👉 The PCS (PC Fluid System) is a critical component in many PCs, especially older or custom builds, designed to manage and circulate the liquid coolant that absorbs heat from the CPU and other high-heat components. It typically consists of a coolant reservoir, a pump, and a radiator with a heat exchanger. The PCS ensures efficient heat transfer by circulating the coolant through the system, absorbing heat from the CPU, and dissipating it into the air via the radiator. This process maintains optimal operating temperatures, preventing thermal throttling and ensuring reliable performance.
