1. Temperature and voltage issues.
The temperature rise is due to the fact that the heat generated by U is greater than the heat dissipated by the radiator. Once the heat generated and the heat dissipated tend to be balanced, the temperature will no longer rise. The amount of heat generated is determined by the power of U, and the power is proportional to the voltage. Therefore, to control the temperature well, you must control the core voltage of the CPU. But it’s easy to say that. If the voltage is too low, it will cause instability. This contradiction is especially obvious when the overclocking range is large. Many times the system will have a blue screen before the CPU temperature reaches the critical value. At this time, the main culprit affecting system stability is not the temperature but the voltage. Therefore, how to set the voltage is very important during extreme overclocking. If it is set high, the radiator will not be able to withstand it; if it is set low, the U will not be able to withstand it.
2. The temperature measurement methods of various motherboards are different. Even for motherboards of the same brand and model, due to the difference in the distance between the temperature measurement probe and the CPU, the measured temperature will vary greatly. Therefore, it is unscientific to generally say how many temperatures are safe. I think you can run super Pi or 3DMark yourself under relatively high room temperature conditions in the summer, as long as it passes stably, you don’t have to trust the temperature data of the software test too much.
3. What exactly is stability? This has always been a hot topic that everyone likes to discuss.
Computers are electronic products, and the coordination of each component is extremely subtle. No one can say that my computer is absolutely stable. Stability is relative. Overclocking within a reasonable range can resist the catastrophic consequences that most tiny unstable factors may bring; overclocking at the edge of the hardware's limits, a very small current fluctuation may bring about a series of subsequent reactions, which may eventually lead to failure. Turn your screen blue or black:) The question of specifically quantifying how much frequency is stable can only be based on specific situations, and there is no formula that can be applied. It can only rely on experience and personal practice. Therefore, here again I would like to remind some friends who ask "How much can my computer be overclocked?" to try it yourself according to the scientific overclocking steps!
You can usually find out by entering the BIOS.
CPU temperature test
1) Did you use software to test? Personally, I think the most accurate method is Check inside the motherboard. Metal migration will occur when the machine is in a high temperature state for a long time, and your CPU will be hopeless. Then check to see if your CPU is at 100% usage for a long time. Or is it on standby after opening the software? It is almost 100% usage. Use the next anti-virus software to kill the virus. If you don’t want to, try the following method. I hope it is useful to you. You can shut down the computer one hour after it is turned on. First release the static electricity on your body (touch the sewer pipe with your hand), and then touch the CPU radiator to see if it is hot (be careful of burns! Also note that you must unplug the power plug first). If it is not hot, you will be fine.
2) Install testing software, such as EVEREST, SpeedFan, etc. (which can be downloaded online), to conduct comprehensive tests on hardware performance, temperature, etc.
3) You can also check the CPU temperature and fan speed in the motherboard BIOS (see your motherboard manual for the method).
If you find that the temperature of your CPU is close to 110 degrees, then your CPU will go to the west to see the Buddha! Solution:
1) Check whether the fan in the chassis is running normally.
2) Clean the dust in the case (the correct method is to blow the dust with a bicycle pump).
3) Thermal grease must be added between the CPU and the heat sink.
4) Put a drop of sewing machine oil on the cooling fan bearing, which can effectively reduce the noise! Don't drop too much, just one drop will do.
5) If necessary, you can install a high-power CPU fan and purchase a radiator with better heat dissipation effect, such as Kyushu Fengshen.
6) Install a chassis cooling fan (be sure to buy one with double ball bearings).
(There is strong electromagnetic radiation in the chassis, which is harmful to the human body. It is recommended not to open the chassis cover to dissipate heat)
7) Move the host to a well-ventilated place.
High CPU temperature -
The main problem is heat dissipation. I'm afraid there are very few fake ones nowadays. It’s hard to tell if overclocking is being faked. But people with common sense are hard to deceive. There may be more fake cooling racks and fans in bulk boxes. Sometimes the installation is not standardized, and poor contact of the thermal surface is also common. Remove it and inspect it, not only to see the CPU clearly but also to observe the contact between the CPU and the heat sink. Replace with better silver-containing thermal silicone grease. For reference only, the reason why the CPU usage is very high after the computer is turned on normally is probably caused by a certain software that is logged in with the system at the same time. You can open the "System Usage Configuration Tool" program by running and inputting "msconfig". Enter the "Startup" option, then uncheck the suspicious options one by one, then restart the computer, and test repeatedly until you find the software that caused the fault, or use some optimized software to achieve the above purpose. In addition, if the keys in the keyboard are stuck, it may also cause the above-mentioned problems to occur when the computer is turned on. Secondly, viruses, Trojans, Sasser viruses and some spyware can also cause abnormal CPU usage at startup.
The main manifestations of high CPU temperature are:
If the CPU temperature is too high, it will cause the computer to restart automatically. This will cause the machine to age too quickly for a long time; if the CPU temperature is too high, it will instantly damage the computer and burn out the CPU. .
Causes:
1. Caused by overclocking, which is a demanding job for the machine.
2. Caused by electric fans, this is very common in our lives.
For example: the fan is damaged, the fan is aging, the fan has no oil and rotates slowly.
3. Problems between CPU and electric fan.
For example: too much or too little silica gel, the CPU and the electric fan are not tightly connected.
Solution:
For the first one? Either don't overclock, or replace it with a good, high-end electric fan.
The second option is to replace the electric fan.
The third option is to replace the fan.
Last time my classmate cleaned the fan, and then the temperature became higher and higher. I turned on the computer at 50C, played the game at 70-80C, and then it automatically shut down while playing the game. I found that the fan stopped spinning due to him, so I changed it. The problem is solved by getting a fan. I don’t know if LZ is super cool or not. This is also one of the reasons for the high temperature. In addition, the weather is hot now and if the heat dissipation is not good, the CPU temperature will be very high.
PS: Original poster, check if your CPU fan is dusty? How is the fan lubrication condition? The next step is to take it to a repair shop to check whether there is a short circuit on the motherboard and whether the power cords of various accessories are connected incorrectly.
CPU Cooling Tips
1) Check whether the fan in the chassis is running normally.
2) Clean the dust in the case (the correct method is to blow the dust with a bicycle pump).
3) Thermal grease must be added between the CPU and the heat sink.
4) Put a drop of sewing machine oil on the cooling fan bearing, which can effectively reduce the noise! Don't drop too much, just one drop will do.

The fan needs to have a large heat sink (preferably more copper) and a large fan. It has nothing to do with the voltage (different fan impedances lead to different power, and the voltage is 12V), but such a fan may be very expensive because of the price You've probably never considered it.
Let me tell you an experience: Original and authentic CPU fans generally cannot withstand long-term heavy-load CPU workloads (such as playing 3D games for a long time, the presence of some kind of Trojan horse virus, etc.) - this long time, It means that it is longer than a few minutes. Therefore, the fan must be replaced, or your case happens to have a high-power fan on the side panel (not on the power supply!, the power on the side is much greater than that), or you use a floor fan out of the box to always blow.
For AMD, the fan needs to be better. I don’t know if you can afford it. If it were me, I would rather buy a good fan that costs more than 100 yuan, such as the TT brand (you have to look at the heat dissipation specifically) Determine the chip size, type and fan size, don’t be superstitious about brands)
A larger fan will work. My experience is that the fan should be at least as big as that on an ordinary power supply (some power supply fans now have a diameter of 15 cm , not like that, the CPU is not that big and cannot be used), but such fans are often relatively expensive, and few people buy them - I haven’t been to the market for a long time and I don’t know the price, sorry.
I would also like to remind you that a large fan on the side panel of the chassis is necessary, especially on hot days. If not, you must unbox and blow the floor fan, otherwise it will be dangerous under heavy load;
Display It is not good if the card is close to the CPU - if the environment is hot, the CPU heat cannot be dissipated. This is why I say that pure copper is not as effective as a large fan. The fan can blow away the heat, but pure copper can only quickly dissipate the heat from the CPU. When exposed to the environment, the ambient heat inside the chassis can be fatal.
There is another problem with the fan, which is the loudness of the fan. You should also pay attention to this, as the sound is too loud and can cause noise to death
I recommend some CPU temperature control software for you so that you can understand The temperature has changed

Generally, when the CPU temperature reaches 50℃-60℃, it is easy to blue screen and crash. When the CPU temperature exceeds 80℃, it is easy to cause the CPU to burn out! ! !
Now I would like to add a few additional points:
1. Temperature and voltage issues.
The temperature rise is due to the fact that the heat generated by U is greater than the heat dissipated by the radiator. Once the heat generated and the heat dissipated tend to be balanced, the temperature will no longer rise. The amount of heat generated is determined by the power of U, and the power is proportional to the voltage. Therefore, to control the temperature well, you must control the core voltage of the CPU.

3. Regularly clean the CPU cooling fan dust and add lubricating oil to the fan. It is abnormal that your CPU fan speed is around 1600 rpm. The speed is too low. It is normal for the CPU fan speed to be above 2500 rpm. Nowadays, most motherboards are equipped with fan speed detection. When your CPU temperature is too high, the motherboard will increase the fan speed in time, up to 10,000 rpm or more, to ensure that the CPU temperature is kept constant. stability. The fan should be thoroughly cleaned and lubricated, the dust on the radiator should also be cleaned, and a layer of "cooling silicone" should be evenly applied on the protruding parts of the radiator and CPU to make it in close contact with the CPU. After that, as long as the cooling fan speed is normal, the CPU temperature will drop.
Generally speaking, big brand computers from computer companies can be replaced within 7 days! ! The premise is that there are no external or internal injuries! Not opened!
In addition, you can also set the cpu qfan control to disable in the BIOS settings, set the cpu fan to run at full speed, and turn off the intelligent speed adjustment. Check whether the speed has been increased and whether the CPU temperature has been lowered. , if there is no change, you can only replace the fan to avoid burning the CPU.
