Which side is best to apply silicone to a notebook?
Best applied to GPU and CPU.
Don’t do too much at one time, just dot a drop of silica gel directly on the center of the surface of u
Then when installing the heat sink, due to extrusion, the silica gel will be evenly distributed on the surface of u. Squeeze it slightly. It won't matter if it comes out a little and touches the circuit board.
Applying silicone in this way can ensure maximum contact with the heat sink and the existence of floating bubbles in the center.

1. Be sure to clean off all the old silicone and then apply new silicone. There are principles when applying silicone, not thicker The better, it will affect the thermal conductivity. 1 mm is perfectly fine. Do not exceed 2 mm thick. But it must be even.
2. Generally, only the CPU and graphics card (GPU) of notebooks need to be coated with silicone. Some motherboards The chip also needs to be coated with silicone. To put it simply, any main chip connected to the heat sink and heat dissipation copper tube needs to be coated with silicone.
3. According to the picture you uploaded, the entire chip does not need to be coated with silicone. Apply, only apply the metal part. It is the part that is in contact with the heat sink and copper tube.
I hope it can help you. If you have any further questions, please communicate again. There is no problem that cannot be solved, don’t imagine it. It is very difficult or complicated, but this problem can be solved by yourself.
How to apply notebook CPU cooling silicone
Just apply it on the fan and heat sink, because it is large Most notebook CPUs do not have a separate fan. The heat sink is connected to the CPU and the chip, so just apply it on the fan and heat sink. The important thing is not to use ordinary desktop cooling silica gel (white). The effect is not good. Use gray heat-dissipating silicone.
1. When extruding, the nozzle of the thermal paste points to the center of the die on the surface of the CPU. Do not squeeze from left to right like squeezing toothpaste, because when installing the heat sink, the pressure will push the thermal paste on both sides of the die outward, and the excess thermal paste will be pushed close to the capacitor.
2. The Die part of the Athlon series CPU is very small, so you only need to squeeze out the thermal paste that accounts for about 1/4 of the Die area.
3. The Die protective cover of the P4 CPU has a large area. To squeeze out the thermal paste, you only need to squeeze out about 1/9 of the Die area. Some people think that the surface of P4 should also be covered with thermal paste, but in fact this is unnecessary. It is enough for the thermal paste on the P4 surface to be squeezed into a circle with a diameter close to the length of the metal cover. Too much may easily contaminate the CPU socket and motherboard.
4. If the amount of thermal paste is slightly more than the above proportion, you can use paper to gently wipe off the excess thermal paste.
5. If too much thermal paste is squeezed out, it is best to completely clean the contaminated parts other than the Die before trying again. Because if you don’t understand the conductivity of a certain brand of thermal paste, contaminating resistors, capacitors and the thermal paste of Xiaojinqiao is enough to cause a short circuit and burn the CPU.

Method/steps
1
Get a book, first make sure it is all It just needs to be disassembled or partially disassembled. Look at the back cover of the book. When you open the back cover, you can see the cooling fan, which does not need to be completely removed.
2
When the back cover of this notebook is opened and the fan is obviously not visible, it is completely removed. The yellow one in the picture is the radiator, and next to it is the fan.
3
Use a flat-head screwdriver to remove all the screws at the back. Be careful, otherwise you will not be able to open the notebook. Generally, screws are slightly larger. You can remove the back cover first.
Remove the optical drive. There are usually smaller screws under the optical drive to tighten the drive casing.
Then remove the hard drive. Sometimes there are screws under the hard drive, and the hard drive must be removed, as well as the network card. The memory module does not need to be removed.
The next step is to remove the keyboard. There is also a screw under the keyboard. This screw is very important. This is also a basis for whether the laptop is free of charge (trademark affixed by the manufacturer). I hope everyone will consider it carefully. There is a cable on the back of the keyboard. You need to be careful to disassemble it. Generally, you can remove the cable by pressing it upwards.
The only thing left is to separate the notebook and open it bit by bit. Don’t be anxious. I can only say that if you encounter a place that is difficult to open, first check whether there are any screws that have not been removed. This must be paid attention to. arrive. When completely separated, the touchpad and power switch are also connected to the motherboard by cables, which should also be noted.
After seeing the motherboard, you must remove it. Generally, there are one or two screws on the motherboard.
Remove all the cables, including the main screen cable, power cable, speaker cable, etc. connected to the motherboard. This removes the motherboard.
Next, remove the radiator and fan (remove the fan first). The main purpose is to check whether the silicone of the CPU has dried. When it dries, you need to reapply silicone. The premise is that all the previous silicone must be removed (must be removed). This is a casual step. Silicone can be purchased at computer repair stores.
Everyone should note that what we are cleaning is the radiator, that is, the brass metal thing, as well as the fan, hair dryer, and brush. Do not wash it with water.
After cleaning, it can be assembled. Be sure to take your time and don't be too hasty and forget to connect the screws and wires.
Steps to read
After completion, shake the notebook to see if there is any sound to prevent anything from falling into the notebook and causing a short circuit.
How to apply silica gel to laptop CPU
Just apply it thinly and evenly. You can use a hard thin piece of paper or something to scrape it a few times to make it more even. Place the radiator against the CPU first and slowly work on it. Put it down and squeeze out the air. The silicone grease fills the gap between the CPU surface and the non-contact part of the radiator. If it is thickened, it becomes the CPU. The silicone grease conducts heat to the radiator, which is equivalent to an extra layer and makes it difficult to view the original post gt; gt;
How to apply notebook cooling silicone
First of all, please note that it is silicone grease (silver white or silver gray paste) rather than silica gel. Silica gel has poor thermal conductivity and will The two sides stick together and are difficult to separate. Silicone grease is applied between the graphics card chip and the base of the heat sink. The principle of action is to fill small gaps and accelerate heat conduction. It should be noted that the silicone grease only needs a thin layer, as thin as possible, otherwise it will be counterproductive (too thick will cause poor thermal conductivity). Purchase a 1.5g package of ES thermal grease, which is enough to add to three notebooks. In addition, users can use their own thermal grease to replace the original silicone grease of the notebook. Every time you clean or replace the silicone grease, you must do it after the power is turned off. After removing the back cover, you can see the main components of the entire product. The fan is located in the lower left corner. The dual copper heat pipes start from the fan and cover the processor, Northbridge chip, and graphics chip. In addition, you can also see two pieces of memory. and memory slots. Removing the Fan The first step is to remove the fan. The disassembly method is very simple. Remove the two fixing screws, pull out the 3-pin connector, and the fan can be removed. Knowing the location of the processor part of the heat pipe path and the heat pipe graphics chip part, it is very convenient to disassemble. Remove the four screws on the processor, and then remove the two screws on the graphics core, and we can easily remove the heat sink. Take it out together with the heat pipe and put it aside for cleaning. The fixing screws on the heat pipe are protected by plastic washers to prevent loss, so we can safely dry the heat pipe without worrying about losing the screws. Clean the heat pipe and heat sink. Clean the previous thermal grease on the heat pipe. The cleaning process will be more cumbersome. Remove the remaining old silicone grease. After cleaning the heat pipe, carefully handle the old silicone grease attached to the chip so that it can be replaced with new silicone grease.
Note that you must be careful when cleaning silicone grease and do not use sharp objects to clean it to avoid scratching or bumping the fragile components of the CPU and other chips. Wipe clean Intel Core 2 Duo P7450 processor. In addition to the CPU, there is also a north bridge chip, a display chip, and two solid capacitors. It is necessary to wipe the old silicone grease clean and then apply new silicone grease. The method is the same as that of CPU. Add new silicone grease After cleaning, you can add new silicone grease. Remember not to use too much. Just dot some in the center of the chip. When placing the heat pipe, the squeezing force will naturally spread it. Finally, assemble all the cleaned parts back to their original positions, install all the removed parts back in their original positions, and replace the back cover. Turn on the power, turn on the machine and conduct a temperature test. If the temperature does not fluctuate greatly and the temperature value is stable, it means there is no problem with the silicone grease replacement. When applying silicone grease, you need to pay attention not to apply too much silicone grease, let alone to come out from the edge of the chip or heat sink. Chips such as the CPU are very fragile and do not have protective covers, so be extra careful when cleaning and wiping them. Note: It is risky for individual users to replace silicone grease by themselves. Please do not replace it blindly. If you are not confident and have the professional skills, please send it to a professional after-sales repair center. If any problems arise, you are responsible for the consequences.
How to apply silicone on a laptop?
Unless you have separated the heat pipe radiator from the CPU, it is best not to replace the laptop's CPU silicone casually. The specific method is to evenly apply silicone grease to the CPU surface before installing the CPU cooler. The amount should not be too much. You only need to cover the CPU surface with a thin layer, because the silicone grease will be heated when the CPU dissipates heat. It is in a semi-melted state. If too much flows out, it may flow near the motherboard and CPU socket, which can easily cause problems such as motherboard resistance or CPU pin short circuit. If you don't know how to handle it yourself, it is best to ask a professional to do it. In addition, the solid silica gel of notebook computers is paper-like and is not easily available on the market. If you use ordinary desktop silica gel instead, the effect will not be good, so it is recommended not to replace it randomly.

Is that heat dissipation silicone grease?
Just fill it all over. No bubbles, spread evenly.
How to apply silicone to laptop graphics cards
Just apply a thin layer evenly on the chip, do not apply it too thickly.
Illustration of how to apply CPU silicone
Don’t apply too much, one square centimeter is enough, then apply it evenly with your fingers and press it on the radiator.
If it is a boxed CPU, there is a layer of silicone grease under the radiator, so you don’t need to apply it, just install it directly. However, this kind of silicone grease is very viscous. When you take the radiator, don't pull it out straight up or down, otherwise you may pull out the CPU and bend the pins, which will be a painful lesson.
