Recommendations, 1Remove all the silicone grease.

2.Then go to the computer city to buy heat dissipation grease.

3.Apply evenly to the CPU.

You can not have the old machine, but the new machine is very calorific, such as Celeron D, and those must be used.

It's okay, I don't often wear silicone.

As long as it's not completely removed, it doesn't make much of a difference (without overclocking).

If you are not at ease (it is indeed not as good as the previous one), you can ask for a tube from the computer city (no money), and then wipe off the previous one and paint the new one on it.

Note when drawing: Don't apply evenly, apply a little, just press it with a fan.

It's fine, though, you can buy a bottle and apply a thin layer from scratch

It should be said that silicone grease is better than silicone, and it can't be taken off after the silicone is glued. The situation you mentioned doesn't have much impact, but it still has a little impact, mainly the heat transfer problem.

It has to be used. Water-cooled radiators also need the right amount of silicone grease to ensure good cooling results.

The function of thermal grease is to fill the gap between the CPU and the heat sink and conduct heat. Because there will inevitably be a gap between a good heatsink and a CPU.

Therefore, whether you use an air-cooled or water-cooled CPU heatsink, you need to use thermal grease to fill the gap between the CPU and the heatsink, so that the CPU can achieve better heat dissipation function.

1, Master Lu is**.

2. You can know it by touching your hands.

3. This problem can't be solved by changing silicone, and general notebooks will be like this. No hot air, is your CPU fan broken? We call it thermally conductive silicone here and it looks like the same thing as Cooler Supreme, buy gray, the color is different, the material is different.

Finally, your question, ** a professional fan blowing air inside...

Silicone grease should be used inside the CPU, and thermally conductive silicone should be used between the CPU and the heat sink. Remove the CPU and take a razor blade, ask for a new, no notch, then carefully scrape along the CPU shell, and gradually go deeper, be careful when scraping, don't touch the electronic components under the CPU nameplate, once it touches your CPU, it will be scrapped, remove the silicone grease on the original CPU core after removing the nameplate, and then reapply a thin layer, then apply a thicker layer at the same position on the nameplate, and then smear a circle along the periphery of the nameplate, move quickly to avoid silicone grease coagulation, When done, carefully close the lid and press to make sure the CPU and nameplate fit snugly. Then put the CPU into the CPU cover, and apply heat dissipation silicone on the surface of the CPU nameplate and the joint with the radiator, and turn on the device when it is finished.

Apply silicone and silicone grease to the front waist to clean up the dust.

Let's popularize science first: the scientific name of thermal paste and heat dissipation paste is thermal grease (electronic city shouts thermal conductive silicone or silica gel); The adhesive and curable ones that can conduct heat are called thermal conductive adhesives, but the thermal conductivity is not as good as that of thermal grease (such as ST922 thermal conductive adhesive); There is also a thermal conductive silica gel sheet, which can be cut into different shapes, sizes and thicknesses like plasticine, and is more convenient to use than thermal grease, but the thermal conductivity is not as good as that of thermal grease, and it is generally used in electronic products with little calorific value;

Landlord, your notebook CPU generates a lot of heat, I don't know what kind of silicone grease you use, the general notebook recommends using high-end internal type such as: TG This kind, silicone grease is only a thin layer on top of the CPU, and more will affect heat conductivity. And you don't confuse the notebook graphics card chip, CPU chip, and video memory chip, there is a gap between the notebook graphics card chip and the heat sink (the gap is different for different brands and models) Manufacturers are pasted with thermal conductive silicone sheets, here I suggest tearing off the silicone sheet at the gap position of the graphics card and replacing it with a copper sheet coated with thermal grease on both sides, and the memory position can be replaced with silicone grease or thermal conductive silicone sheet.

What is the brand of your notebook, you say that the air outlet is not hot, is there a problem with the exhaust system, in addition, the notebook should not only be dissipated at the bottom, the pen is generally dissipated around, silicone grease has a certain heat dissipation effect, but it is auxiliary, and the heat dissipation itself has a lot to do with the material.

Don't use glue That glue will stick to the grease The temperature is high Is the air outlet windy Is the fan whirring Sometimes it's not that the fan is dirty, it's that the air outlet is blocked with a layer of soil.

Silicone grease is better, it is not recommended to use 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.

There is no alternative product, when the CPU does not have silicone, you can buy silicone to supplement it. CPU application silicone grease steps: 1. The general chassis of the rough source disassembly has only two fixing screws, which can be removed with a screwdriver.

When disassembled in this way, it will not hit other devices due to falling. Second, remove the power supply cable between the fan and the motherboard first, and pull it out directly. Then unscrew the four screws on the edge of the fan to remove the fan and clean the fan and heat sink.

Four set screws, first loosen diagonally, then unscrewed. The heat sink and fan are cleaned with a brush and vacuum cleaner. 3. Clean, first use a vacuum cleaner to absorb the attached dust and fluff inside, and for stubborn dust, loosen it with a brush first, and then vacuum it.

After that, wipe the silver with a damp paper towel and let it dry. Wipe it with a damp paper towel and dry thoroughly before it can be powered on. 4. Erase the old silicone grease with a scraper or cloth to wipe off the old silicone grease covered by the surface of the CPU, the attachment of the silicone grease is not very strong, and the family can scrape it off, and generally clean it up until you can see the font size of the CPU table flushing surface.

Then clean up the dust around the back of the CPU, but the dust in the CPU card slot, just use a brush and vacuum cleaner. Don't touch the front of the CPU, it's fragile here, and you don't need to clean it.

The specific methods used in CPU thermally conductive silica gel are as follows:

There is no very standard statement on how to coat CPU thermally conductive silica gel, but there are guidelines for cong dust, and the key to coating is to be uniform, no bubbles, no impurities, and as thin as possible.

In fact, many friends like to win by quantity when applying thermally conductive silicone, in fact, this is pushing the CPU into the fire pit. Theoretically speaking, under the premise of ensuring that it can fill the gaps on the surface of the CPU GPU and the heat sink, the thinner the thermal conductive silica gel layer, the better, after all, in terms of thermal conductivity, no matter how good the thermal conductive silica gel is, it is not as good as copper and aluminum.

The method of applying thermal conductive silicone is similar to that of applying thermal grease, but because the thermal conductive silica gel will be melted by the CPU at high temperature when it is used for the first time, it will be evenly bonded to the CPU and the heat sink after Cong Xiang, and when the temperature drops and cools, the silicon gel will closely connect the CPU and the heat sink together, so it is necessary to pay attention not to apply too much when applying, otherwise the silica gel after high temperature melting will flow to the CPU socket, which will not only stick the CPU firmly to the CPU socket, And there is also a possibility of insulating the pins of the CPU, causing the CPU to not work properly.

The correct application method can make the heat dissipation of the CPU achieve the best effect.
