Cryogenic cooling

Definition

Cryogenic cooling refers to the process of lowering temperatures to extremely low levels, typically below -150°C (-238°F), using liquefied gases like helium or nitrogen. This method is essential for efficiently managing heat in advanced computing systems, particularly at exascale levels, as it helps reduce thermal noise and enhances performance by improving the reliability and speed of electronic components.
