Immersion Cooling ROI vs Air Cooling: Mining Economics Framework
A downside-aware framework to compare immersion cooling and air cooling using capex, uptime, maintenance, and power assumptions.
Decision Problem
Cooling decisions are often made with incomplete economics. ROI depends on full-lifecycle costs, not only immediate efficiency gains. This framework helps compare immersion and air setups under realistic conditions.
Model Inputs
- Capex: tanks, fluid systems, pumps, controls vs air-cooled infrastructure.
- Opex: energy overhead, maintenance labor, replacement cycles.
- Uptime: downtime risk and recovery time assumptions.
- Scaling friction: deployment complexity for additional hardware.
Scenario Method
- Build base case with conservative assumptions.
- Add downside case with higher maintenance and lower uptime.
- Stress test under higher difficulty and weaker BTC conditions.
- Select the model that survives downside, not only best-case ROI.
If your model omits maintenance complexity and recovery time, expected ROI is usually overstated.
