Why do some CPUs have a big difference in temperature between computers with the same configuration?

This question is not the same in different situations.

Although the system and fan are the same, but the computer under different loads, the CPU temperature is also different, if you open a lot of big programs, or run games with high requirements for the computer configuration, the CPU temperature will naturally be high.

The temperature of the CPU is also related to the ambient temperature, and the ambient temperature CPU temperature is naturally higher.

Placement of the computer also has an effect, and if the location of your computer has a big impact on heat dissipation, the CPU temperature will also become higher.

And after a long time of booting, the temperature of the CPU will gradually rise.

In addition to the above reasons, there is one main one, because the landlord you did not say the brand of the CPU. Now the CPU of the computer is mainly Inter and AMD, if it is Inter, the temperature will be relatively low, and AMD's CPU is naturally high, which is estimated to be different in design.

In addition, the fan speed is not the most important, the design of the fan itself also determines its heat dissipation performance, such as whether it has a copper core or whether it has a heat sink. How big the fan is: how big the fan is, the shape of the fan blades, and the size of the entire fan and the ventilation structure will affect the heat dissipation performance.

It doesn't just look at whether the fan is new or old and the speed.

Hit more, I hope to solve your problem, can my answer.

First: whether the heat dissipation glue is the same, or the rubbing is the same.

Second: whether the contact between the heat sink and the CPU is good, it generally requires some pressure, not loosening, and loosening cannot achieve the heat dissipation effect.

Third: whether the air flow of the chassis enclosure is the same.

Fourth: the detection software is unreliable.

Fifth: There are good and bad configurations for the same configuration, which is why some people's computers last a long time, and some people break down within a few days.

In the same environment, the temperature of two systems with the same software and hardware should not be so different!

I tested two motherboards today,One is Yingtai's,The CPU temperature is more than 40 when copying the machine,But after replacing the colorful one,The temperature immediately climbed to 73,Except for the motherboard,The rest are the same,The system uses depth XP,So there are some things to consider in comparison!

If it's sure that the configuration is exactly the same, it's a problem with the silicone of the fan. Bad contact with the CPU due to installation issues. You try to take it out, apply the silicone gel and try again.

Power issues, different power consumption for running different programs, or the effects of ventilation and internal dust.

General: The temperature of the CPU is normal 40-50 degrees, and it is about 70 degrees for playing large games.

The graphics card should not exceed 60 degrees.

The hard disk should not exceed 50 degrees, generally not high.

The temperature of the motherboard does not exceed 60 degrees.

If the CPU temperature is high, it will affect the operation of programs, games, etc. The program runs very stuckly in a short period of time, and the frame rate of the game screen is low, which is the feeling that the picture is very slow.

If the CPU temperature remains high for a long time, it will accelerate the aging performance of the CPU, shorten the lifespan, and finally burn out directly.

Generally speaking, it is normal for the computer CPU temperature to be controlled within the range of 30 degrees, what is a temperature rise of 30 degrees, in fact, it is very simple, for example, the room temperature is 25 degrees now, then the temperature of 30 degrees is 55 degrees, that is to say, it is the ideal situation to control the CPU temperature within 55 degrees when the room temperature is 25 degrees.

If the CPU temperature of the computer is high, there is no harm in a short time, but a long time will affect the life of the CPU. So it's better to take a break, it's a little better in winter, the temperature is generally at 30 degrees, so the ambient temperature has a big impact on the CPU temperature.

Extended information: What to do if the CPU temperature is too high.

1. If the CPU temperature is too high on the computer that has been used for a long time, then we can clean the dust. Find a professional to remove the CPU, fan and other parts, clean up the dust of the chassis and hardware, and then apply silicone to the CPU heat dissipation surface, and then install it.

2. Check whether the fan in the case is running normally. If the CPU fan speed is too slow, you can add some lubricating oil to the fan rotation shaft appropriately, but please do not overdo it. If the speed is still too slow, it is recommended to replace the CPU fan with a new one.

3. The CPU temperature is generally above 40 degrees, if cleaning up the dust has no effect, you can open the outer cover of the case, and use an electric fan to blow on the inside of the case to reduce the CPU temperature.

Generally speaking, it is normal for the CPU temperature to be 20-30 degrees higher than the room temperature and will not cause damage to the hardware. When the CPU core exceeds a certain temperature (the CPU surface is generally above 70 degrees at this time), the voltage will be automatically reduced

frequency, effective speed to reduce heat generation, at which point the performance has been compromised. You will feel slow and stuck. If the temperature continues to rise, it will automatically shut down and protect itself.

Note: The internal circuit of the CPU sends a shutdown command Different from the "overheating shutdown" in the COMS settings of the motherboard, it is set by the CPU manufacturer inside the CPU, and it cannot be changed by the user.

It's okay, the motherboard won't shut down until the CPU is 110 degrees.

1.The heat dissipation problem of the CPU fan may be caused by too much accumulated dust, or it may be caused by the silicone falling off, which can be solved by cleaning or applying silicone. If the effect is not obvious, it is recommended to change to a cooling fan.

2.If the temperature does not exceed the standard, if it is acceptable, you may wish to use the frequency reduction software to cool down.

3.For example, various power cables, hard disk cables, and data cables in the chassis are densely packed like spider webs, which will definitely cause ventilation to be blocked, thereby affecting heat dissipation, and can be solved by combing these wires neatly. If there is a vacant space in the case, you can add a 12V case fan.

For a notebook, see if the fan ventilation is unobstructed and whether there is any dust blocking the ventilation duct.

4.It is recommended to install an air duct fan to help dissipate heat, scythes, owls, patriots, etc., must be front or below the air intake, above or behind the air out, otherwise it is easy to cause the hot air back of the graphics card to be blown back and cause the heat island effect to not cool down. At the same time, you can use Game Plus to display temperature, frequency, occupancy, and fan speed in real time on both desktop and in-game.

Can the motherboard adjust the power supply voltage of the CPU? 5200+ core voltage is you can adjust the motherboard power CPU voltage to try!

I've been experiencing this issue for the last month. It can't be a heat dissipation problem. Finally, this trick is done! (The default CPU supply voltage of my ASRock 790G motherboard is ??.)

Reasons why the CPU temperature is too high:

1.Overclocking, which causes the CPU to run at excessively high frequencies.

2.This is very common caused by cooling fans. Such as: the fan is damaged, the fan is aging, and the fan has no oil and the speed is slow.

problems with the radiator. For example, there is too much or too little silicone, and the CPU and the heatsink are not tightly attached.

How to solve the problem that the CPU temperature is too high:

1. Restore the CPU in overclocking to its original state.

2. Test the cooling fan and replace it immediately if it is damaged.

3. Apply the silicone evenly between the CPU and the radiator.

There is also one of the most unfortunate possibilities is that the CPU itself has a physical problem, in which case the CPU can only be replaced.
