Airflow inside a server is meticulously designed to ensure that the hardware operates within safe temperature ranges, which is critical for maintaining performance and preventing overheating. Cool air is typically drawn in from the front of the server through intake fans, passes over the heat-generating components such as the CPU, memory, and hard drives, and is then expelled as hot air through exhaust fans at the back of the server. This controlled airflow ensures that each component receives the cooling it needs. Effective airflow management within the server, complemented by data centre solutions like blanking panels, helps maintain optimal operating conditions, extends the lifespan of the equipment, and reduces the overall energy required for cooling.

Cold aisle containment is a highly effective strategy for improving the efficiency and performance of data centre cooling systems. This approach involves physically separating the cold air used for cooling servers from the hot exhaust air, typically by enclosing the cold aisle where the server fronts are located. By preventing the mixing of hot and cold air, cold aisle containment ensures that cooling is more targeted and efficient, reducing energy consumption and lowering operational costs. Products designed for cold aisle containment, such as doors, ceiling panels, and blanking panels, help maintain a stable, cool environment within the aisle, allowing data centres to operate more efficiently and sustainably. This solution is particularly valuable in high-density environments where cooling demands are significant.
