Air cooling
Ask about ventilation, noise, ambient temperature and continuous electrical capacity. Match the facility to the exact model and deployment size.
Hydro cooling
Ask the provider to confirm water-circuit requirements, compatible connectors, rack format and the way cooling electricity is billed. Do not assume two hydro models use the same installation.
Immersion cooling
Confirm fluid and equipment compatibility, any required modifications, servicing procedures and warranty implications with the manufacturer and host.
Compare the full hosting bill
Request the electricity rate and currency, cooling overhead, management, installation, deposits and minimum term in writing. Include these costs in the calculator rather than comparing advertised energy rates alone.
