Effectiveness of Rack-Level Fans—Part II: Control Strategies and System Redundancy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fan efficiency is known to increase with size. In part I of this study, savings in server fan power on the order of 50% were reported by replacing server-enclosed 60 mm fans with a rear-mounted wall of larger fans (80 mm ...
Effectiveness of Rack-Level Fans—Part I: Energy Savings Through Consolidation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In general, smaller fans operate at lower efficiencies than larger fans of proportional linear dimensions. In this work, the applicability of replacing smaller, 60 mm baseline fans from within the chassis of web servers ...
