Just as every computer needs a processor, every processor needs a cooling system. Without one, the significant heat generated by the processor will overheat the system. As time has advanced, this heating issue has only become more critical, thus necessitating the advent of more effective cooling solutions. Microgaps, which pass coolant through, as the name suggests, a microscale gap, are uniquely suited to meet the ever-increasing cooling demands of modern processors. Moreover, they are capable of doing so in a compact and reliable manner.
