Heat sinkA component designed to lower the temperature of an electronic device by dissipating heat into the surrounding air. A heat sink without a fan is called a passive heat sink; a heat sink with a fan is called an active heat sink.Heat sinks are generally made of an aluminum alloy and often have fins.

Central Processing
UnitThe central processing unit (CPU) of a computer is a piece of hardware that carries out the instructions of a computer program. It performs the basic arithmetical, logical, and input/output operations of a computer system. The CPU is like the brains of the computer - every instruction, no matter how simple, has to go through the CPU.
