In practice, cooling follows straightforward physics. To cool a system, you must deliver sufficient water/coolant at the appropriate temperature and pressure through the loop. If you want to increase the cooling capacity of a CDU, you increase flow rate while managing pressure, which in this case implies around a 2.0-2.5x flow increase, depending on how far outlet temperatures are actually pushed by operators.
Evidence
Nvidia has achieved this by optimizing the entire hydraulic path
