learned by moving numbers instead of reading paragraphs. Start with the loop below — then take a tool apart.
The loop, live
Servers → manifold → CDU → heat out. Drag anything; the flow speed, the heat arrows and the capacity verdict all follow.
flow 54 L/min (ΔT 8 °C) · liquid 30.0 kW · air 10.0 kW — same models as the flow, capture and derating pages
The tools
Rack builderPick real server platforms (GB200 NVL72, HGX B200/H100, MI300X) and real cooling products (Vertiv CDU 70, STULZ, Asetek L2L) — derated capacity, flow and facility needs settle live, every selection sourced→Derating simulatorCapacity vs room temperature as a draggable curve — exactly what 25 °C → 35 °C does to an L2A CDU→Room load calculatorCabinet kW, installed AC, existing heat — live verdict on whether the room can host the cabinet→
Why a playground
Models are first-order and anchored to published data where it exists (e.g. Vertiv XDU070 curves); they illustrate physics, not replace vendor engineering. If a tool says your room doesn't fit — that's the point: find out here, for free, before anyone ships anything.
