Illustration of the airflow of the cooling air in a computer case during computer cooling. Desktop computers typically use one or more fans for cooling. While almost all desktop power supplies have at least one built-in fan, power supplies should never draw heated air from within the case, as this results in higher PSU operating temperatures ...
Full-tower computer cases may contain multiple cooling fans. At the top of the case is a fan controller. Fan control is the management of the rotational speed of an electric fan. In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they ...
[citation needed] Most of the time memory modules, located close to CPU will receive enough of the air flow from the case or CPU fan, even if the air from CPU fan and radiator is warm. If the main CPU is water cooled, this small amount of airflow might be missing, and additional care about some airflow in a case or a dedicated memory cooling is ...
A balanced or neutral airflow is the most efficient, although a slightly positive airflow can result in less dust build up if filtered properly Heat pipes A heat pipe is a heat transfer device that uses evaporation and condensation of a two-phase "working fluid" or coolant to transport large quantities of heat with a very small difference in ...

The popular 2N3055 power transistor in a TO-3 case has an internal thermal resistance from junction to case of 1.52 °C/W. [4] The contact between the device case and heat sink may have a thermal resistance between 0.5 and 1.7 °C/W, depending on the case size and use of grease or insulating mica washer. [3]
The air flow capacities of the fans are compared and connected in same outlet or same inlet conditions. This causes noise , specifically referred to as Beating in case of fans in parallel. To avoid beating use is made of differing inlet conditions, differences in rotational speeds of the fans , etc.
