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 ...
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.

The PS/2 interface provides no restriction on key rollover, although USB keyboards have no such restriction either, unless operated in BOOT mode, which is the exception. To free USB ports for other uses like removable USB devices. Some USB keyboards may not be able to operate the BIOS on certain motherboards due to driver issues or lack of ...
In November 2007, HP released a BIOS update covering a wide range of laptops with the intent to speed up the computer fan and have it run constantly while the computer was on or off [154] to prevent the overheating of defective Nvidia graphics processing units (GPUs) that had been shipped to many of the original equipment manufacturers ...
Enhanced SpeedStep is a series of dynamic frequency scaling technologies (codenamed Geyserville [2] and including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel's microprocessors that allow the clock speed of the processor to be dynamically changed (to different P-states) by software.
