--- title: Cooling Systems --- <del> Your computer contains many parts that generate heat. Heat can cause premature failure and erratic behaviors. The more you overclock the graphics or the CPU, the hotter the computer will run. Cooling systems assure that your computer is stable and you extend the life of your investment. </del> <ins> Your computer contains many parts that generate heat.

Most cases come with at least one fan. This is the minimum configuration. For best results, there be at least two fans in the case. One is as an intake to draw in cold air while the other is an exhaust to expel hot air. There are many different types of fans and configurations. Cable management also plays a huge part in cooling the system. Bad cable management and tangled wires disrupt airflow and cause dust to accumulate inside the case. </del> <ins> Case cooling can be a combination of a well ventilated case and the use of fans to circulate air within the case.

The two most common are coolers for CPU's and graphics cards. There are generally two types of component cooling systems, active and passive. <del> * Passive Systems - Usually consist of a heat sink or a heat conductive metal attached to the component. Passive cooling works by providing a larger surface to adsorb and dissipate the heat. </del> <ins> * Passive Systems - Usually consist of a heat sink or a heat conductive metal attached to the component. Passive cooling works by providing a larger surface to absorb and dissipate the heat. </ins> * Active Systems - Add a fan to the heat sink and you are actively removing heat. The cooling fan can be dynamically adjusted to the load of the CPU or graphics card on most motherboards. * Liquid Cooling - High performance computers can benefit from a liquid cooled system. These types of systems circulate a liquid between the hot components and a cooling radiator.

* Case Covers - Contrary to what you read on the internet, keeping the case covers on the computer aids cooling. Absence of the case covers disrupts air flow and can actually increase the heat inside the case. Room ventilation - Locate the computer where it is neutral to the rooms environmental registers. Keep the computer away from room heaters or vents at all times. * Room placement - Locate the computer away from windows or areas of strong sunlight exposure. Placement in closets can also provide challenges to cooling. <del> * Placement next to other computers - Locating the computer away from other equipment allows air to flow in and out of the computer. Placement close to other equipment can constrict air flow and increase heat. </del> <ins> * Placement next to walls and other computers - Locating the computer away from other equipment allows cool, clean, air to flow in and out of the computer. Placement close to other equipment can constrict air flow and increase heat. Placement next to a wall may also lead to the exhaust ports being completely blocked off and consequently increase heat. </ins> [Wikipedia - Article on computer cooling](https://en.wikipedia.org/wiki/Computer_cooling)
