Terms & Concepts
  • J/TH: Joules per terahash, a mining efficiency metric showing how much energy hardware uses to perform one trillion hash calculations.
  • Hydro-cooled: A cooling design that uses liquid-based heat removal systems for mining hardware, typically to manage higher-performance operations more effectively.
  • Air-cooled: A mining hardware cooling method that uses airflow and fans to dissipate heat during operation.
