2. Computer fan - Wikipedia

   en.wikipedia.org/wiki/Computer_fan

   Axial fans may rotate at speeds of up to around 38,000 rpm for smaller sizes. [23] Fans may be controlled by sensors and circuits that reduce their speed when temperature is not high, leading to quieter operation, longer life, and lower power consumption than fixed-speed fans. Fan lifetimes are usually quoted under the assumption of running at ...

3. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   Cross-flow fans give airflow along the entire width of the fan; however, they are noisier than ordinary centrifugal fans. Cross-flow fans are often used in ductless air conditioners, air doors, in some types of laptop coolers, in automobile ventilation systems, and for cooling in medium-sized equipment such as photocopiers.

4. Computer fan control - Wikipedia

   en.wikipedia.org/wiki/Computer_fan_control

   Since they must move more air through the same area of space, fans will become more noisy. Fans installed in a PC case can produce noise levels of up to 70 dB. Since fan noise increases with the fifth power of the fan rotation speed, [2] reducing revolutions per minute (RPM) by a small amount potentially means a large reduction in fan noise ...

6. Electronics cooling - Wikipedia

   en.wikipedia.org/wiki/Electronics_cooling

   Electronics cooling encompasses thermal design, analysis and experimental characterization of electronic systems as a discrete discipline with the product creation process for an electronics product, or an electronics sub-system within a product (e.g. an engine control unit (ECU) for a car).

8. Heat sink - Wikipedia

   en.wikipedia.org/wiki/Heat_sink

   A heat sink (also commonly spelled heatsink, [1]) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature.
