Dell R650/R6525/R660/R6625 Very High Performance Fan

Very high performance fans may be required depending on the exact server model and hardware configuration, including higher-TDP processors, dense NVMe or EDSFF storage layouts, rear-drive configurations, GPU or accelerator support, high-density memory, and other components that increase system heat output. Dell thermal guidance for these systems ties fan requirements to CPU TDP, drive/backplane layout, rear storage, memory configuration, shrouds, and expansion hardware, so fan type should be matched to the server’s full configuration. Mixing standard, high performance silver, and high performance gold fan types is not supported on platforms where multiple fan classes are used.
