Phone Farm Cooling and Power: Why Chassis Design Beats Open Racks at 100+ Nodes

Open racks with consumer phones look cheap until you count cable chaos, uneven airflow and USB power sag. Professional phone farm boxes integrate power distribution, cooling fans and fixed slot geometry. **Why chassis wins at 100+ nodes** - Predictable airflow path vs phones stacked on shelves - One power entry per box instead of 100 wall adapters - Labeled USB/Ethernet trees per chassis - Stackable footprint for warehouse or rack rows **Power planning** Motherboard boxes draw ~100W at 20 nodes; 32PCS chassis ~160W. Plan circuit load when running 10+ boxes continuously. **Cooling** Clean fan filters monthly in dusty sites. Leave 5–10 cm gap between stacked boxes.
