A computer fan is any fan inside, or attached to, a computer case used for active cooling, and may refer to fans that draw cooler air into the case from the outside, expel warm air from inside, or move air across a heat sink to cool a particular component.
As processors, graphics cards, RAM and other components in computers have increased in speed and power consumption, the amount of heat produced by these components as a side-effect of normal operation has also increased. These components need to be kept within a specified temperature range to prevent overheating, instability, malfunction and damage leading to a shortened component lifespan.
While in earlier personal computers it was possible to cool most components using natural convection (passive cooling), many modern components require more effective active cooling. To cool these components, fans are used to move heated air away from the components and draw cooler air over them. Fans attached to components are usually used in combination with a heatsink to increase the area of heated surface in contact with the air, thereby improving the efficiency of cooling.

If you have a spare computer fan, 9V battery and a piece of duct tape you can make a portable fan in less than minute. Extremely useful for cooling during during hot days, long trips etc. User tips: Marlon Pritchard: you can use pillers [or knife - Krzysiu] to strip wires and avoid smoke 1991fordexplorer: 12V battery from RC car will be even better http://krzysiu.net/misc/how_to_make_a_portable_fan_using_a_computer_fan_and_a_battery Music: Brian Boyko - Folk Song (CC-0: http://creativecommons.org/publicdomain/zero/1.0/)
In this project, Jason Poel Smith combines 16 PC cooling fans into a large 12V box fan. The result is a fan that is quiet and thin enough to store almost anywhere. It is also a great example of reusing and repurposing electronic waste. View the full project: http://makezine.com/projects/pc-box-fan/
In This Video I Show you how to power a Computer Fan With a USB cable. This can be used for a cooling device or you can use it as a project for any idea you might have. What you Will Need: 1. Any Computer Fan 2. A USB Cable 3. Computer To Connect USB/ USB Wall Charger This is a easy project for you to do at home or anywhere Check Out My New Website: http://t2gi.blogspot.com/

It is also quite useful as a fume extractor while soldering. Music: Ecstatic Wave by Jens Kiilstofte https://machinimasound.com/music You want to support my videos?

How a computer fan spins using magnets If you see these on the net, they are fake, this video shows how the fan spins using 2 hidden batteries and a reed switch. The lamp being illuminated is also a trick, the fan does NOT provide any power to light a lamp or even spin in its own. Do not get caught in free energy scams!

I intend to make a small ROV out of scrap parts to test a few ideas I have. The first thing I want to know is if I could use a computer fan for propulsion or maneuvering. Do they even work underwater? This video has the answer.
