In this discussion, we have the chance to sit down with Castrol to explore the critical topic of data centre cooling efficiency. By examining the computing hardware trends and efficiency concerns, we open the floor to new methods for assessing the cooling performance of data centres. By discussing different thermal management systems, including air and liquid cooling systems, fluid types, and engineering approaches, we will learn how to make data centres more efficient and able to demonstrate a fully integrated, optimized and scalable solution suitable for the data centres.
