Which is the higher price of thermal grease or aluminum, and where to buy thermal grease

Thermal grease is a type of high thermal conductivity silicone grease that is commonly used in heat dissipation systems to effectively transfer heat from the heat source to the heat sink, which is essential for the stable operation of equipment. Here's how to use thermal grease: Before using thermal grease, you need to clean the surface of the radiator and heat source to ensure that the surface is clean and free of impurities or foreign objects.

Apply an appropriate amount of thermal grease to the surface of the radiator and heat source to ensure that it is evenly applied. Attach the heat sink to the heat source and press gently to evenly distribute the thermal grease. During installation, care should be taken to avoid excessive force to avoid extrusion or bubbles of thermal grease.

After the installation is complete, a system test should be performed to ensure that the cooling system is working properly. The correct use of thermal grease can effectively improve the efficiency of the heat dissipation system and ensure the stable operation of the equipment. In use....

This one is not easy to compare. Because the use method is different, if it is the same volume or the same weight, then aluminum must be cheaper. Thermal grease is a kind of thermal conductive material used between the aluminum substrate and the shell, or between the aluminum substrate and the heat sink, because it is a thick liquid, so it can fill the gap well.

Although the thermal conductivity of aluminum is relatively high, the filling effect is not very ideal because the metal has a smooth surface but is actually rough.

Question 1: Where can I buy CPU thermal grease? There are many places where you can buy it, and most computer stores have it.

Online JD.com**, Gome**, **, Paipai, etc. can also be bought.

It is recommended to buy CPU thermal grease with high silver content, good thermal conductivity effect, and long use time.

CPU Thermal Grease Application Method:

One is to squeeze a little silicone grease in the center of the surface such as the CPU GPU, and then squeeze the silicone grease evenly by the pressure of the heat sink, and the other way is to evenly apply the silicone grease to the surface of the CPU GPU and other surfaces. 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.

Question 2: What stores generally have thermal grease? Hardware supplies are sold at stores, computer repair and computer assembly places.

Question 3: What kind of silicone grease is generally bought in **? Computer consumables are available at the store!

Question 4: Thermal grease ** has to buy the landlord is buying? Or sell?

The landlord is talking about the thermal grease used in the computer CPU, right?

If you buy it, it is available at each computer store.

Question 5: Where can I buy CPU heat dissipation grease? In the computer store in the computer city, there are 5 yuan and 20 yuan, which is probably the price, if you are in Beijing, go to Zhongguan to see the many things there are also cheap.

Question 6: I bought heat dissipation silicone grease online, can I apply it to the notebook**? 20 points You don't know how to use the silicone grease you buy, and it is not recommended to get it yourself if you have no experience.

Hope it helps......

Question 7: Where do you buy CPU heat dissipation grease and how much does it cost Thermal grease is generally included with the heat sink.

When installing the machine, you can also buy a little and keep it for later use......Even, if you are familiar with the owner, you can ask for a ...... at allAfter all, this thing is not valuable.

Question 8: Silicone grease is generally available in **? You can buy it from an ordinary computer training department.

Question 9: Where is the thermal grease coated? Thermal grease is applied to the back of the CPU, which is the side where the head of the scale is in contact with the CPU fan. Silicone grease is a good conductor for heat dissipation, so it should be applied to the place where it comes into contact with the fan to facilitate heat dissipation.

Those brands are better 20 cents of mu wheel to find a regular thermal grease ** business to buy, it is reliable, such as looking for Tmall store on the Internet, Jingdong, the more famous thermal grease brands are Shin-Etsu, Dow Corning, Hasuncast, etc. Used on CPUs, most of them are more reliable with left and right thermal grease.

Thermally conductive silicone grease can be bought on e-commerce platforms or official websites;

You can consult in advance, choose the right type of product according to your own needs, and purchase it;

1. Shin-Etsu (cost-effective recommendation).

Shin-Etsu's products are well-known in the DIY industry, and the first choice of many installers, among which 7921 is more viscous, and you can choose the 9-point smear method; The 7868 is the "lube" version of the 7921, and the performance release needs to be used for a period of time. Shin-Etsu does not have an official store in China, and it can generally be purchased on JD.com, which is more secure.

2. Limin TF3, TF4, TF7, TF8, TFX (recommended by novices).

Limin (thermalright)'s heat dissipation products are quite reliable, whether it is air cooling, cooling fans have a good reputation. Thermal grease from TF3 to TFX is the choice of many users who pursue stability.

Precautions for applying thermal grease:

1. Apply thermal grease, thickness is very important. In the application stage, there are strict requirements for the thickness of the thermal grease, and the thickness of the silicone grease layer shall not exceed 3mm, which is roughly similar to a piece of white paper. The reason for the strict application thickness is that the thermal grease is applied too thickly, which not only does not have a thermal conductive effect, but also prevents heat energy from being dissipated.

Just apply a thin layer to fill the gap of the radiator, after all, the thermal grease is only an auxiliary heat dissipation material, and the thermal conductivity function of the appliance needs a radiator.

2. The thermal grease is paste-like, non-toxic and tasteless, but the damage to the first class cannot be ignored. If accidentally touched, sensitive** people will experience redness, swelling, swelling, itching and other symptoms, and they need to be washed with water. Disposable gloves can be worn when applying, which can not only protect the construction personnel, but also facilitate the application of thermal grease.

3. During the construction process, the thermal grease can only be applied to the middle of the electric heating element and the heat dissipation facilities, and it is ineffective when used in other places. <>

Domestic thermally conductive silicone brands:

Taiwan Pioneer: Produced in China, thermally conductive silicone tape, complete product series, low thermal conductivity.

Shenzhen Dongcheng silica gel, which entered the industry relatively early in China, is also a more professional brand, with relatively complete products and good thermal conductivity. It is also more cost-effective.

Foreign thermally conductive silicone film brands are:

Bergs, Laird: The product series is complete, involving a wide range of industries, the product performance is good, the first is relatively high, and there is no domestic production base.

Japanese Fuji polymer: occupies a large share in the module industry, has a high thermal conductivity, and has no production base in China, which is relatively high.

Coomei: Thermally conductive phase change materials have a competitive advantage.

Dow Corning: Thermal grease.

Large, ** higher.

Domestic brands have R&D and production capacity, which is relatively low, and the product service is faster, and the foreign ones are generally higher, and there is no domestic production base, and some of them are made up of processing plants.

Silicone grease is a paste made of special silicone oil as the base oil, new metal oxide as filler, with a variety of functional additives, and processed by a specific process, which has good thermal conductivity, temperature resistance and insulation properties. Thermal grease is the most easily ignored in the installation process. It is responsible for the connection between the CPU and the heat sink, and the high temperature generated by the CPU operation is transmitted to the heat sink in time through the silicon grease to effectively cool down the processor.

No matter how good the radiator on the market is, if it is not coated with silicone grease, it will basically "turn on and alarm". Silicone grease is equivalent to the bridge between the CPU and the radiator, if this bridge is gone, the CPU and the radiator will never see each other again in this life, even if they meet, they are scarred and dying.

We know that processors like the 10th generation Core i9 and i7 with K do not come with the original heatsink and need to be purchased additionally. The radiators we bought back, silicone grease will be given away for free, there is a pack, there are also syringe shaped, the specifications are usually or below, and the amount is one or two times. These greases are not labeled, introduced, or explained, and often give players a sense of insecurity.

Therefore, when I usually install high-end machines, the radiator does not use original silicone grease.

There are many kinds of silicone grease on the market, and the formulas are also different, some are expensive and some are cheap, and naturally there are good and bad. To this end, we have found three mainstream thermal greases, namely Xingu Ice Flame V5, Cooler Master Nano Diamond and Limin TF8, with the tenth generation Core i7-10700K processor, to see how different thermal greases perform?

Let's take a look at the parameters first:

When we buy silicone grease, the most intuitive reference standard is to look at the "thermal conductivity", the unit of thermal coefficient is w m k, which refers to the heat transferred through 1 square meter area in 1 second under the condition of stable heat transfer, the temperature difference between the two sides of the surface of a 1m thick material is 1 degree (k, °C). The higher the coefficient, the greater its ability to conduct heat.

Generally speaking, the thermal conductivity above 10 belongs to high-end products, and the thermal conductivity of some more than a dozen pieces of silicone grease on the e-commerce is generally only in single digits. Among these three silicone greases, Limin TF8 has the highest coefficient, Xingu Ice Flame V5 is in the middle, and Cooler Master Nano Diamond is the lowest. Plus, they're all in 2 gram packs, and it's no problem to use them 4-5 times.

**On the list, Limin TF8 is the same as Cooler Master Nano Diamond, both of which are yuan; And Xingu Ice Flame V5**The lowest,**39 yuan。

There are many kinds of thermal grease brands on the market, sometimes it is indeed dazzling, in fact, there are few good thermal grease brands, commonly used are Dow Corning, Hasuncast, Shin-Etsu, etc., other brands, but there are many fakes on the market, pay attention to screening.

At present, the more common is the overclocking triple A1 platinum thermal paste containing 25% silver and thermal conductivity, about 15 yuan a small tube, or Cooler Master ** thermal grease, thermal conductivity, which is also about 15 yuan a small tube. I use both silicone greases. If used on the contact surface between the CPU and the heat sink, a small tube can usually be applied about 10 times.

Compared with ordinary silicone grease, it can reduce the temperature of the CPU or graphics card by more than 5.

The domestic thermal grease market is relatively chaotic, most of them are slightly low-grade products, uneven, compared with Wuxi Lily (old factory), Suzhou Xijia (scientific research unit) is more reliable. The high-end thermal conductive silicone gel is currently a watershed that distinguishes the strength of the enterprise, and the 4W MK thermal conductive gel of Dow Corning, Momentive, Shin-Etsu, and Xijia has responded well.

Silicone grease is actually the best Shin-Etsu, but basically**There are too many fakes, I have bought it a few times, and finally I bought a Mengjiu Brigade's OK,**Very expensive,But the performance is really good, I also want to buy it for 16,000, and the temperature of eating chicken is high,

Thermal grease is not the best, Depu's thermal conductive silicone can, don't apply too much, the main thing is that the thermal conductivity effect is good.
