2. Computer fan control - Wikipedia

   en.wikipedia.org/wiki/Computer_fan_control

   The voltage a computer cooling fan receives is defined by the difference between the voltage wire (+12 V) and the ground wire (+0 V). By connecting one or both wires to a different voltage, the voltage the fan receives will be different from the default 12 V the fan was designed for.

3. Computer fan - Wikipedia

   en.wikipedia.org/wiki/Computer_fan

   Fans attached to components are usually used in combination with a heat sink to increase the area of heated surface in contact with the air, thereby improving the efficiency of cooling. Fan control is not always an automatic process. A computer's BIOS can control the speed of the built-in fan system for the computer. A user can even supplement ...

4. Power supply unit (computer) - Wikipedia

   en.wikipedia.org/wiki/Power_supply_unit_(computer)

   The +12 V supply was used for computer fan motors, disk drive motors and serial interfaces (which also used the −12 V supply). A further use of the 12 V came with the sound cards, using linear chip audio power amplifiers, sometimes filtered by a 9 V linear regulator on the card to cut the noise of the motors.

   Fan speed can also be reduced more crudely by plugging them into the power supply's 5-volt line instead of the 12-volt line (or between the two for a potential difference of 7 volts, although this cripples the fan's speed sensing). [11] Most fans will run at 5 volts once they are spinning, but may not start reliably at less than 7 V.
