PG25 (25% propylene glycol) is one of the most popular coolant solutions for GPU and data center cooling. However, due to evolving performance requirements and increasing concerns about environmental sustainability, it is becoming unlikely that PG25 will meet the needs of future technology. Because coolant chemistry has a direct impact on the design and optimization of heat sinks and related thermal management components, Diabatix partnered with the ZITREC® EC team from Arteco to explore the relation and impact of coolant technology on cooling designs.
