The Y470 heat vent does not ventilate but the sound of the fan turning is heard

I used to be Lenovo,Y470 in my hand has countless hands,I've solved more bizarre problems,Your is the problem of the heat sink,It's the curved copper tube next to the fan,There's a liquid for heat dissipation,Because of the long time plus the silicone is dry,The heat sink fails due to the reduction of heat dissipation,That is, it can't be cooled,The liquid inside can't help the CPU cool down。 You go directly to Lenovo after-sales service, let them change it for you, the price will also make it clear to you, you are a consumer machine, warranty 2 years, as long as you have not fallen or other abnormal damage, if the machine has been bought for less than two years and there is no non-damage, you can change it for free, you only need to hand over the machine to him, fill out a form on the line, he will give you a notice to pick up the machine, if the warranty period has passed, you have to pay, it seems to be about 300. Because you want to disassemble the machine, you must ask him to remove the ash by the way when you disassemble it, and let him recoat the silicone on the CPU that is gray and black, and the one that has solidified is also on the heat sink, he is connected to the fan, and change it together, or it will not burn your CPU.

It is estimated that he will call you to do three-dimensional maintenance, depending on yourself, it is still good to do it, it depends on the individual. Finally, remind me,Don't get into the water at ordinary times.,Fall or something.,Or he won't give you protection.,Drain the heat vent when you use it.,Y470This machine,The temperature is a little high.,It's more obvious in summer.。 Your warranty is based on the date of manufacture on the label on the bottom of your machine, unless you can provide a formal invoice, which is estimated to be unacceptable.

That's all I can do to help you, hopefully.

You're sure you have a lot of hair on your hands, and you can feel the breeze sensitively. You change to a big game and play it, you can't play it, there is no wind.

It's sucking air for heat dissipation! The wind goes in.

Is there too much dust, it's time to dust the notebook?

Dear Lenovo users, if your computer has the problem of excessive heating under normal operation, you can follow the following methods to see if you can solve the problem you encounter:

1. Clean up the dust inside the computer, raise the bottom of the notebook or increase the heat dissipation base to maintain a good ventilation environment;

2. Upgrade the anti-virus software of the machine to carry out overall anti-virus and clean up the system garbage;

3. Turn off the startup items that are not commonly used, the method is as follows: press the win+r key combination to call the running window, enter msconfig, click OK, select "startup" to select the card, cancel the loader you don't need to boot, and then OK, you can turn off the boot startup of this program.

4. If the heat dissipation problem of the machine has not been effectively improved after the above operations, it is recommended that you can first try to save important files and reinstall the operating system, if the operating system is still not solved after reinstalling the operating system, it is recommended that you contact the local Lenovo service station and ask the engineer to help you deal with it.

After a long time, there is dust blocking the heat dissipation outlet, disassemble the machine and clean the ash.

Usually normal, why usually?

Y470N is a high-performance notebook, with a powerful CPU and graphics card, but now the laptop cooling technology still has room for upgrade only fan speed, in order to suppress the huge heat generation of Y470N's high-performance configuration, only to increase the fan speed as the last resort.

You should be aware that air movement can cause wind noise, and that it is more noticeable with a fan at a high speed with the same radiator shape.

Personally, I connected variable resistors in series to solve the problem of wind noise, and at the same time, in order not to sacrifice performance, I used a relatively good thermal modification (there are many tools available).

Before the modification, the notebook worked under full working conditions (full load):

No rheostat available, CPU60 75, GPU70 85, obvious noise, fan often rotates, speed above 3500 (standard).

After the modification, the notebook will work under full working conditions (full load):

Without the rheostat, CPU45 55, GPU47 58, the noise is not obvious, the fan rotates frequently, and the speed is about 1500 2000

Enable rheostat, CPU55 63, GPU60 65, no noise, fan often rotates, and the speed is about below 800

The above modifications are all internal modifications, which have not affected the shape and portability of my notebook.

The series variable resistor only solves a noise problem, but if there is no very good heat dissipation performance as a backing, reducing the fan speed to reduce the noise is definitely a death-seeking performance, and after the modification, due to the decrease in fan speed, the start is not frequent, and the battery life has been improved, which is what I am most happy about.

Comes with a fresh screenshot (in normal use).

The high temperature above 80 was left by the fact that I turned off the fan to test the cooling performance.

Hello, when the computer is running normally, the hard disk and fan will produce a certain sound, which is a normal situation. If your machine has abnormal noise and other problems, it is recommended that you back up the important data in your computer and contact the local service station directly for relevant detection and processing. Lenovo service station information inquiry.

The fan turns to produce a small, even sound that can only be felt in a very quiet environment.

If there is uneven noise, it is most likely that there is a problem with the fan.

It's time to clean the radiator.

1. Ash cleaning. After the laptop has been used for a long time, in the gap of the radiator, it will accumulate dust due to the perennial operation of the fan, so you need to open the backplane (some models are very troublesome and need to be completely disassembled to expose the heat dissipation device), use a hair gun or brush, clean up the dust, disassemble the heat pipe radiator, and expose the CPU and graphics card GPU chips. Reapply silicone grease to them, and then restore the radiator and casing, and after cleaning, they can usually restore the heat dissipation capacity of the factory.

2. The dust is cleaned, but the temperature is still high. You can install a cooling base, or install an exhaust fan at the exhaust outlet, and install the exhaust fan to increase the flow rate of air in the radiator fins, and the effect is better.

3. Transform the radiator. Need hands-on installation ability, online, buy a thin sheet heat pipe, and connect it to the old heat pipe to increase the heat pipe conductivity.

Dear Lenovo users, your situation may be caused by excessive dust accumulation inside your computer, you can try to clean up the dust inside the computer, and then observe the operation of the computer.

If it has been used for a long time, it should be blocked by dust, and the heat does not come out, causing the fan to run at full speed.

Go clean up the radiator!

Lenovo's Y-series heat dissipation is not good in the first place. If you feel that the noise of the cooling fan is too loud, you can go to customer service to clean the body and lubricate the fan.

This is not a problem, you just need to open the back cover of the machine, and use a hair dryer to blow on the fan, the fan is loud because you are not dusted for a long time, the fan is loud, and the heat dissipation is not good and may burn the motherboard.

1. The reason why the laptop fan is loud is that the CPU temperature is too high.

Solution: It is a natural situation for the CPU to be too high, as long as the open program window is reduced. However, sometimes the CPU may be occupied by a large number of virus programs, so it is best to upgrade the antivirus software in time to fully detect the system.

When it comes to opening fewer programs, you can remove them from the task manager, where you can see more clearly which ones are larger.

2. The reason why the laptop fan is very loud is that the fan is too dusty.

Solution: Just carefully remove the fan, clean the dust from the fan outlet, and if necessary, apply thermal grease between the CPU and the heat sink. When the fan is rotating, the sound will be loud due to the clogging of dust, and sometimes even flocculent will entangle the fan blades, causing the fan to not work properly.

Laptops are different from desktops, due to limited space, the heat vents are generally designed to be small, and it is very easy to be blocked by dust, especially when using laptops in dusty environments. In general, after 2 to 3 months of use, it is best to remove the fan for dust cleaning, and friends with strong hands-on ability can also add some lubricating oil to the CPU fan regularly, which can also reduce noise.

3. The reason why the laptop fan is loud is that the fan has aged.

Solution: For the fan that has been used for many years and has been aging, it is recommended to replace it directly, and it is not very expensive to buy a new one, if the internal damage of the body is caused by poor heat dissipation, it is not a fan's money can solve it.

Hello, you can improve by:

1. Use disk cleanup to clear the system junk files.

2. Start --- running--- enter msconfig and uncheck all the unnecessary enablement items (such as msn qq, thunderbolt, emulet, virtual optical drive, etc.).

3. Detect and kill viruses and malware.

4. Check whether the heat dissipation vent is clean.

5. Whether the ambient temperature is too high, you can try to raise the laptop to ensure smooth airflow at the bottom and cooperate with heat dissipation.

6. You can consider buying a *** heat dissipation bracket to help the laptop dissipate heat.

7. Close some useless running programs to reduce the burden on the fan.

It's broken, it's too hot, and the motor is going to burn.
