Diy Family Of Yourself As Notebook Cooling

We all know, the general notebook computer components in addition to fever CPU, hard drives and memory, there are display tubes, but the greatest source of heat is still CPU.

Books of the CPU cooling structure increases mainly aluminum heat exhaust fan means, of course, the aluminum plate may contain embedded copper heat pipe heat medium is used to speed up the CPU heat out of the speed of the aluminum The following is also fitted with a small exhaust fan, the aluminum hot air blowing around. In addition, most notebook computers also use shell or aluminum chassis with a keyboard as an auxiliary cooling means.

Notebook cooling control theory like this: through the temperature sensor to monitor CPU temperature, when the temperature reaches a critical value, the cooling fan started, one-way through the thermal conductivity of aluminum cavity, the hot air blowing through the mandatory circulating air, the temperature decreases. When the temperature sensor to monitor the CPU temperature is reduced to the following critical value, the fan will stall as long as the system is running, this cycle has been carried out. According to this theory, if the aluminum thermal efficiency high enough to fully distribute the heat given off CPU, so that the temperature sensor detects the temperature is lower than the threshold value, then the fan will not start. Such as greatly reduced the number of fans start, the noise will be greatly reduced, not only can extend fan life, while also reducing the possibility of system failure.

I have a laptop computer, used for some time, as long as the workload of a large, fans immediately started to run a long time to stop, that the noise really annoying, and decided some good hands-transformation .

First step: the first keyboard with a small screwdriver withstood the top of the clamp, gently off the keyboard.

Then you can see some of the heat the machine, press the CPU on a piece of cast aluminum, curved top with a flattening of copper, aluminum stick embedded in the groove, the end In the CPU at the top of the other end extends to the outermost end vents. According to the author of the test and use, found that manufacturers improve the design of the cooling effect of a very small role, because when the heat when accumulated to a certain extent, the heat pipe with the aluminum temperature is the same, can not form a large temperature difference. Fans will not reduce the number of open.

Second step: cooling board in accordance with the text logo, the fixing screws removed in accordance with the order 1-3-2-4. The aim is to prevent the pressure is not balanced and crushed because the edge CPU.

Heat wave plate carefully, pay attention to unplug the board the power supply fan and the motherboard plug. This time you can see below the cooling plate in contact with the CPU where there is a soft, pewter-like sheet, according to tests, I found that the sheet is redundant, not only can not increase the close contact with nature, also may increase the difficulty of cooling So I get rid of this sheet, coated with graphite powder to gel, reducing the gap may be generated.
