  2. Idle (CPU) - Wikipedia

    en.wikipedia.org/wiki/Idle_(CPU)

    Idle is a state that a computer processor is in when it is not being used by any program. Every program or task that runs on a computer system occupies a certain amount of processing time on the CPU. If the CPU has completed all tasks it is idle. Modern processors use idle time to save power.

  3. Computer fan control - Wikipedia

    en.wikipedia.org/wiki/Computer_fan_control

    Different software is used by different motherboards. There are also third-party programs that work on a variety of motherboards and allow wide customization of fan behavior depending on temperature readings from the motherboard, CPU, and GPU sensors, as well as allowing manual control. Two such programs are SpeedFan [11] and Argus Monitor. [12]

  4. Dynamic frequency scaling - Wikipedia

    en.wikipedia.org/wiki/Dynamic_frequency_scaling

    ACPI 1.0 (1996) defines a way for a CPU to go to idle "C states", but defines no frequency-scaling system.. ACPI 2.0 (2000) introduces a system of P states (power-performance states) that a processor can use to communicate its possible frequency–power settings to the OS.

  5. Computer cooling - Wikipedia

    en.wikipedia.org/wiki/Computer_cooling

    A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.

  6. System Idle Process - Wikipedia

    en.wikipedia.org/wiki/System_Idle_Process

    In Windows NT operating systems, the System Idle Process contains one or more kernel threads which run when no other runnable thread can be scheduled on a CPU. In a multiprocessor system, there is one idle thread associated with each CPU core. For a system with hyperthreading enabled, there is an idle thread for each logical processor.

    CPU Idle: 0x05: Requests system suspend. 0) Clock halted until timer tick interrupt. 1) Slow clock [1] CPU Busy: 0x06: Driver tells system APM to restore clock speed of the CPU. Set Power State: 0x07: Set system or device into Suspend/Standby/Off state. Enable/Disable Power Management: 0x08: Restore APM BIOS Power-On Defaults: 0x09: Get Power ...

  8. Windows System Assessment Tool - Wikipedia

    en.wikipedia.org/wiki/Windows_System_Assessment_Tool

    CPU Performance; Memory Performance; Disk Performance (includes devices such as Solid-state drives) While running, the tests show only a progress bar and a "working" background animation. Aero Glass is deactivated on Windows Vista and Windows 7 during testing so the tool can properly assess the graphics card and CPU.

  9. Processor power dissipation - Wikipedia

    en.wikipedia.org/wiki/Processor_power_dissipation

    In many applications, the CPU and other components are idle much of the time, so idle power contributes significantly to overall system power usage. When the CPU uses power management features to reduce energy use, other components, such as the motherboard and chipset, take up a larger proportion of the computer's energy.
