Vol.005 - Not Ready to Move to Liquid Cooling? How EVAC Sustains Air Cooling in High-Density Data Centers
When Conventional Air Cooling Reaches Its Limit: How EVAC Opens Up New Thermal Headroom for High-Power Platforms In thermal design, heat is never merely a secondary concern; it is a critical factor that directly affects system performance, stability, and reliability. Within a conventional thermal architecture, TIM materials help eliminate air gaps at the interface, heat pipes transfer heat, heatsinks increase the available area for heat dissipation, and fans carry heat away from the system. This approach has long supported the thermal requirements of servers and other high-performance equipment. However, as AI computing continues to drive demand for greater processing capability, chip power consumption has risen accordingly, and conventional air-cooling architectures are gradually approaching their practical limits. Why Has EVAC Gained Attention? Since 2019, platform TDP levels from Intel, AMD, and later NVIDIA have continued to increase. In conventional thermal designs...
