Speccy, developed by Piriform Software, is a freeware utility software and runs under Microsoft Windows 11, Windows 10, Windows 8, Windows 7, Vista and XP for both IA-32 and x64 versions of these operating systems, [4] [5] which shows the user information about hardware and software of the computer.
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.
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]
CPU-Z is more comprehensive in virtually all areas compared to the tools provided in Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate. It also provides information on the system's GPU.
These monitoring systems are often used to keep track of system resources, such as CPU usage and frequency, or the amount of free RAM. They are also used to display items such as free space on one or more hard drives, the temperature of the CPU and other important components, [ 3 ] and networking information including the system IP address and ...
The dust buildup on this laptop CPU heatsink after three years of use has made the laptop unusable due to frequent thermal shutdowns. In operation, the temperature of a computer's components will rise until the heat transferred to the surroundings is equal to the heat produced by the component, that is, when thermal equilibrium is reached. For ...
Hence, once we know the thermal power to be dissipated (Pd), the maximum allowed case temperature (Tc) of the CPU and the maximum expected ambient temperature (Ta) of the air entering the cooling fans, we can determine the fundamental characteristics of the required Heat sink, i.e. its thermal resistance Rca, as:
