Advantages of thermally conductive silicone sheet:
1. The material is soft, the compression performance is good, the thermal conductivity and insulation performance are good, the adjustable range of thickness is relatively large, suitable for filling cavities, the two sides have natural viscosity, and the operability and maintenance are strong;
2. The main purpose of selecting thermally conductive silica gel sheet is to reduce the contact thermal resistance between the surface of the heat source and the contact surface of the heat dissipation device, and the thermally conductive silica gel sheet can well fill the gap of the contact surface;
3. Because air is a poor conductor of heat, it will seriously hinder the transfer of heat between the contact surfaces, and the installation of a thermally conductive silica gel sheet between the heating source and the radiator can squeeze the air out of the contact surface;
4. With the supplement of thermal conductive silicone sheet, the contact surface between the heating source and the radiator can be better and fully contacted, and the face-to-face contact can be truly achieved. The reaction in temperature can achieve the smallest possible temperature difference;
5. The thermal conductivity of the thermally conductive silica gel sheet is adjustable, and the thermal conductivity stability is also better;
7. The process difference of the thermal conductive silica gel sheet in the structure is bridged, and the process difference requirements of the radiator and heat dissipation structural parts are reduced;
8. Thermally conductive silica gel sheet has insulating properties (this feature requires adding appropriate materials in the production);
9. Thermally conductive silicone sheet has the effect of shock absorption and sound absorption;
10. The thermally conductive silicone sheet has the convenience of installation, testing and reuse.
Disadvantages of thermally conductive silicone sheet:
Compared with thermal grease, thermal grease has the following disadvantages:
1. Although the thermal conductivity is higher than that of thermal grease, the thermal resistance is also higher than that of thermal conductive silica gel.
2. The process of thermal conductive silica gel sheet below the thickness is complex, and the thermal resistance is relatively high;
3. The temperature resistance range of thermal grease is larger, they are thermal grease -60 300, thermal conductive silica sheet -50 220;
4. Thermal grease has been widely used, low, thermal conductive silica gel sheet is mostly used in laptops and other thin and precise electronic products, slightly higher.

The heat dissipation silica gel sheet is generally placed between the heat source device and the cooling fan to play a role in heat conduction. You can fix it mechanically, with screws for fans and heaters, and a silicone sheet in between. If the force is not large, it can also be bonded with thermally conductive silicone.

Heat dissipation silicone, also known as thermal conductive silicone or thermal paste, is mainly used to fill the gap between the CPU and the heat sink to improve the heat conduction efficiency. When there is no special thermally conductive silicone, you can try to use the following materials instead:
1.Clear silicone grease: Clear silicone grease is a common substitute and usually consists of silicone oil and other additives. Although the thermal conductivity of transparent silicone grease is not as good as that of specialized thermally conductive silica, it can still provide some thermal conductivity.
2.Solid-state thermal conductive silicone grease: Solid thermal grease is a special thermal conductive material in the world, mainly composed of metal powder, silicone oil and additives. It conducts heat better than transparent silicone grease, but slightly less than specialized thermally conductive silicone.
3.Toothpaste: Toothpaste contains some ingredients that can improve thermal conductivity, such as silicates and aluminum. While toothpaste may not be a complete replacement for specialized thermally conductive silicone, it can be used as a temporary replacement in the absence of other options.
4.Heatsink: Add a heatsink directly between the CPU and the heatsink to increase the heat conduction area. However, this method may not provide the same results as a dedicated thermally conductive silicone and may affect the performance of the heat sink.
Please note that these alternatives may not be as thermally conductive as specialized thermally conductive silicones, so the heat sink may need to be checked and replaced more frequently when using these alternatives. Additionally, when using these alternatives, make sure to follow the manufacturer's recommendations to prevent damage to the electronic device. If possible, it is best to buy special thermally conductive silicone.

Computer heat dissipation silicone can be replaced with some common materials:
Hot glue: This is the most common alternative. Apply the hot melt adhesive between the CPU heat sink and the computer motherboard, and wait for the rubber to solidify and insulate the computer.
Epoxy resin: A resin that dries after mixing two components. It can be applied under the heat sink to secure the heat sink and insulate the heat.
Modeling putty: A plastic clay made of ceramic, which can be strong after molding. Can be applied under the heatsink instead of silicone.
Ink: Some inks can act as thermal insulation and can be applied to the CPU as an alternative to silicone.
Glue: Some strong glues can also replace silicone. It is better to choose a special computer glue.
These common alternatives can be purchased at home or in supermarkets and can be used in moderation depending on the situation. Be sure to make sure that you do not damage the computer components before use.
Of course, heat dissipation silicone is still the first choice, if conditions permit, it is still more reliable and worry-free to buy a professional hail of computer heat dissipation silicone.

There is no very standard statement on how to apply thermal grease, but there is a guideline, the key to application is to be uniform, no bubbles, no impurities, and as thin as possible.
There are two main ways to apply it now:
1. Squeeze a little silicone grease in the center of the surface such as CPU and GPU, and then squeeze the silicone grease evenly by the pressure of the radiator;
2. The method is to evenly apply silicone grease to the surface of the CPU, GPU, etc.
Obviously, the first method is suitable for heat sources with a small surface area, and the second method is more suitable for CPUs and GPUs with a large surface area, such as (Intel Core 2 series processors), but the second method is easy to get impurities when applying, and may also produce bubbles.

Summary. No, silicon glue cannot replace heat dissipation glue, because the viscosity of silicon glue is lower than heat dissipation glue and cannot provide sufficient heat conduction, while heat dissipation glue can provide good heat conduction, resulting in better heat dissipation.
No, silicon gelatin cannot replace heat dissipation glue, because the viscosity of silicon gelatin is lower than that of heat dissipation glue, which cannot provide sufficient heat conduction effect.
Excuse me, but please go into more detail?
A: No, you cannot. Silicone grease is a type of silicone grease that has a lower viscosity than heat dissipation glue and does not provide enough support to hold the heat sink to the heat sink.
The reason is that the viscosity of the silicon core manuscript glue is lower than that of the heat dissipation glue, which cannot provide enough support to fix the heat sink on the heat sink. Workaround:
Heat sink adhesive should be used to secure the heat sink to ensure that the heat sink can be securely attached to the heat sink. Personal tip: When installing a radiator, use the right materials to ensure that the radiator works properly.
Related knowledge: heat dissipation adhesive is a kind of thermally stable hot melt adhesive, which has good adhesion and heat resistance, and can effectively fix the heat sink on the heat sink to ensure the normal operation of the heat sink. State stove.

How to use computer CPU heat dissipation silicone.
1. Make sure the CPU surface is clean; 2. Determine the area where the heat sink is in contact with the CPU, and squeeze out the heat dissipation paste, and the amount used is about between; 3. Use a blade to pick up a small piece of thermal paste and transfer it to a corner of the CPU core; 4. Put your fingers into the plastic tape so that the heat dissipation paste at the bottom of the radiator is all over the entire part of the CPU; 5. Wipe off the heat dissipation paste, and the color is different; 6. Continue to evenly coat the entire core from the corner of the CPU core to see if the heat dissipation paste is thin and transparent; 7. Confirm whether there is any foreign matter on the surface of the CPU and complete it.
Computer CPU heat dissipation silica gel, commonly known as "heat dissipation paste", is a kind of thermal grease, in our daily life, it is a kind of silicone coated on the computer CPU, in order to dissipate heat, widely used in transistors, tubes, CPUs and other electronic components, so as to ensure the stability of the performance of electronic instruments. It is resistant to high and low temperatures, water and weather aging, and has excellent electrical insulation and excellent thermal conductivity. It is a good insulating material.

Computer heat dissipation relies on fans and heat sinks, and the role of silicone is to absorb moisture.
In order to solve the heat dissipation efficiency of some heating chips and heat sinks of computers and improve the thermal conductivity, "silicone grease" or special silicon-containing film materials can be used as the thermal conductivity layer between the chip and the heat sink.
Prevent uneven metal surfaces from affecting heat conduction"Silicone grease"It can solve the poor thermal conductivity caused by uneven surface.
There are also places that not only need to conduct heat efficiently, but also insulate, and can not use metal, so it is necessary to use insulating thermal conductive materials, silicon-containing diaphragms, and plastic films.
Silicone and "silicone grease" are two different things.
