The CPU is overheated, and there is no temperature at all when you touch the fan

Friend, judging from your description, the internal detection temperature is high, and the external feel temperature is low, indicating that the temperature is not transmitted from the inside to the outside.

This situation is generally caused by insufficient contact between the CPU surface and the bottom surface of the heatsink and the heat sink is not transferred out.

There are two ways to try to solve this problem:

1. Reapply silicone grease.

First of all, wipe the previous silicone grease with a paper towel, including the surface of the CPU and the bottom of the heatsink.

Then apply the newly bought silicone grease, and you should also be particular when applying silicone grease, it should be applied more evenly, not too thick, as long as the gap between the CPU and the radiator can be fully filled.

2. In the case of not crushing the CPU, install the radiator tighter, so as not to leave a gap between the CPU and the radiator to affect the heat conduction.

Golden Mango Cooling Professional Team provides you with answers].

1. What brand and model of CPU?

2. What is the power of the power supply?

3. What graphics card is used?

4. What kind of radiator is used?

Put more silicone, and the run-in surface under the fan may not be close to the CPU run-in! Complete.

Upstairs, it's better to go to a repair shop to repair the silicone coating or to have some technology, and you still have to buy it in a computer store.

Apply thermal grease between the CPU and the heat sink, which is generally solved, and if it doesn't work, change the heat sink and add a fan.

Summary. Dear, hello, I'm glad to answer for you, laptop CPU temperature low fan does not turn solution CPU fan power failure. Under normal circumstances, the CPU fan is powered by the motherboard, and the power supply interface can be found by following the fan's cable.

If you find that the cable is loose, you can try to reconnect it and plug it firmly at the interface...CPU fan dust block. If the desktop is used for a long time and is not cleaned, it will cause dust deposits on the CPU fan and block the fan blades.

Remove the CPU fan under and use a brush to clean it、On the fan hinge。 The CPU fan itself is faulty. If the above reasons are ruled out, then it is most likely that the CPU fan has burned out and cannot work.

CPU fan dust block. If the desktop is used for a long time and is not cleaned, it will cause dust deposits on the CPU fan and block the fan blades. Remove the CPU fan under and use a brush to clean it、On the fan hinge。

The CPU fan itself is faulty. If the above reasons are ruled out, then it is most likely that the CPU fan has burned out and cannot work. In this case, you need to purchase a matching CPU fan and reinstall it.

The fan rotates, but when you open the game, the fan rotates slowly, and the frame rate of the game is very low, so the fan rotates very slowly.

No, I have more than a thousand gigabytes of memory, and I won't run out of memory because the game is big.

If the accumulated dust is too large, remove the CPU fan and use a brush to clean it.

Is the power plug loose, not loose is the power supply fan is about to break, change the power supply fan, try to add oil to the power supply fan first, no effect can only change the fan, there are replacement fans for sale. 10 things for quick money or so.

The CPU fan is rotating normally, but the CPU temperature is very high, and the silicone grease at the connection point between the CPU and the fan is probably dry. Re-wipe the silicone grease to see, the silicone grease can not be wiped too much, the kind that bought 1 small piece of 2 fast, squeeze out 2/3 on the CPU, and then evenly wipe it on the CPU, install the fan, and then move left and right a little bit, and finally buckle it. And so it is.

The temperature is about 70 degrees when it is turned on, and it rises to nearly 80 degrees after a while, which means that your heat dissipation is not good, and the original fan will be replaced with a new one after 2 or 3 years, otherwise it is also to add oil to this fan, how to refuel, take the fan out, there is a plastic seal on the back, tear it off, and you will see a rubber stopper. Pick out the plug to see the bearing of the fan, drop 2 points of lubricating oil, glue the seal, turn the fan down, let the oil penetrate in, and it is done.

There are three cases:

1.If the heat sink and CPU are not tightly combined, or the thermally conductive silicone is not good, it is recommended to re-apply the silicone and fix it again.

2.The radiator is broken and there is a blockage in the pipes inside.

3.Motherboard problems, which are rare, but they do exist.

Remove it and touch some thermal grease to try it. Isn't there a good silicone grease to conduct heat with the fan aluminum sheet? Of course, the CPU temperature is high and the fan aluminum temperature is low.

Let's change the detection software, if it is 89 degrees all the time, it may be a detection error.

If the CPU heat sink is pressed, it is recommended that you change the silicone.

Estimated that the CPU and fan are not tightly attached, you can remove the fan and add some thermal conductive silicone to the CPU! Then put it on and try it! This kind of problem is very common!

The fan is blowing inward, and the radiator has to be touched.

Generally, the CPU will shut down for protection before 99 degrees, and this one of yours is a baby.

Presumably a software bug.

The CPU temperature is high, and the fan blades are not hot when you touch them, which is of course, and the radiator is hot if it is hot.

The fan radiator is generally divided into two parts: the fan body and the metal radiator, the general metal radiator is coated with silicone, flat and locked on the CPU, to conduct the heat of the CPU to the metal radiator.

Then put the metal radiator on the tropics through the fan.

Therefore, the plastic fan blades on the general fan will not have too high heat, you can use your hands to touch the metal parts on the heat sink to see if there will be a high heat, if there is no very hot temperature on the metal, it means that your radiator is not installed well, you need to remove and reinstall, silicone grease can not be too thick, you need to wipe the old silicone grease clean when applying silicone grease, and then evenly coat a layer of silicone grease about the thickness of a fingernail, too thick will be effective and will deteriorate after locking, shake the heat sink gently by hand, and there can be no loosening.

If there is a high temperature on the metal, it means that your fan is not airflowing, so the heat cannot be carried away by the fan that needs to be changed at a higher speed or the heat sink with better heat dissipation.

Touch the heatsink and you'll understand = =! The fan generally blows downwards, and you are in the ** 99 that is displayed, software? bios？

There are many possible causes of CPU temperature problems, such as false alarms for temperature measurement, inadequate installation of the heatsink, thermal paste, insufficient power of the heatsink or fan, poor heat dissipation of the host or wind path obstruction, CPU voltage, motherboard problems, ......But it is more common that the quality of the radiator or fan itself is not high.

Here's a complete set of tests and workarounds:

1. Restore the default BIOS of the motherboard, and pay attention to whether the CPU voltage is abnormal. Try changing the BIOS version.

2. Reinstall the radiator to avoid installation problems.

3. The radiator should be evenly and thin. You don't have to buy the kind of ** highest, generally a few dollars a bottle is enough, such as "Star brand DRG-99" This kind of bargain.

4. Pay attention to the heat dissipation of the chassis. For general vertical large chassis, the combination of "front and lower air inlet fan + rear and upper exhaust fan" is the most economical, effective and simple way. This is valid for motherboards, memory, graphics cards, hard drives, and more.

5. False temperature alarms are a common phenomenon. The temperature measurement of hard disks and graphics cards is generally very accurate, but CPUs and motherboards often have problems. After doing the above two points, you can touch the CPU radiator, and sixty or seventy degrees on the copper and aluminum metal must be hot.

There is generally a setting in the motherboard to shut down when the temperature exceeds xx degrees, if it is a false temperature alarm, then turn off this option.

6. Actually, if you are not very particular, then as long as the machine does not crash and restart, don't care about the CPU and motherboard temperature. Of course, there are special ways to test it. If the machine is unharmed for 10-30 minutes, it means that the heat dissipation of your CPU and motherboard has reached the standard.

Note that the CPU and motherboard are very hot during the ORTHOS test, so you need to be prepared. (There are some setup techniques when testing ORTHOS, such as the dual-core CPU should be dual-on and set the kernel correspondence, such as setting a "small amount of FFT" and a higher priority in the software, so as to give the CPU as high a load as possible.) However, it's actually enough to put a lot of pressure on the CPU if you don't set it up, which is definitely not something that the big games can bring.

7. If you don't pass the test in step 6 after you finish the first 5 steps, then solve the problem of the CPU cooler itself. If you want to save money, just see if the fan can be changed alone, and change to a violent fan with high speed (of course, it brings noise problems), and it is not impossible to go down to 5-10 degrees or even more. If it can't be replaced alone, then the entire radiator is replaced, and the more versatile, economical and effective for the general mainstream machine is the "overclocking three-Red Sea-standard version", "Kyushu Fengshen-Bingling 200" and other models, multi-platform general, seventy or eighty yuan **, there are goods everywhere on the market.

Further, models with more than 100 yuan, such as "OC III - Red Sea - Deluxe", "OC III - Red Sea - Extreme Edition", and "Kyushu Fengshen - Bingling 400" are also worth considering.

Too much dust or less thermal grease.

...There is less silicone grease. Do you use the original fan, if it is, there should be no problem, if not, it will not exist.

CPU fans are generally based on power consumption, within a certain range can be automatically adjusted, with the CPU working situation to obtain the minimum power consumption, in July when the weather is hot, the temperature rises quickly, the fan has to run at high speed to overheat, in October the weather is cool, the CPU can stably control the temperature rise at about 45 degrees, and the fan will slow down to reduce power consumption.

If the CPU fan is not a special speed-regulating fan, it is generally not allowed to be interfered with by humans. The motherboard automatically adjusts the speed by adjusting the fan voltage.

It may be that the thermal conductivity between the heat sink and the CPU is not good, remove it, re-coat it on the CPU, don't do too much, just a thin layer, thick is not conducive to heat dissipation, because the silica gel is only to fill the unevenness between the heat sink and the CPU, and its thermal conductivity is actually not as good as direct contact. If you apply too much, the silicone will deteriorate when heated, which will prevent heat dissipation.
