Cooling
Heat rejection
A dry cooler can only bring water down to a few degrees above outdoor air. Adiabatic pads and cooling towers use water to get below that limit.

the topic source was opened on 2026-09-18; it discusses adiabatic cooling for data centres but carries no noise figure and no tower-versus-dry-cooler power comparison, so the two figures that had been resting on it were removed
