  2. Heat sink - Wikipedia

    en.wikipedia.org/wiki/Heat_sink

    A heat sink is not a device with the "magical ability to absorb heat like a sponge and send it off to a parallel universe". [2] Natural convection requires free flow of air over the heat sink. If fins are not aligned vertically, or if fins are too close together to allow sufficient air flow between them, the efficiency of the heat sink will ...

  3. Computer cooling - Wikipedia

    en.wikipedia.org/wiki/Computer_cooling

    Fans are used when natural convection is insufficient to remove heat. Fans may be fitted to the computer case or attached to CPUs, GPUs, chipsets, power supply units (PSUs), hard drives, or as cards plugged into an expansion slot. Common fan sizes include 40, 60, 80, 92, 120, and 140 mm. 200, 230, 250 and 300 mm fans are sometimes used in high ...

  4. Computer fan control - Wikipedia

    en.wikipedia.org/wiki/Computer_fan_control

    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 ...

  6. Computer fan - Wikipedia

    en.wikipedia.org/wiki/Computer_fan

    A small blower fan is used to direct air across a laptop computer's CPU cooler. A case fan may be mounted on a radiator attached to the case, simultaneously operating to cool a liquid cooling device's working fluid and to ventilate the case. In laptops, a single blower fan often cools a heat sink connected to both CPU and GPU using heat pipes.

  7. Fan coil unit - Wikipedia

    en.wikipedia.org/wiki/Fan_coil_unit

    These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.

  8. Laptop cooler - Wikipedia

    en.wikipedia.org/wiki/Laptop_cooler

    An active laptop cooler. A laptop/notebook cooler, cooling pad, cooler pad or chill mat is an accessory for laptop computers intended to reduce their operating temperature when the laptop is unable to sufficiently cool itself. Laptop coolers are intended to protect both the laptop from overheating and the user from suffering heat related ...

  9. Centrifugal fan - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_fan

    A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).
