It's hot, how to help the computer dissipate heat?

According to statistics, 8% of computer failures are caused by insufficient heat dissipation. In fact, there are more computers with heat dissipation hazards than everyone thinks. The heat dissipation of the whole system will directly affect the stability and performance of the computer. In the long run, it is likely to cause more serious problems and cause great harm to the system. Even if your computer looks normal, it is only temporary and still dangerous. Many computer failures in the jar are caused by poor heat dissipation, so everyone must pay attention! 1, computer environment Choose the coldest place in the room to place the computer. The computer should be placed against the wall, and the wall facing east where the sun rises should be chosen. Do not place electrical appliances with high heat value around. When placing the main engine, you should choose a position that is conducive to air circulation. There should be a certain space around the top of the chassis, and special attention should be paid to all kinds of air inlets (usually in front of the chassis) and air outlets (behind the chassis) on the chassis. Dust will also have a great adverse effect on heat dissipation, and the surrounding environment should be clean. After a long time of use, dust will generally accumulate on all parts, which will isolate the original from the air, so it is necessary to develop a good habit of cleaning the dust regularly. There is also a lot of dust on the power supply fan and the chassis fan. You can use the gas tiger to remove the dust attached to it in time. These measures can enhance the heat dissipation effect. It's better to turn off the computer when it's not in use. When using the screen saver, don't forget that the power of the computer is not much lower than usual at this time, and the calorific value can not be underestimated. It is best to set the monitor to idle 15-20 minutes before entering the energy-saving mode. You can also set hibernation or pause to memory when the BIOS starts. These measures can save energy and prolong the service life of computers. Of course, both hibernation and pause have their shortcomings, so please set them according to your own situation. In addition, if you are not a super fan of overclocking, please be kind to the frequency! 3. Upgrade the computer fan and chassis or add fans. Motherboards now generally have the function of monitoring the core temperature of CPU. If your CPU core temperature exceeds the ambient temperature too much, you'd better upgrade your CPU fan. The heat dissipation of the hard disk is also very important. You can also assemble a fan for it, but it must be installed firmly, otherwise the vibration will affect the life of the hard disk. Misunderstanding of fan use: some users think that large fans are better. In fact, the radiator effect of large fan is not necessarily good. Although this kind of fan provides long blades and large air circulation per unit area, it does not mean that it has strong ability to take away heat. Because the speed of this kind of fan is usually low, it can't take away the heat in time. Generally speaking, a large chassis is good for heat dissipation, because it allows more air to flow through various components. A well-designed chassis will reserve the position of the front and rear chassis fans. Once this good air flow from bottom to top and from front to back is formed in the chassis, cold air can be supplemented for high calorific value components such as CPU and graphics card in time, and the temperature of CPU and graphics card will be further reduced. 4. Borrowing tools for cooling air-cooled cooling is the most common cooling method, with the highest utilization rate, which belongs to active cooling. This cooling method can meet our usual cooling needs, and the technology is mature and the price is moderate, so it is widely used in the market. The invention is simple in structure, low in price, safe and reliable. However, it also has some shortcomings, such as not being able to lower the temperature below room temperature, and because the rotation of the fan will make noise, if it is improperly installed, it will cause the fan to vibrate, which will damage the computer parts in the long run, and the life of the fan is also limited by time. Water cooling and heat dissipation is to use water instead of air, and take away excess heat through the movement of water and thermal convection between fins. The working principle of the water cooling system is very simple, that is, the water pump pumps water from the reservoir, flows into the heat exchanger covered on the CPU through the water pipe, then comes out from the other port of the heat exchanger and flows back to the water storage tank through the water pipe, so that the heat is continuously circulated and taken away from the surface of the CPU. The whole water cooling system includes heat exchanger, circulation system, water tank, water pump and water. The water cooling system has strong heat dissipation ability, which is very suitable for some overclocking enthusiasts. Its disadvantage is that the water temperature will gradually increase and the heat dissipation effect will become worse and worse because the heat on the heat sink is constantly taken away. Secondly, once there is water leakage or even frost, the consequences are unimaginable. Water cooling safety: When installing, be sure to pay attention to whether the conduit and joint are sealed properly. The principle of liquid cooling heat dissipation and water cooling heat dissipation are the same, and their heat dissipation methods are the same, but the difference is that heat-conducting silicone oil flows in the circulation system instead of water, which has obvious benefits and will not cause damage to computer hardware because of the damage of the circulation system. Aucma liquid-cooled radiator currently on the market belongs to this kind of radiator. 5. The greater the thermal conductivity of radiator material, the stronger its thermal conductivity. Among all kinds of heat conducting materials, silver has the best heat conducting ability, followed by copper, gold and aluminum. Although silver and gold have good thermal conductivity, they are both precious metals, and they are too soft to be processed, so they will not be used as radiators in general. The thermal conductivity of copper is between silver and gold, and copper is cheaper than gold and silver, hard in texture and easy to process and shape, so it has become one of the good materials for casting high-quality radiators. However, it is not that copper has no shortcomings. Under the same volume, metallic copper has high density and high quality. At the same time, it is difficult to manufacture and process, which leads to the relatively high cost of copper radiator, and its price is not affordable for our average consumers. Although the first three materials are good, aluminum radiator is the most common radiator we can see in the market. Because of its low density, light weight, easy molding and low price, aluminum is relatively balanced in all aspects of these four materials. However, because the hardness of pure aluminum is not enough, it is difficult to process it into heat sinks, so manufacturers add other metals to aluminum and make heat-dissipating beer with aluminum alloy. 6, about cooling software There are a lot of software about computer cooling on the Internet. I've used two myself, cpucool and cpuidle. How do you say this? The effect on my computer is very general, but we can't rule out their influence, because different CPU may have different effects on different cooling software. Here are some commonly used software. CPUIdle CPUIdle5.9 comes from Germany and is said to be the first pioneering software for CPU cooling. After many vicissitudes of life, kung fu is already very good. Stable operation is its biggest umbrella. Using it can effectively reduce the temperature of CPU and increase the life and power consumption of CPU. Unlike other power management software, CPUIdle is always working, even if you are using a computer. The software also has the function of optimizing CPU, and only takes up 1%-2% of the system resources at runtime. In addition, the interface of CPUIdle is very refreshing, completely graphical and quite easy to use. WaterfallPro2.99 full version is a very powerful CPU cooling software, which is very suitable for those supercomputer players. It is said that the temperature of CPU can be reduced from 60℃ to about 30℃, and the effect is amazing. It is really a necessary weapon for overclocking families. In addition, it also has powerful functions such as optimizing CPU performance, monitoring CPU usage and power consumption, detecting CPU or motherboard temperature, displaying hard disk space, and giving high temperature alarm. The biggest feature of this software is the unique CPUThrottle design, so it has unique advantages in CPU temperature management compared with other software. Cpucool Cpucool 7.1.1is also authentic German goods. It is quite powerful. In addition to "road" efforts to cool down the CPU, it also has its own unique trick: optimizing SD memory and optimizing CPU. In addition, it can monitor and display motherboard temperature, fan speed and voltage. At present, it has been able to support almost all mainstream chipsets on the market, including Intel, Ali, VIA, AMD and SiS. After CPUCooL runs, it can control the operation of the motherboard and CPU according to the operation of the machine, which provides security for the long-term unattended machine. At the same time, the software also supports remote wake-up of the host. Rain Rain2.0 is also a cooling treasure. It is said to be a simplified and enhanced version of Waterfall. It claims to adopt information technology different from cooling software such as "WaterfallPro" and "CPUIdle", and flaunts itself as "ExtremeCooling! (coolest) ". It can send an HLT instruction to the CPU to make the CPU enter the pause mode, so as to achieve the effect of reducing the temperature, and will not have any impact on the stability of the system. There are some well-known software such as VCool, so I won't go into details.
