If you're still relying on traditional air cooling, this guide will show you why it's time to rethink your setup.
Immersion cooling is a liquid-based thermal management system where electronic components like ASIC miners or GPUs are submerged directly in dielectric fluid, a thermally conductive, non-conductive oil that efficiently pulls heat away from the components.
Instead of forcing air over hot hardware using fans, immersion cooling dissipates heat by circulating liquid, either through single-phase or two-phase cooling systems:
Single-phase immersion: The coolant absorbs heat but remains in a liquid state.
Two-phase immersion: The coolant evaporates into gas, carries heat away, and condenses back into liquid—used in high-performance setups.
| Feature | Air Cooling | Immersion Cooling |
| Efficiency (PUE) | ~1.3 to 2.0 | As low as 1.02–1.05 |
| Noise | 70–90 dB from fans | <30 dB, near silent operation |
| Hardware Lifespan | Reduced due to thermal cycling & dust | Extended by 1.5–2x with stable temperature and protection |
| Energy Use | High (25–40% of total power just for cooling) | Reduced by up to 30%, less reliance on HVAC |
| Density & Scalability | Low; requires airflow spacing | High; compact, vertical, modular configurations |
| Environmental Resistance | Poor, sensitive to humidity, dust, etc. | Excellent, sealed system protects from contaminants |
| Maintenance | High; fan failure, filter replacements | Low; no fans, no filters, less physical contact |
| Overclocking Potential | Limited due to heat constraints | High, lower and stable temps allow safe overclocking |
Energy efficiency is crucial to mining profitability. Traditional air-cooled farms waste a large portion of power just moving hot air. With immersion, cooling-related energy drops by 20–30%, reducing your Power Usage Effectiveness (PUE) to near-perfect levels.
Case Study: A 1 MW mining facility reduced total energy use by 180,000 kWh/month after switching to immersion, translating into $18,000 in monthly savings at $0.10/kWh.
Immersion keeps chips cooler and more thermally stable, unlocking safe overclocking. With the right tuning, miners report 10–30% hashrate increases while staying within safe temperature ranges.
Example: WhatsMiner M50s overclocked from 130 TH/s to 150 TH/s in a single-phase immersion setup without overheating.
Forget the roar of fan farms, immersion systems eliminate almost all moving parts, including loud fans and blowers. The result is whisper-quiet mining, ideal for both residential setups and urban facilities.
No fans to replace. No filters to clean. No overheating surprises. Many immersion setups run for years without major maintenance, especially when using high-quality fluids.
Air-cooled farms need space for airflow. Immersion setups allow vertical stacking or tank-based compact designs, ideal for high-density installations and mobile containers.
Immersion cooling thrives in harsh environments, dusty, humid, hot, or cold. It even works well in off-grid setups powered by renewables.
Use Case: In the Middle East and North Africa (MENA), immersion allows mining in 45°C+ conditions without performance loss.
Immersion cooling allows waste heat recovery for industrial, agricultural, or residential applications. You can redirect this heat to warm greenhouses, water, or buildings, improving sustainability.
Start with one tank, then scale. Many manufacturers offer plug-and-play immersion kits for small farms and large data centers alike.
Popular Models: FogHashing C1, DCX MiniTank, LiquidStack S-Series
Though the upfront cost is higher (often 1.5–2x that of air cooling), the operational savings, reduced failure rates, and higher throughput deliver significantly better ROI within 6–12 months.
Cost Breakdown (Typical 1 MW Farm)
| Component | Air Cooling | Immersion Cooling |
| Initial Hardware Setup | $850,000 | $900,000 |
| Cooling Infrastructure | $200,000 (fans + HVAC) | $280,000 (tanks + fluid) |
| Monthly Cooling Energy Use | ~$18,000 | ~$9,000 |
| Annual Maintenance | $20,000 | $5,000 |
| Payback Period | N/A | ~6–10 months |
From major mining companies to independent miners, immersion cooling is no longer a luxury, it’s a strategic advantage. As heat loads increase with newer ASICs and regulatory pressure mounts for energy efficiency, immersion will become the industry norm.
Even Bitmain and MicroBT now certify their miners for immersion use, reflecting a growing ecosystem of compatible hardware and support.
If you're serious about maximizing profitability, reliability, and sustainability in crypto mining, immersion cooling is no longer optional, it’s essential.
