. In winter, if you are holding a laptop and surfing the Internet, you will feel warm without turning on the heating. But this is not a good thing, because the computer is more delicate than the person, if the temperature is too high, it is likely to hang directly. Therefore, everyone should keep warm for themselves in the winter, cool down the computer, cool down in the summer, and cool down the computer. In the past, cooling the computer first thought of replacing or renovating the cooling device. If you don't want to do this, you can try to solve it from the software under Win7 system.
Users of Win7 computers should be familiar with the power plan in the control panel. The power plan in Win7 has many improvements compared with XP. It provides three power modes and works in different modes. The working frequency of the computer hardware will change, which will affect the power consumption, and indirectly achieve the purpose of cooling. The three power plans that come with Win7 are:
1. The minimum power dissipation of the power-saving mode is the lowest
In the default setting of the energy-saving mode, the power plan of the graphics card is "maximum battery life. The processor cooling mode is “passive”, the minimum processor state is “0%”, the maximum processor state is “100%”; the screen brightness when using the battery is 40%, and the power is 100% after the power is turned on. The energy-saving mode is more suitable for mobile office use. All hardware works in the lowest power consumption state, which is the mode with the lowest power consumption, so the heat dissipation is the lowest.
2. balanced mode power depending on usage, the amount of heat at higher
balance default setting mode, the graphics card power plan is "balanced"; ON The power supply after-processor cooling mode is “active”, the minimum processor state is “5%”, the maximum processor state is “100%”; the screen brightness when using the battery is 40%, and the power is 100% after the power is turned on. That is to say, in balanced mode, full performance is provided only when the computer is active, and when it is inactive for a period of time, it automatically enters the power saving state. For most people, this is the most reasonable power plan.
3. High-performance mode consumes the most power, and the computer directly turns into a heat sink
In the default setting of high-performance mode, the power supply plan of the graphics card is "highest performance"; The heat dissipation method is “active”, the minimum processor state is “100%”, the maximum processor state is “100%”; the screen brightness when using the battery is 100%, and the power is 100% after the power is turned on. In high-performance mode, all hardware is in optimal working condition, so it consumes more power and the heat dissipation naturally increases.
A few things you must know to cool your computer
For desktop computers, there are only a few things to cool down in the hot weather in summer. method:
1, reduced CPU, GPU frequency;
2, increase the heat dissipation hardware, such as replacing a better thermal conductivity heat sink, more fan air volume;
3, improve ventilation conditions, such as cleaning the dust deposited on the heat sink, open the cover to make the temperature easier to emit.
For notebooks, in addition to increasing cooling method such hardware base outside, want to cool the books will be achieved by reducing the CPU, GPU usage.
