Typical Real-Life Server Example: The IT nodes simulated here, with an IT power of approximately 8.46 kW, are representative of modern high-performance servers.
These are often multi-GPU systems (e.g., NVIDIA DGX-like servers or similar) designed for AI/ML training or HPC. The dominant "IT Component A1" (5.2 kW) likely represents such a GPU subsystem.
The remaining power accounts for powerful CPUs, RAM, networking, and storage. Such high power density makes them prime candidates for direct liquid cooling.

The "Baseline Fan Power (DC)" of 168.0 kW assumes all IT components are air-cooled. This is derived from: 200 nodes × 840W/node (fans @25°C SAT) = 168.0 kW.
