Inside a gaming case during gameplay. 360° photograph. A full tower case. Accessories shown include: a fan controller, a DVD burner, and a USB memory card reader.. Cases can come in many different sizes and shapes, which are usually determined by the form factor of the motherboard since it is physically the largest hardware component in most computers. Consequently, personal computer form ...
The system power consumption is a sum of the power ratings for all of the components of the computer system that draw on the power supply. Some graphics cards (especially multiple cards) and large groups of hard drives can place very heavy demands on the 12 V lines of the PSU, and for these loads, the PSU's 12 V rating is crucial.
Phase-change cooling is an extremely effective way to cool the processor. A vapor compression phase-change cooler is a unit that usually sits underneath the PC, with a tube leading to the processor. Inside the unit is a compressor of the same type as in an air conditioner. The compressor compresses a gas (or mixture of gases) which comes from ...
Most computers are designed to be more powerful than their cooling system, but their sustained operations cannot exceed the capacity of the cooling system. [32] While performance can be temporarily increased when the computer is not hot ( overclocking ), [ 33 ] in order to protect the hardware from excessive heat, the system will automatically ...
A modern consumer CPU made by Intel: An Intel Core i9-14900KF Inside a central processing unit: The integrated circuit of Intel's Xeon 3060, first manufactured in 2006. A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary processor in a given computer.
The components inside the case cannot dissipate heat efficiently if the surrounding air is too hot. Case fans may be placed as intake fans , drawing cooler outside air in through the front or bottom of the chassis (where it may also be drawn over the internal hard drive racks), or exhaust fans , expelling warm air through the top or rear.
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
Also chassis, cabinet, box, tower, enclosure, housing, system unit, or simply case. The enclosure that contains most of the components of a computer, usually excluding the display, keyboard, mouse, and various other peripherals. computer fan An active cooling system forcing airflow inside or around a computer case using a fan to cause air cooling.
