What is the white powder on the CPU, and what is the white thing applied to the CPU? What s the use?

Is it something that can be rubbed on your hands? If it is, it can only be CPU heat dissipation grease, which will dry and turn into powder after a long time. Good silicone grease also dries, but it dries for a longer time, and the inferior one hardens in less than 2 months, and the good one can be used for about 2 years.

That's the traces left by thermal grease.

Now the hardware will inevitably rise a little bit in price, because of the New Year's holiday problem, manufacturers have to take a holiday, so in the coming days there will be a false shortage of stock, scarce is expensive, the supply is small, it will inevitably rise in price, and memory particle manufacturers in December 16 suddenly increased the ex-factory price of particles, so December 18 afternoon memory formation price increase, and it has not come down until now, it is estimated that after the Chinese New Year, the hardware will have a medium-intensity price reduction after the installation heat.

Now the latest CPU should be Intel's i7,Whether this CPU will not reduce the price for a long time depends on when AMD will come up with a CPU that can compete with i7,AMD's latest Yilong 2 is defeated by i7,And the positioning is about 1,000 yuan,So i7It is difficult to drop below 2,000 yuan in the near future。

Now change the computer, the most suitable is the 45nm CPU, now 45nm has been popularized (45nm PE5200 is now the best cost performance) This is Intel's strategy, Intel will upgrade the architecture or process every two years, 95nm Pentium, to 65nm Pentium, after the new core, then 45nm Core, and then the current i7, it is estimated that at the end of 2009, the 35nm process i7 will come out, At that time, the i7 should start to become popular (but it depends on what AMD has for the i7, if you really can't take it, the i7 will always be high).

Now if the mainstream machines are about 3000 yuan, with Intel 5200 as the mainstream, AMD with K10 architecture 7750 as the mainstream, so these two processors are now the most suitable, in terms of platform, Intel takes the P43 platform as the mainstream, and AMD takes the three platforms as the mainstream.

In October next year, this new i7 CPU will be popular, because there is no way that AMD will not be able to come up with a powerful CPU for so long! If the i7 can't be popularized, at least the Q series CPUs with 4 cores can be popularized.

Heat Sink Dry and apply new grease from the ground up.

Thermal grease. <>

1. Thermal grease.

Commonly known as heat dissipation paste, thermal conductive silicone grease is made of silicone as the main raw material, adding materials with excellent heat resistance and thermal conductivity, and is used for thermal conductivity and heat dissipation of electronic components such as power amplifiers, transistors, electron tubes, CPUs, etc., so as to ensure the stability of the electrical performance of electronic instruments and meters.

2. Thermal grease.

It is a high thermal conductivity insulating silicone material that almost never cures and can be maintained in the grease state of use for a long time at temperatures from -50 to +230. It not only has excellent electrical insulation, but also excellent thermal conductivity, and at the same time has low oil separation (tends to zero), high and low temperature resistance, water resistance, ozone resistance, and weather aging resistance. It can be widely coated in various electronic products, electrical equipment between the heating element (power tube, thyristor, electric pile, etc.) and heat dissipation facilities (heat sink, heat sink, housing, etc.), playing the role of heat transfer medium and moisture-proof, dust-proof, corrosion-proof, shockproof and other properties.

master?

I just looked at the name, but I couldn't understand it.

What I know is like trying to smear him flat

After the hot search, there is an answer.

Here's the thing: no matter how well-made the heatsink is, there will inevitably be gaps when it comes into contact with the CPU, so it is necessary to use thermal grease to fill the gap between the CPU and the heatsink. By increasing the contact area between the two, the effect of heat transfer is improved.

However, it should be noted that because the thermal conductivity of metal heat sinks is much stronger than that of thermal grease, the use of thermal grease here is only used to fill the gaps, not to connect the CPU and heat sinks. There are three main types of DIY thermal grease on the market: white thermal grease, gray thermal grease and a rare black thermal grease.

White Thermal Grease: This type of thermal grease is the most common. At room temperature, it is a viscous liquid state, which is divided into several grades due to the addition of different amounts of metal silver powder in silicone grease, the difference is that their viscosity is different, and the composition of metal silver powder is the better the heat dissipation effect, of course, the higher its **.

Gray thermal grease: This kind of thermal grease is the original thermal grease of Intel company, it adds a certain amount of graphite powder to the thermal grease to enhance the thermal conductivity effect, if you feel that there is not enough graphite powder in this silicone grease, you can also add some by yourself. Place the gray thermal grease on the glass plate, then grind the pencil on it, and stir with the grease as you grind.

However, it should be noted that you should not use too much force during the grinding process, otherwise the pencil lead particles will be too large, which will affect the thermal conductivity. Black Thermal Grease: There is no secret to this "colored" thermal grease, except that a small amount of solder powder is added to the thermal grease, and it is said that its heat dissipation effect is the best among thermal grease.

It's not called silicone, it's called silicone grease, which helps the CPU and the heat sink stick tightly, can't dissipate heat, and can conduct heat to the heat sink, and finally achieve heat dissipation.

It's called silicone, and it's used to make the CPU and fan bond better, without which it will cause poor heat dissipation due to insufficient contact between the CPU and the fan. It's cheap and it's available everywhere in the computer city.

This one helps the CPU dissipate heat, and it's called silicone.

It is a "thermal grease", which is used to fill the gap between the CPU metal shell and the metal base of the radiator, enhance the thermal conductivity, and make the heat generated by the CPU better conducted to the radiator, and then dissipated from the radiator fins into the air.

That's thermal paste, which is used to dissipate heat, and too high a temperature can cause an automatic reboot and a blue screen

No, the white substance is silicon, and the blue screen has nothing to do with it, it plays a role in heat dissipation, and it has nothing to do with it.

What is left after the silicone grease has dried.

Answer: The landlord is quite humorous. Toothpaste can also be used for this.

I'll tell you to put it. The white stuff is called silicone. This stuff can't be too much. Nor too little.

Blue screen for many reasons. I'll write it down.

1。The system is unstable.

2。Virus. 3。Software.

4。Memory. 5。Cooling.

6。Graphics. CPU overheating generally causes frequent machine crashes. Serious ones will burn out. Motherboards and other components.
