My CPU is 53 degrees when it is turned on, and 79 degrees in less than 3 minutes

Check if the fan is installed or damaged.

I have encountered such a problem, it is the reason of the CPU, I encountered when the CPU segment was a needle, the model is P4 was soldered later, the CPU temperature is very high in less than a few minutes after turning on, if the CPU works at 100% for more than ten minutes, the machine will automatically shut down, and the temperature detection software can see that the CPU temperature at that time is 97 degrees Celsius.

Accuracy is yet to be verified.

I added a fan and replaced the heat sink and the effect was not obvious, but it didn't turn off automatically, and the temperature didn't change much.

I added a pure copper inner heatsink and added a 64-bit CPU fan side blow to the board.

FYI. That's not necessarily the problem.

Check whether the ventilation environment of your case is good, whether there is ash in the case and whether it needs to be cleaned, and see if the CPU fan is running normally, including power supply fan, graphics card fan, etc. These are the problems in general.

One is the fan problem!

Two is your machine super screen! Causes the CPU to overheat! ~~

See if the fan is running normally and whether the fan and CPU are not in good contact!

Remove the CPU fan, wipe the original thermal conductive glue on the contact surface between the heat sink and the CPU, wipe the CPU clean, install the fan, and try to turn it on.

Fans, silicone, check them all out!

Clean up the fan, it should be slow.

1. It may be that there is a problem with the monitoring software, and you can change to other detection software to check the temperature, such as AIDA64, Master Lu and other software. As shown in the figure below, aida64:

2. It may be that there is a problem with the diode that monitors the temperature and the motherboard or CPU needs to be replaced.

It is very likely that there is a problem with your motherboard temperature sensing, and it is impossible for the CPU to be 45 degrees all the time.

You can run a CPU 100% stress test to see if the fan is running normally, and test the temperature at the same time, if the fan is normal, and the temperature has been 45, then the machine is basically fine, but the sensing temperature is not normal, it does not affect the use, you can ignore it.

Excluding software issues, there is only one case where this is the case when the fan comes with an automatic speed control function.

When you open a large program, the temperature of the CPU rises, and the fan automatically increases the number of revolutions, causing your processor to always have a temperature of 45 degrees.

That's the case with a Dell desktop at home, where the temperature is always the same, and I studied it later and realized that this was the case.

This shows that your fan is good and has strong heat dissipation performance.

However, if your temperature is not accurate, you can test it in the temperature test in the performance test to see if the temperature will quickly rise to more than 75 degrees. If not, you won't have any problems with your computer, don't worry, just use it with peace of mind.

On your motherboard, there is a temperature sensor, and there is a temperature sensor on it. If something goes wrong with this head, it will lead to this. If you use Master Lu to measure it, it may not be accurate, it can't measure the temperature and will call the last record.

You can go into the BIOS and look at the temperature to see if there is any change. You will know if there is a problem with the temperature head. There is also a situation where the motherboard temperature is controlled at 45, but the probability is not large.

The motherboard is generally controlled within how many degrees, and he is not an automatic air conditioner after all.

If it's 45 degrees all the time, there is no change I can tell you that the motherboard is broken, no matter how good the fan is, no matter how good the speed control, there will be temperature changes, if there is a warranty, please guarantee it in time, if it is out of warranty, change it to a better point to dissipate heat, so as not to burn the CPU

The CPU temperature is unlikely to remain the same, try another test software, AIDA64 is recommended, if it is still fixed, it should be a problem with the temperature measurement element on the motherboard, some motherboards read the temperature directly from the CPU, and some are read through the temperature measurement IC.

As soon as the machine is turned on, it is 45 degrees, which is definitely abnormal, and there may be a problem with the temperature measuring element. Now in winter, the normal boot into the system should be about the same as the ambient temperature.

The motherboard's CPU probe head is faulty, this head is under your CPU socket, it is used to detect your CPU temperature, and if there is a problem with this head, there will be the problem you mentioned.

In addition to the problem of the motherboard detection chip, it is unwilling to be able to maintain a temperature, such as playing games will increase the temperature. Let's take it apart and take a look.

The sensor is broken and the temperature cannot be detected, so it is always a temperature.

If the temperature doesn't change for a while, there must be a problem with the motherboard's temperature check, but as long as the fan turns, it's generally fine.

You can feel it with your hands, if it hasn't changed, it's normal, and it's probably a sensor problem.

45 degrees is a normal situation, and there is a problem beyond 60 degrees, so you need to pay attention to it.

If it works normally, the temperature sensor should be broken.

The CPU temperature sensor on the motherboard is broken.

The notebook is still desktop, how many years have it been used. It is recommended to change the sound of the wind, or touch some silicone.

It depends on how you use it, and playing some big games might get up quickly.

First of all, you have to tell me what software you use to know your temperature, and tell me which software you use.

45 is good, my boot is 50, whatever, 55.

Tested with AIDA64. Don't use Aunt Lu. Not accurate.

The CPU temperature is slightly high at 47 degrees after powering on, and there are several situations that cause high temperatures:

1. The internal silicone grease of the CPU has dried up, resulting in the heat of its CPU core cannot be transmitted to the outside in time, and the lid needs to be opened to replace the silicone grease.

2. The CPU radiator has low performance, which causes its heat to be unable to be sent away in time, and can only be replaced with a better radiator.

3. The thermal grease material of the CPU is not good, resulting in its heat cannot be transmitted to the heat sink in time, it is recommended to replace it with better silicone grease.

Check the CPU fan and apply silicone grease.

out of sight ，out of mind

Out of sight and out of mind, it's normal for the CPU temperature to be high, and no matter how much you touch the heat sink, you can't touch the temperature of the CPU.

If the CPU fan is not in good contact, just add some thermally conductive silicone.

It's the reason for the thermal grease, the heat does not reach the heat sink, and it can be useful to wipe the previous thermal grease clean and apply a new one.

Some software detects that the temperature is not accurate, you can go into the BIOS to check the temperature.

49 is not high, the highest 80 degrees have to have.

The CPU temperature is too high, and in most cases it is caused by a problem with the CPU fan or silicone grease. Replace the silicone grease again and clean the radiator to solve the problem.

How should thermal grease be applied:

There are two main ways to apply it now:

1. Squeeze silicone grease in the center of the CPU surface, and then put a rubber sleeve on your finger (anti-impurities, the rubber sleeve is included), and apply the silicone grease evenly.

2. Squeeze a little silicone grease in the center of the CPU surface, then press the radiator, and rotate according to the direction indicated by the arrow to ensure that the silicone grease expands evenly and there are no bubbles.

After half a year or more of use, most ordinary thermal grease will "dry" or "harden", which greatly affects the heat dissipation effect. Therefore, to ensure that the system works stably for a long time, it is also necessary to clean and reapply the silicone grease regularly.

The CPU with 4 cores will generate slightly more heat, but if your CPU usually has 88 degrees, then you need to pay attention, this is still very dangerous. The temperature is too high.

The loud fan rotation is because the machine has detected that the temperature of your Peixiao CPU is too high, so it is normal to increase the heat dissipation by speeding up the fan speed.

You should disassemble the case, and then check whether there is no tight connection between the heatsink of the Changzhong Xun CPU and the CPU, or there is no silicone grease in the middle, which causes poor heat dissipation. If yes, you can reapply the silicone grease and keep them in close contact. If it still doesn't work and the temperature is still high, then you can see if your fan is turning properly.

If the fan is not the original one, then you may need to replace the fan with better heat dissipation.
