Another method of reducing the fan speed [5] is by moving the 5 V wire in the classical Molex power connector in the place of the Ground wire going to the fan, thereby delivering +7 V (12 V − 5 V = 7 V) to the fan. However, this is a potentially risky method, because +5 V PSU line is intended to source current only, not sink it, so the PSU is ...
There are 12 fan speed settings to control from a remote, plus an auto-shutoff and a nine-hour timer. A simple, easy-to-read digital display on the base shows multiple functions.
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 this function with additional cooling components or connect a manual fan controller with knobs that set fans to different speeds. [1]
SpeedFan is a system monitor for Microsoft Windows that can read temperatures, voltages and fan speeds of computer components. [3] It can change computer fan speeds depending on the temperature of various components. [1] [4] The program can display system variables as charts and as an indicator in the system tray.
If you tend to do higher-speed running on a flat surface, incline ranges won't really matter. But if you're a power walker with a 3-4 mph range, Winge says to look for middling incline options ...
A pull-chain and variable-speed control are present. Such a fan has two speeds controlled by a pull-chain: high (full power, independent of the position of the variable-speed control), and "Vari-Lo" (speed determined by the position of the variable-speed control). In some cases, maximum speed on Vari-Lo setting is slower than high.

A High-volume low-speed fan. A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. [1] HVLS fans are generally ceiling fans although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed."
