OCP PG25 cold-plate coolant guideline: keep the rise at 7.5–12 °C, typically 10 °C, which is about 1.25–2.0 L/min/kW (typical 1.5)
~1.25–2.0 L/min/kWrecommendation
| Value kind | recommendation — Recommendations are design guidance, not measured facts; validate them against the project boundary conditions. |

| Scope | OCP's OAI System Liquid Cooling Guidelines (3 March 2023 update, §1.3) recommend a 7.5–12 °C coolant-temperature rise for PG25 in OAI/OAM cold-plate systems, about 1.25–2.0 L/min per kW, with 10 °C and 1.5 L/min per kW as the typical design target. It is neither a facility-water delta-T nor a rack OEM's acceptance range; select the installed flow from the equipment schedule and approved fluid. |
