The passage around this formula

…requires impractical airflow velocities and fan power. The heat-removal budget for a cold plate loop follows directly from the sensible-heat relation: $\dot{Q} = \dot{m}\, c_p\, \Delta T$. where $\dot{Q}$ is the heat to be removed (watts), $\dot{m}$ is the coolant mass flow rate, $c_p$ is its specific heat, and $\Delta$ T is the temperature rise the coolant is allowed across the cold plate. This is the one relationship every cooling-loop sizing decision in this article reduces to: a facility either raises $\dot{m}$ (bigger pumps, more flow,…
