I turned off the fan on the graphics card and the temperature was 140 and it ran for 72 hours withou

It's okay, the temperature is not accurate, the core is measured, and the outside is only 100 at mostYou can't barbecue yet.

Occasionally, I picked up the CPU fan and started to be fine. After a week, the power supply module burst a capacitor. Anyway, keep using.

And then another one exploded. I didn't bother (it's an old computer anyway, so I don't feel bad). After two months, the fourth capacitor was blown out.

And then it couldn't turn on. I thought about it for a while......It wasn't cost-effective to change the motherboard, so I bought a few capacitors and replaced them, well, I've been using it so far, and there is still no problem (of course, I changed the heatsink to a bigger one and used a heat pipe to string it to the chassis).

If you want to think that you are better than me, you can test the length of use. I'll report back to you when the time comes. If you burn it, you burn it, and it seems that you don't care about these two money.

。。。Probably nothing wrong for the time being

However, high temperatures can distort the diodes

Seriously affect life expectancy...

By the way, graphics cards also have self-protection mechanisms

Generally, it will shut down if it exceeds 100 degrees

140 degrees ??? It also runs for 72 hours

That's burned hundreds of times

You blow it, it's impossible to run stably, and it's scrapped if it can run for a week. The upper operating temperature of military capacitors does not exceed 120 degrees.

In a little while, you'll be running out.

Reasons for the high temperature of the graphics card: Generally, the temperature of the graphics card is too high, most of which is due to poor heat dissipation inside the chassis or the slow speed of the graphics card fan. Poor contact between the graphics card chip and the heatsink; The thermal grease on the graphics card chip is missing or dry, and the thermal conductivity is lost; The speed of the cooling fan of the graphics card is not enough, and the power is insufficient; The last case can be caused by a hardware failure inside the graphics card. The solution to the overheating of the graphics card:

1) Observe whether the graphics card cooling fan is running normally, add some lubricating oil to the graphics card cooling fan, if the fan is not damaged, you need to buy a new cooling fan again, if you are not a professional, please remove the graphics card, and directly take it to the IT store to ask someone to replace the fan, which can generally be solved; (2) If the inspection finds that there is poor contact between the graphics card chip and the heat sink, you need to apply thermally conductive silicone between the fan and the graphics card core; (3) If it is due to too much dust inside the computer, there is not enough heat dissipation, we can dust the host, the easiest way is to take a high-power hair dryer to blow hard inside the chassis for a while, or disassemble each accessory, clean up the dust separately, if you are familiar with the computer, it is recommended to remove the internal hardware to clean up the dust; (4) In addition, due to the possible use of inferior chassis caused by the internal heat dissipation air duct is not smooth, we can disassemble the chassis shell or install a convection cooling fan on the chassis to reduce the temperature inside the code core or host, so that the heat emitted by the graphics card can be quickly taken away to strengthen heat dissipation, and if there is no condition, you can directly take the fan to blow the inside of the chassis to strengthen the heat dissipation to solve the high temperature of the graphics card, if the above methods can not effectively reduce the temperature of the graphics card, in most cases, the graphics card is faulty, It is recommended to take it to a professional repair shop for testing.

1.Ash cleaning is important.

Cleaning up the inside of the host is very important, and if too much dust accumulates, it can be a heavy burden on individual electronic components, which is often the culprit of component failure or sudden increase in power consumption.

The heat dissipation device that comes with the graphics card also needs to be cleaned regularly, and the heat release and the airflow from the fan have their own flow tracks, and if it is blocked by dust, the heating problem will not be solved.

2.Utilize silicone grease.

I don't know if you have seen the layer of heat dissipation silicone grease wrapped in the outer layer of the CPU chip, it can be seen everywhere in the computer accessories store, don't underestimate this thin layer of glue-like things, its role is really not small, and it has made great efforts in the thermal conductivity of the chip! In this case, we might as well use it for the graphics card as well. Friends with strong hands-on ability can try to add a layer of thermal grease between the GPU and the heat pipe, especially those old graphics cards that have been depleted of silicone grease, this method has a significant effect.

3.Replacing the radiator is a good idea.

Since the heat dissipation device provided by the original factory is not powerful, then it is good to match it yourself! From air cooling, to water cooling, even extreme gamers can even use liquid nitrogen, you can not only upgrade the cooling fan that comes with the graphics card, but also rely on the higher-end cooling device on the chassis or motherboard.

It is recommended that you go to a computer repair shop to disassemble it, find a professional person to check it for you, clean the hardware configuration, or replace the cooling hardware.

Check to see if you need to clean up dust and apply thermal grease, or if the case has a fan to create a cooling duct.

Solution 1: Reduce the frequency of the graphics card and adjust the fan speed.

Strip, etc., such tools can adjust the graphics card, compatible with NVIDIA graphics cards and ATI graphics cards, more powerful, and more applicable.

Click "System Setting" to enter the overclocking option of the graphics card, and you can see that its frequency is subdivided into standard in the overclocking option

2D (standard 2D), Low Power 3D, Performance

3D (full load 3D) three states, according to the use of the graphics card preset different working frequencies. And we also need to adjust the frequency according to our own usage habits, and try not to affect the performance of the graphics card too much.

The fan speed adjustment function is provided in the fan option, which is also broken down according to the three working states, and the player can adjust it according to the actual usage.

Note: Improving the cooling of your graphics card may affect your graphics card's performance and may also introduce noise.

Solution 2: Reapply silicone grease to the core and install a heat sink on the video memory.

There is another factor that affects heat dissipation efficiency: thermal grease. A layer of thermal grease is applied between the GPU core and the graphics card heatsink, which not only has good thermal conductivity, but also allows the two sides to be in closer contact, so it can improve heat dissipation efficiency.

However, after long-term operation in a high-temperature environment, the silicone grease will gradually "dry" or "harden", resulting in a sharp decrease in its thermal conductivity, and we need to reapply it.

The video memory is equipped with a heat sink, which can further improve the heat dissipation performance, and quickly remove the heat with the help of the airflow generated by the graphics card heat sink, which is also quite cheap, and the retail price is about: 1-2 yuan.

Solution 3: Modify the air duct of the chassis and install a fan of the chassis.

The ideal air duct trend of the computer case is that cold air is drawn from the fan on the front panel, and hot air is extracted from the rear panel of the case, but the mainstream case products on the market basically do not do this, and there are only a handful of products with two case fans preset, and users do not install fans after purchasing these cases. Therefore, we pay attention to the purchase of the chassis and the rationality of the air duct of the chassis, and choose a large-capacity chassis and install a large-diameter silent fan on the back to effectively improve the heat dissipation environment inside the chassis, which is also conducive to the stable operation of the graphics card.

Maybe the heat dissipation is not good? The radius of the original fan is well designed, if the radius of the new fan you buy is too small, it will cause the heat sink to dissipate in time. I used to use a fan on a heatsink and it turned out to be 60+ all the time.

Later, the self-made graphics card fan with an 8cm case fan became about 50.

I don't know what the landlord is, the graphics card, if it's like the current gtx460 Flame God of War, that is, the current high-end graphics card of more than 1000 At this temperature, it's normal, which means that your graphics card has strong performance Or the old original high-end graphics card will also be like this, but if it's a low-end graphics card, there is such a high temperature, most likely it should be a problem with the graphics card, you can clean the graphics card first, it's not good, just go to the computer city to find a computer master to help you take a look.

Play at the right time Don't turn it on and leave it open for days.

Buy a water-cooled circulation system.

Is it desktop.

However, long-term work at high temperature is easy to accelerate aging, but generally more than 70 degrees, you need to pay attention to your heat dissipation performance is not particularly ideal, you need to check whether the radiator, CPU fan, silicon pie glue, etc. are normal; If it exceeds 90 degrees, there must be a problem with CPU heat dissipation at this time, not only the processing performance is seriously reduced, but also there is a blue screen or automatic shutdown function at any time.

Graphics card temperature: more than 70 degrees, especially when this high temperature occurs as soon as the computer is turned on, be sure to check whether the graphics card fan and heat sink are normal, in addition, the dust left by long-term use is also an important cause of high temperature. If the temperature of the graphics card exceeds 90 degrees, please shut it down immediately to prevent the high temperature from burning the core or video memory of the graphics card.

Motherboard temperature: The northbridge chip is the part with the largest amount of heat, but the temperature is much lower than that of the CPU and graphics card, generally not exceeding 50 degrees; If the temperature of the motherboard has exceeded 60 degrees, immediately check whether the heat sheet of the motherboard is loose and whether the wiring in the case is messy and the heat dissipation performance of the case is low.

Hard disk temperature: The temperature of the hard disk is generally below 52 degrees, if the heat dissipation performance of the chassis is very poor, the temperature of the hard disk will exceed 58 degrees, which will cause the hard disk to work very unstable, and may lose data at any time, seriously damaging the service life of the hard disk.

In the end, only one fan needs to be installed on the CPU, and the third generation of Golden Ants is recommended. Around 85. I've used it and it works well.

The temperature is controlled at 30 degrees, and if you can install a fan on your graphics card, install one. However, if the temperature is not high, you can not install it, because there are more fans and too much noise, generally add a power supply fan to install up to 3 fans, cup, graphics card, power supply, if your graphics card does not exceed 60 degrees, there is no need to install it.

There are detailed parameters on this:

No, I've seen your graphics card, it's aluminum or copper, these two pins are the materials used to make the graphics card, and it depends on the scale arrangement of your graphics card's heat dissipation, but the temperature of your graphics card is a little too high, it usually seems to be more than 30 degrees, I don't remember very well, you still go to the Pacific graphics card** then take a look!

The answer from enthusiastic netizens is good.

1. Under normal circumstances, the temperature of the graphics card is 20-50 when it is standby, and (or lower) it is 50-90 in games, which is very normal.

2. If the temperature is high, you need to clean up the wiring in the whole chassis, clean the dust of the graphics card fan, coat the core of the graphics card with silicone grease, and it is best to add a small fan to assist in heat dissipation in the chassis.

3. If it is a laptop, it is recommended to add a cooling pad, or send it to clean up the dust.

1.The temperature of the graphics card is completely normal (I also found that the graphics card was abnormal before, and it is normal to use software to measure and consult people).

3.The monitor is okay to try a data cable, it should have nothing to do with the graphics card and the display, it is a data cable tortuous or aging problem.

4.Memory is the most common problem of the computer, what boot can't be turned on, etc. The slot is broken, and it is normal, just change the slot (you can also use the eraser to try the gold finger of the memory).

5.The weather is hot and it's starting to get hot, try to do the internal hygiene of the case first, and then put it in a ventilated place, which is very important to add.

Since you can see that the fan is not rotating, you should repair or replace it as soon as possible, whether it is a graphics card or a CPU fan, you must take a regular look at it and use a brush to clean up the dust inside, so that the computer will last longer.

There are two possibilities: 1. The CPU temperature is high 2. The system has a virus.

Solution: 1. Replace the exhaust fan 2. Reinstall the system.

Go to the repair shop and take a look, the motherboard burns and you can't do it.

There are more CPU fan thermal conductive glues.

The CPU or graphics card is too hot, and it's basically a broken fan.
