Context Before

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.

Evidence

If you want to increase the cooling capacity of a CDU, you increase flow rate

Context After

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.

② Atomic Claim

若要提高 CDU 的 cooling capacity，就需要提高 flow rate。
