| Cooling | Where heat goes first |
|---|---|
| Immersion | Electronics sit in a dielectric liquid bath. |
| Hydro | Coolant flows through cold plates attached to the hardware. |
| Air | Fan-driven air flows across heat sinks. |
Follow the heat from chip to outdoors
In a typical single-phase immersion system, the fluid picks up heat in the tank. The system moves the warm fluid to a cooler or heat exchanger. The cooled liquid flows back to the tank. Some sites use a separate facility loop to carry heat outdoors. In a two-phase system, fluid boils at the hot surfaces and condenses back to liquid at a cooled surface.
Compare power at the same boundary
The miner’s J/TH measures energy per unit of hashing work. A site can also draw power for pumps and heat rejection. In this example, 100 kW for miners and 8 kW for cooling equipment make 108 kW at those meters. The cooling load is 8% of miner power. At constant load for 24 hours, those two loads consume 2,592 kWh. Ask which meter the tariff uses and whether cooling power is included or billed separately.
- Check the cooling type on every offer. The marketplace cards can show any cooling type. The named S19 XP+ Hydro example uses cold plates.
Check the actual hosting configuration
Start with the exact model and the cooling method declared on the listing. For an immersion quote, ask which hardware and fluid the host supports, how it handles maintenance, and which loads are covered by the tariff. Compare the price and delivered hashrate on the same basis. The S19 XP+ Hydro catalog below shows a live cold-plate option so you can see how this distinction appears in a real listing.
- Record the miner model, cooling type and tariff.
- Ask what the operator measures and bills.
- Check service and coverage terms for that exact configuration.
