Description
Technical Field
The invention relates to a computer fan control system.
Background
With the progress of technology, electronic products are developed toward being light, thin, small and small. On the other hand, when the electronic product is operated, heat generation is necessarily accompanied. Without a proper heat dissipation system, the electronic product is damaged due to the temperature rise.
For the current cpu, the Thermal Design Power (TDP) set by the manufacturer is usually used as the basis for controlling the heat dissipation fan. However, with the conventional dynamic over-clocking mechanism, although the performance of the cpu can be effectively improved, the cpu is overheated due to the instant power increase exceeding the designed power of the heat sink. However, the fan system in the prior art may not be able to immediately and effectively suppress the heat energy in this situation, so the cpu will automatically start the frequency reduction mechanism to prevent the cpu from being burned down. Thus, there is no way to achieve the over-clocking purpose.
Therefore, in the prior art, the cpu is usually cooled down more quickly by increasing the fan speed during standby or replacing the cooling fan with better cooling performance. This, however, costs additional manufacturing costs.
Therefore, there is a need for a new computer fan control system to solve the deficiencies of the prior art.

As a specific embodiment, the current detecting module includes an analog-to-digital converter electrically connected to the voltage follower for converting the voltage difference signal into a digital voltage difference signal and transmitting the digital voltage difference signal to the second determining module, so that the second determining module can obtain the current value.
