Data center cooling is often described as “keeping the room cold,” but the real goal is much simpler: move heat away from servers efficiently. This guide explains how airflow actually works inside a data center, how Delta-T reveals cooling performance, and why airflow distribution often matters more than cooling capacity. Understanding the path from supply air to server inlet, exhaust, and return gives operators the foundation needed to diagnose cooling problems before they impact uptime.

This Thanksgiving, Purkay Labs gives thanks for the data center systems and people that keep things cool, efficient, and running 24/7.

This Halloween, Purkay Labs busts five cooling and airflow myths that still haunt data centers — and shows how to keep your facility truly chill.
