The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.
However, not all software is capable of accessing these advanced configuration parameters provided by some chips, and it is very common that the generic software implements only the most basic interfacing with the chips, namely, an explicit setting for the duty cycle for each fan control setting, subsequently performing the duty cycle ...
Most modern ATX cases do however have a PSU mount in the bottom of the case with a filtered air vent directly beneath the PSU. Prefer cool intake air, avoid inhaling exhaust air (outside air above or near the exhausts). For example, a CPU cooling air duct at the back of a tower case would inhale warm air from a graphics card exhaust.
Voltage spikes, also known as surges, may be created by a rapid buildup or decay of a magnetic field, which may induce energy into the associated circuit. However voltage spikes can also have more mundane causes such as a fault in a transformer or higher-voltage (primary circuit) power wires falling onto lower-voltage (secondary circuit) power ...
The CPU core voltage (V CORE) is the power supply voltage supplied to the processing cores of CPU (which is a digital circuit), GPU, or any other device with a processing core. The amount of power a CPU uses, and thus the amount of heat it dissipates, is the product of this voltage and the current it draws.
Here’s what garden and patio plants you can save for next spring. As the temperatures start to drop and sweater weather arrives, you may start to look sadly at your beautiful, lush garden plants.
At one point or another, we’ve all experienced the unexpected, intense pain of a muscle cramp. Here's how to start feeling better.
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. In applications where the computer is often heavily loaded, such as scientific computing, performance per watt (how much computing the CPU does per unit of energy) becomes ...
