How to solve the problem of high computer CPU temperature

Most computer users have encountered the problem of excessive CPU temperature, in the end, how much of the CPU temperature is normal? Today small make up for everyone to clean up the desktop computer and laptop CPU temperature too high solution, take a look!

Cpu

In general, the CPU temperature of 80 degrees or so for normal temperature, if 90-100, this temperature is too high, estimating the CPU itself will appear hardware problems.

Coping strategies of high CPU temperature in desktop computers

1, for the computer chassis to do a simple maintenance, clean up the inside of the chassis dust, especially the CPU, as well as the fan attachment of dust to be carefully cleaned, and then the CPU to reapply silicone.

2, to the CPU cooling fan to add some lubricating oil, improve the performance of the cooling fan, if the cooling fan wind is not strong enough, it is recommended to replace a new cooling capacity of the strong cooling fan.

3. Add an auxiliary external fan to the chassis, or buy a small fan to align the chassis to speed the cooling inside the chassis.

4, check the computer hardware configuration, see if there is any need to upgrade the hardware. When we play online games, the loading speed of the game is very much occupied hardware resources, such as memory, graphics, CPU, etc., so if necessary, you can upgrade these hardware, upgrade, before the old hardware will not be laborious, and will speed up the speed of the game.

High-CPU coping strategies for laptops:

Small series is often used notebook, but also often worry about this, I personally suggest, under the notebook pad two books, and then use the time to put it in the ventilation, the temperature is not very high place.

Here are the views of the Professional staff

Notebook generated heat is its own stability of the largest enemy, if not the heat evacuation, then the long-term work of the notebook in the heat of the consequences is: Light will cause notebook crashes, system crashes, heavy to speed up the aging and end-of-life of the notebook and even burned hardware. So let the notebook as little as possible to produce heat or to allow the notebook to produce the heat in a timely and efficient way out, is the user can not ignore the problem.

However, where the heat comes from, we all know that notebook is also a combination of many electronic components, any electronic components in the use of no doubt will emit heat. CPU is a centralized production of heat, if the CPU is not properly heat treatment may lead to the whole machine scrap (the processor burned), so we will be the thermal performance of the notebook computer is concentrated on the processor. In addition to CPU, optical drive, hard disk, liquid crystal display, GPU, North Bridge chip, battery, memory are heat-producing places. Heat dissipation, in fact, is a heat transfer process, heat transfer, convection, radiation is the three major ways of heat transfer, any idea of cooling technology is led by these three ways, the current notebook cooling technology mainly has air-cooled cooling, heat dissipation plate, heat pipe cooling, and other cooling technology and water-cooled cooling, shell cooling, Hot and cold plate heat dissipation. Wind cooling is the traditional way of cooling, but due to the limitations of notebook space and power consumption, heat pipe cooling technology is widely used in notebook computers.

In the notebook, the large number of heat dissipation mode: fan + heat pipe + heat plate combination.

There is a way to feel your laptop's temperature on the Internet (touch the keyboard and bottom of the laptop directly) you may wish to try, this method is simple and effective: In general, the hands do not feel the temperature of about 25 ℃, there is a feeling of temperature in the 35 ℃ degree or so, warm, that is very warm feeling should be around 45 ℃; Heat but can also continuous contact should be around 55 ℃, feel hot but can endure 35 seconds of temperature due to 70 ℃ around; feel very hot, contact to regret touching it, die do not want to contact the time should be 80 ℃ or so, if there is a smell, the hands of a touch on the smell of burning feathers, quickly wipe point "jing Wanhong" bar, Unfortunately you've been scalded, which is estimated to be above 250 ℃. But we know, even if we feel the bottom of the temperature should be around 55 ℃, then the CPU temperature should be not less than 65 ℃ it. And CPU temperature once more than 75 ℃ and long time work, light is dead, heavy is burnt out. In the process of using a notebook, if it is obvious that the temperature of the keyboard is very high, it is recommended to let your laptop rest.

How to judge your computer heat dissipation performance, I can teach you a way, if you go to buy a new notebook or accompany friends to buy, you can also use this method to determine the thermal performance of a laptop. At the appropriate temperature (about 25 degrees), let the computer execute a number of large programs at the same time (such as 3D games, graphics processing software, media players, etc.), so that the CPU utilization of the computer to 100%, so that memory use more than the size of physical memory, so that the computer run 20-30 minutes Then use your hand to touch the bottom of the notebook and the heat sink, according to the method mentioned above to feel the temperature, to determine the quality of the notebook thermal performance.

Notebook, due to its special nature, such as design, heat dissipation problems, assembly problems, etc., so far, the computer can not carry out the universal DIY, so we can not treat the same as the desktop, summer, you can change a high-power CPU fan, or use liquid cooling device. We only have to work from the outside of the notebook and the way we use it. If your laptop thermal performance is not good, or you need to use the computer for a long time, you can consider to buy an external radiator, the current market of notebook radiators are mainly divided into passive heat and passive heat dissipation type. The passive radiator is made up of a whole piece of metal with high heat conductivity as the base of the notebook,

Close to the notebook to speed up the distribution of heat, cooling effect can not be guaranteed, but also heavier weight, but relatively inexpensive, easy to use, do not consume electricity. Now most of the active radiator, that is, with the active cooling fan,

The cold air is blown to a higher temperature and a heat cycle is formed between the radiator and the notebook to reduce the temperature of the notebook. Recommended to buy a family of active radiator, the effect is better. Of course, the purchase should also consider whether the household or portable, power type, size and so on.

Next I want to talk about the use of notebook, good habits and correct settings can also make the laptop less heat. First of all, we know that the power conversion, nothing more than two go, one is doing work, the other is to generate heat and other ancillary products. We have to reduce the production of heat, there are two ways, the first is to improve the efficiency of work, the second is to directly reduce the consumption of electricity. The first one we do not have the ability to change, only through the continuous improvement of technology can be, but we can reduce the consumption of electricity, in the notebook on the performance of the energy consumption of accessories. CPU frequency reduction technology. We know that Intel SpeedStep technology and AMD powernow! Technology is actually to reduce the CPU power consumption, reduce its calorific value, prolong the use of battery time, so as to enhance the mobile performance of notebook computers.

If you need, you can also use the software to adjust the CPU of your computer to cool down, although I think the effect is not very obvious, but it is still a bit of use.

(1) Liquid crystal display. In fact, the use of liquid crystal displays for a long time will produce a lot of heat, do not believe that the next time you can observe. Like Apple and Sony notebook, even if not used in a short time, the screen brightness will be automatically reduced, so there are two advantages, one is to reduce battery loss, but also to reduce heat, in fact, its essence is the same.

(2) Optical drive. If you use the optical drive, the optical drive is also a concentrated heat of the place, and heat dissipation is not small, there is a light drive system, the temperature of the front of the laptop is still very normal, after the installation has been burned, so I learned the lesson, and then no longer use the optical drive installed system. Now use Ghost to do a mirror on the hard drive, the system (partition) is broken directly restore, fast, and will not produce a lot of heat. In addition, some friends go out when they prefer to use the CD-ROM drive, although the idea is good, but in fact, very unfavorable to the books, I suggest you copy the CD to the hard disk, or make a virtual disc, directly in the hard drive, on the one hand, can reduce the production of heat, but also can increase the life of the optical drive, We know that the optical drive belongs to the more bad parts.

Other accessories I can not say, talk about computer use of some methods, can reduce heat production.

(1) Close some unused external devices and ports. There are a lot of external devices and ports for laptops, such as pcmica devices and shutting down serial, port, IR (IR) ports or Bluetooth ports, etc., by opening the Device Manager, locating the target device, and deactivating it. Not only can save electricity, reduce calorific value also can prolong the service life of the parts ah, three in a swoop.

(2) Close some useless background programs, open Task Manager to end the process, some of the background program is loaded on a boot, you can run Msconfig, the automatic loading of the program to disable, so that the CPU usage and memory usage can be reduced, but also to reduce the production of heat; In addition, try not to use the laptop for a long time, if the implementation of large programs, every 2 hours can let the laptop rest.

(3) The Power management mode of the notebook is set up reasonably. For example, when using an AC adapter or battery power, turn off the monitor, turn off the hard drive, and wait for the system. If you want to leave for a while, immediately back, such as the ThinkPad can hang, the other can be turned off the monitor or set up a blank screensaver, which can save power to reduce heat production, but also eliminates the shutdown of the trouble.

Finally, to talk about the external environment conditions and the use of the habit of the problem, heat dissipation of natural and temperature, so we can create excellent use of the environment is better. Of course I'm talking about the air-conditioning environment. Of course, it's impossible to have air conditioning outdoors, so in the summer, don't use a notebook outdoors if it's not necessary. In addition to the place where the notebook, should try to have enough space to ensure that the surrounding air flow. In peacetime use of the process, many people like to put a laptop on the bed or legs, but summer may be less, this habit is extremely bad. Because the shell generally has a heat sink, if placed on the bed or legs, soft things easy to plug these holes, so that the heat not only can not be distributed out, but also used to heat the laptop, your laptop will be miserable.
