CPU is the central processing unit of a computer that is meant to execute all the circuitry instructions of a computer program. The input/output operations of a computer program, arithmetic, logic, and controlling tasks are all performed by the CPU.

According to Mark Galina: “ During normal operation, transistors inside a CPU convert electrical energy to thermal energy, and If an efficient path for that heat doesn’t exist, then the CPU will exceed its safe operating temperature.”

To deal with this issue, CPU cooler, and fans are designed so that the computer dissipates minimum heat and it works efficiently with a longer lifespan. These coolers provide a path for dissipated heat so that it does not exceed the safe operating temperature of a computer.
