Cooling problems in data centers rarely start with alarms. They usually appear first as small warning signs—uneven rack temperatures, rising fan speeds, unexplained hot spots, or cooling units working harder than expected. This guide outlines ten common indicators that airflow or cooling performance may be limited, helping operators recognize hidden thermal issues before they impact uptime.

A brand-new facility with recurring efficiency problems. Assessment identified airflow leaks introduced during construction. Fixed before reaching full operational load.

Discover the four delta-Ts that define data center cooling efficiency and how measuring all of them can cut energy costs by up to 40%. Learn how Purkay Labs’ AUDIT-BUDDY delivers fast, rack-level thermal insights without permanent infrastructure.

In our latest article, we break down the four essential Delta-Ts, what they reveal about cooling performance, and why periodic measurement is the only way to ensure your facility is operating as designed. Learn how Delta-T monitoring helps prevent inefficiencies, optimize cooling, and reduce operational costs.

Learn how monitoring and improving Server Delta-T can enhance cooling efficiency, reduce energy waste, and prevent equipment failures in data centers.

This article explores how measuring and optimizing Delta-T across CRAC and CRAH units can improve data center cooling efficiency, reduce energy costs, and enhance airflow management.

Learn key strategies for forecasting and managing cooling costs in data centers, including how to account for seasonal changes, energy price fluctuations, operational growth, and the benefits of investing in energy-efficient technologies. Discover smart budgeting practices that can help optimize cooling expenses while maintaining operational efficiency.
