Reducing Bypass Airflow Is Essential for Eliminating Computer Room Hotspots

This pioneering study determined that high-heat densities and/or inadequate cooling capacity were not the underlying cause of hotspots. The highest percentage of hotspots was found in computer rooms with very light loads. Additionally, between 3.2 and 14.7 times more cooling capacity was running in those rooms than was required by the actual heat load. This white paper outlines counter-intuitive findings and relatively inexpensive solutions to recover wasted cooling capacity.
