How to stick thermal conductive silicone grease on the calculati

1. There are many reasons for the low computing power of S7 bitcoin
1. It may be the problem of temperature. Low or high temperature will affect the calculation power of the miner
2. There are problems in the miner itself, which lead to abnormal calculation force
3. The aging of mining machine leads to the decrease of calculation power, and the calculation power of second-hand mining machine is relatively the first
bitcoin, Leyte coin, sand coin and all the mining machines that need mining are like this.

Refer to the correct method of applying thermal conctive silicone grease:

1. point a small amount of thermal conctive silicone grease in the center of CPU shell. The container of silicone grease is not necessarily a needle tube, but also a vial. You can pick a small amount of silicone grease with toothpick and place it in the same position

   

2. if the viscosity of silicone grease is low, the radiator can be directly installed, and the silicone grease can be pressed open by the radiator base to spread into a thin layer. If the viscosity of silicone grease is high, use a small cardboard or plastic sheet to scrape the silicone grease, so that the silicone grease is evenly spread on the CPU shell and spread out into a thin layer (pay attention not to get it on the hand as much as possible. If the thermal conctive silicone grease sticks to the hand, it needs to be washed n times before it can be washed off)

3. silicone grease is not easy to be coated too thick, because its thermal conctivity is not as high as that of metal, let alone overflow the edge of CPU shell and stick to the motherboard

4. the heat conction effect of two metals in close direct contact is the best. But the reality is always "cruel", the naked eye looks at the smooth metal shell of CPU, the real surface state under the microscope, the role of silicone grease is to fill these tiny holes. If there is no silicone grease, then the thermal conctivity medium in these pits is air, and the ranking of thermal conctivity is as follows: metal (copper, aluminum) > silicone grease > air. Therefore, a thin layer of silicone grease is the correct coating method

3. If your radiator is glued to the bridge, it may be "double-sided adhesive"
if the radiator has clips, it is OK to apply silicone grease between the radiator and the bridge

4. First of all, you need to understand that the thermal conctivity of thermal conctive silicone grease is definitely not as good as that of metal direct contact, so don't believe in the nonsense of painting more.
in fact, the role of thermal conctive silicone grease is to fill the invisible gap between the fan base and the CPU surface, so if your radiator base is very smooth - such as the mirror surface, you can paint it as thin as possible, If you can't see your own face, for example, you can paint a business card as thick as it is = =

the most convenient and efficient way is to use plastic gloves for eating. If you can't find it, you can also use plastic wrap instead. There are really no two. In the bedroom, you can use business cards and other things to finish it slowly...

in addition, squeeze a little in the middle, Then the method of pressure dispersion when the radiator and CPU contact is OK, the effect will not be too bad, as long as you don't have high temperature requirements

5. If the thermal conctive silicon film is pasted, it is unnecessary to apply thermal conctive silicone grease; It depends on the situation to apply silicone grease directly and stick thermal conctive silica gel, but generally speaking, the thermal conctive effect of directly applying thermal conctive silicone grease is better; Thermal conctive silica gel is suitable for filling chips with large gap and low calorific value. If the chips with high calorific value have to consider the design problem or use imported phase change materials to fill.

6. This kind of question is not correct, they have their own advantages, and there is no better question than who
the choice depends on your craft
the thermal conctivity of the thermal conctive gasket is not very high, and the actual thermal conctivity is the worst, because it can not completely fill the gap of the contact surface, but it has physical toughness, does not need to be solidified, and the process operation is simple, so it is suitable for applications with low thermal conctivity requirements
the thermal conctivity of thermal conctive silicone grease is very high, but there is no curing mechanism; Suitable for applications with high thermal conctivity requirements
thermal conctivity silica gel is usually not very high, but there are also procts with high thermal conctivity on the market. He is characterized by adhesiveness (adhesive force cannot be his main function). It needs curing
the above is just a brief introction, and there are many more details.

Clean the st of the computer and replace the silicone grease. When removing the heat dissipation mole, it was found that there was resial silicone grease on the chip and the heat dissipation copper tube. Wipe off the silicone grease with a dry soft cloth. The next step is to apply silicone grease. The coating method is very simple. Because the notebook processor has no top metal cover, you can see the chip directly, and the area is small, so you only need to extrude a piece of silicone grease in the center of the chip, and remember not to too much, so as to ensure that the silicone grease is evenly distributed on the chip after extrusion

then install the cooling copper tube and fan in a reasonable order, and slowly tighten the screws around the chip. Be sure to screw slowly. Use this operation for disassembly. Tighten each screw first, then graally tighten all screws

extended data

operation method of st removal before silicone grease application:

I. disassembly machine

different notebook computers have different difficulty in disassembly. In general, it is recommended to check the corresponding disassembly tutorial first to judge the difficulty of disassembly, and then decide whether to disassemble

after confirming that the machine can be operated, disassemble the machine according to the instructions, and store the screws according to the category ring the disassembly process. It's better to add labels, otherwise it will be embarrassing to install more screws. In the process of disassembly, when the buckle is fastened, the crowbar can be used to pry it out slowly. Do not use too much force, it is easy to damage the motherboard components

there is no need for st removal, as long as the heat dissipation mole can be removed. After opening the bottom shell (the inverted model is the C side), first disconnect the battery from the motherboard and remember this

it is more careful to remove the heat dissipation mole than the shell. First of all, disconnect the fan cable, gently pull it out, shake it left and right, and the shaking range is as small as possible

Next, screw off the copper tube on the chip. Do not screw out the screws in turn. In order to avoid extrusion of the copper tube at the edge of the chip, it is better to loosen about half of each screw first, and then screw it out. Finally, remove the copper tube. If it is too tight, shake it to the left and right to remove it. Don't pull it out

After removing the cooling copper pipe, the st removal is mainly concentrated in the fan and radiator. Shark fin is easy to clean, just brush and blow. The fan is a bit of a problem. You need to remove the fan first, and then clean the fan blades. After unscrewing the screws of the fan and removing the baffle, first clean the fan blade and its surroundings with a brush. There may be a lot of st in this part. Masks are recommended

Do not use water when cleaning. In addition, after cleaning the radiator and fan, check other internal locations for st, and clean with a brush and blower

8. In fact, the two are only different in form (solid, liquid), and the function and principle are the same, so which one is good depends on the quality of the proct. Because of the special shape of thermal conctive adhesive, its flexibility is not as good as silicone grease. The quality of procts available on the market can only be said to be in good order. Because of its convenient use, the development of silicone grease is better than thermal conctive adhesive. Many high-grade silicone grease containing metal has excellent thermal conctivity. Therefore, on the premise that the price is acceptable and you don't have the trouble of fixing the heat sink, I personally think it's more appropriate to choose medium and high-grade silicone grease containing silver or even gold than thermal conctive adhesive

in addition, the problem you mentioned does exist, because the application of silicone grease is a technical activity, too little can not achieve the effect, too much and too thick can backfire, and uneven application will also affect the effect, especially when using low-grade silicone grease.

9. No matter how smooth the surface is, there are concave and convex surfaces. If there are concave and convex surfaces, they will not be closely combined. If they are not closely combined, there will be voids. Even if nano silicone grease is used, the voids can not be 100% tightly combined. The thermal conctivity only depends on the thermal conctivity. The heat dissipation of the radiator depends entirely on the thermal conctivity of the radiator fin material, So your radiator as long as to ensure that the heat transfer to meet the maximum heat sink can, there is no need to add heat sink.
