Notebook summer How to heat the effect is good?

Soon to the summer, the weather is gradually heating up, for the original cooling is not very good laptop, how to spend the 2012 years of the summer? For many friends notebook may be new to buy when the heat is still better, but with time lengthened, we will find that the heat dissipation may have been worse than before, Plus a lot of games like often play games, calorific value is bigger, then the notebook summer how to heat the better it (Thunder on the computer have influence?) The following computer network editor to talk about personal views.

Notebook cooling methods can generally be divided into hardware cooling and software cooling two categories, the former mainly for the notebook computer with a cooling fan, cooling base or cooling water cushion. This approach is done from the outside of the notebook computer, through the fan to speed up the heat distribution of the notebook computer or strengthen the laptop and other objects in the heat transfer to speed up the laptop heat distribution.

However, the use of notebook computers in high temperature environment, it is recommended to buy a cooling base or cooling water cushion. There are two types of heatsink base for the market, one is simply a simple base made of plastic or metal, on the bottom of the laptop, the foot of the base can make the back of the laptop a few centimeters higher, which can accelerate the airflow around the laptop, and the other is to install a base with a cooling fan, the structure is not complex , generally by the metal shell plus the built-in 2~4 fan composition (Figure 5), the fan power scheme has a laptop USB port and external power supply two, and some products also have the ability to extend the output of multiple USB ports. In addition to the heatsink base, the loose hot water mat is also a good heat dissipation tool. There are many brands and various sizes of the water cushion on the market, and the effect of the cooling on the computer is very obvious after the mat is placed on the bottom of the notebook computer. In general, the radiator base and cooling water cushion can get a good cooling effect, but some inconvenient to use, especially when the notebook computer placed on the water mat, notebook computer will produce displacement to affect the user's operation. In addition, the heatsink base and water cushion are required to purchase extra, increasing the user's overhead.

In many heating parts, the CPU is hot "giant", so people have developed a frequency reduction, using software to reduce the CPU heat cooling method. Intel uses a technology called SpeedStep from the PIII level CPU, which lowers the CPU's operating voltage and operating frequency, thereby reducing power consumption and calorific value. For example, a nominal frequency of 1.8GHz Pentium M CPU, in the battery optimization mode can be reduced to 600MHz to run (in the AC power mode can also be used to reduce the frequency of the software), the CPU's calorific value naturally will be significantly reduced. Reduce frequency to cool the shortcomings are also obvious, the CPU in the cooling will also greatly reduce the actual performance, the user's application will bring disadvantage, so in high load state is impossible to reduce the CPU temperature by reducing frequency. Cooling software is a monitoring CPU foreign instructions and has the highest priority of management software, when it found that the CPU does not have foreign instructions, let the CPU into the suspend mode, so that the CPU has a "sneak" time, the calorific value will then come down, and when there are foreign directives, it will wake the CPU, Make it resume processing work.

However, cooling software under Windows XP system more efficient, you can get a good cooling effect, and Windows XP below the system built-in idle instructions, so the cooling effect is not obvious, but for now, the minimum version of the system is XP bar, so this can be ignored.

About notebook Summer cooling method is mainly using the CPU to reduce frequency or to enhance the heat dissipation to achieve, but the author suggests or to strengthen the cooling better, at the expense of computer performance in exchange for lower calorific value is not our pursuit of results, if you like to reduce frequency that can also be through Baidu Search CPU frequency reduction software to adjust, But for those who do not want to buy the radiator base of friends, summer use of the computer can also use the fan to the author near the heat blown to achieve a certain cooling effect, interested friends may wish to refer to.
