Notebook cooling up to more than 10 degrees

Notebook cooling is already a commonplace topic, see again into the summer, the weather day by day heat up. For the urban white-collar people who often want to use laptops, or those who like to play games or use laptops to learn, notebook temperature is too high and will become a headache in the summer.

Due to the small space inside the notebook, the high performance and high load operation of each component will bring too much heat to the notebook. In the winter, these calories can be properly exported through a laptop's thermal design, which does not have a significant impact on notebooks. However, in the summer, as the ambient temperature rises, the laptop's cooling design will not be enough to meet the requirements of the notebook temperature, so summer notebook cooling will become the key to determine whether it can run smoothly.

In fact, in the summer to effectively reduce the temperature of the notebook, so that it can work normally, no need to start from four aspects. Stable, low temperature use environment, thermal accessories, hardware cooling transformation and software cooling. The following author from these four aspects, respectively, for everyone to introduce how to cool the notebook.

Judging the notebook temperature

Before introducing the method of cooling the notebook, we must first learn how to judge the temperature of the notebook and how high the temperature is normal, here to provide you with two ways. The first is relatively simple, is not very accurate, is to touch the keyboard and the bottom of the notebook directly, generally speaking, the hands feel warm, notebook temperature should be around 45 ℃, feel hot, but also can be continuous contact, the temperature should be 55 ℃ or so, feel hot, but can endure a few seconds, the temperature should be around 70 ℃ , feel very hot, touch a bit and don't want to touch the second, the temperature should be around 80 ℃. Note that this is only the external temperature of the notebook, and when the temperature is 55 ℃, then the CPU temperature should be 65 ℃ or so.

And the second method is more accurate, more professional, is to use software to test the temperature of the notebook, generally we are more familiar with such as Lu Master. With this kind of software can be more accurate to measure the notebook CPU, graphics card and other hardware temperature, so that users can have a certain understanding of the cooling of the notebook.

Test notebook temperature with Lu Master

So, how high is the temperature of the notebook normal? The temperature of the general CPU should be guaranteed in the range of temperature rise 30 ℃, that is, if your ambient temperature is now 20 ℃, then the CPU is best not more than 50 ℃, according to the summer up to 35 ℃ to calculate, the CPU temperature is 65 ℃, temperature is of course the lower the better and apparent card CPU to serious, the thermal temperature is 120 ℃ notebook graphics, warning temperature is 90 ℃, usually think to 80 ℃ around is normal, full load should be 85 ℃ around, if it is not too normal.

Effective cooling before two strokes low temperature environment and heat dissipation accessories

To make the notebook temperature is low, first of all we must ensure a low-temperature use of the environment. The big summer, more than 30 degrees high temperature, you hold the notebook in the sun to play, then the good heat dissipation design also useless. So, first of all to choose a relatively low temperature, more comfortable use of the environment, for example, the temperature in the room about 28 ℃, or air-conditioned indoor and so on. A low temperature environment is a prerequisite for keeping your notebook warm.

Of course, in the hot summer, even under the fan, the temperature is not too low, so this time we need some auxiliary cooling accessories. such as heat sinks, heat sinks, and so on, these in the general electronic market or online have sales, very easy to buy, and the price is not high. However, some manufacturers in order to let the thermal pad to sell, the very best way, mute and strong fan is presentation, as to how fast the fan, the effect of how good, regardless of, so that most of the radiator cooling effect is not ideal.

The most hated Lu Master's alarm sound, affecting our playing the game when the precious mood. Face a bunch of chicken products, also do not have to pick, their own transformation is the most energy-saving and financial resources. Choose the best modified chicken heatsink, switch the fan to a violent chassis fan.

Recall the size of the chassis fan, it is 12V voltage, USB power is 5V voltage, so the USB power will definitely give up. Buy a small 12V power supply, and then the thread welding, this thing is over ~ How, simple violence it?

There is a representative of the chicken on the hand, the Kyushu winds a thermal pad, visual can know, the inside with the fan, and the standard 12cm chassis fan specifications exactly the same, just suitable for the transformation.

Kyushu Winds-Moon

The built-in fan is the same size as the standard 12cm chassis fan

Go to Computer city small turn around, found selling violent fan of the boss business is very good. Because worry about 220V of super violent fan to blow the notebook to fly up, so still spend 35 yuan to start a 12V of violent fan, by the way with 15 yuan started a 12V small power.

Coupling chassis fan and 12V small power supply

Simply look at the parameters, the fan is 12v-0.27a, the power supply is 12v-1a, you can know that the power can fully drive this fan full-speed operation. And then we started to weld them together.

Cut both the fan and the power connector directly

How to weld the thread? Very simple, red welding red, black welding black, OK. In addition, direct the fan white line (temperature control) cut off, because we do not need any "temperature control."

Do not forget to stick with the insulating tape after soldering the thread.

After a simple soldering, two threads are welded, so don't be afraid, because it's too simple.

Plug directly into the power supply and feel the strong wind

The violent fan is plugged in directly below. Before the transformation, measured my Sony SZ26 notebook in the desktop under the quiet temperature of 47 ℃, temperature and pressure test maximum temperature of 78 ℃. Can be seen, the effect is really very chicken ~

temperature conditions before the thermal pad is retrofitted

After 10 minutes, the thermal pad was removed eight pieces, you can find that the structure is very simple, that is, two pieces of the board holding a fan.

Unscrew the thermal pad by screwing all the screws behind it.

Helpless found that the fan suction tuyere is blocked by the horizontal bar jump, there is no doubt that this will affect the play of violent fans, apart, clamp off with pliers!

Remove these "ribs"

After removing the rib-shaped strips behind the ribs (which is really chicken), the suction tuyere area increased a lot. What, looks bad? Unfortunately, there is no relationship between good-looking and thermal performance, so I think this is very good.

The violent fan is plugged in like this.

After re-loading the thermal pad, you are done. The interface of the power supply is just around the back, still sticking it in the back with the ugliest but simplest method.

My Sony SZ26 on this wild ride.

Are you excited? Don't worry. After the test began, I went out to play, and came back to find the test 100 minutes, the temperature is 7 degrees lower than before the transformation.

Under the table stable at 43 degrees Celsius, 100 minutes pressure test maximum temperature 71 ℃

Recall the temperature without a thermal pad:

The lower the temperature, the better.

Can be seen, this chicken notebook thermal pad After the transformation, performance almost increased by 100%, although it is chicken ribs, but as the material of the transformation, or good drop! 100 minutes high-strength pressure test, the maximum CPU temperature is only 71 ℃, how to ask?
