SpanFeed indicates the processor temperature, fan speed, temperature of the hard disk, the CPU load, and so on. It is important to know the temperature that reaches the CPU when the PC is required, for example when playing, to be able to regulate and normalize it thanks to the action of this tool.
A fundamental thing that can be achieved is to regulate the speed of the fan (or fans) by a calculation depending on the temperature and other factors. In this way, it is possible to achieve a decrease in the annoying noise caused by the fan, as well as to decrease the consumption and lower the temperature.
