Why does the graphics card make a buzzing sound when it is fully loaded?

When the graphics card is fully loaded, the power demand is greater, so the internal current of the power supply also becomes larger, so the sizzling current sound is completely normal, as long as it is not particularly huge. , the kind that can be heard from a long distance. You can definitely hear it up close. (Recommended Learning: PHPSTORM )

## Of course, the quality of the miscellaneous power supply (online price of less than 150) is relatively poor, so the output is unstable and the regulatory module is poor. If the filtering is poor, the current sound will be loud, so as long as it is not a brand-name power supply, but a big brand, and you spend a certain amount of money to buy it, you can use it with confidence. It is generally recommended that the power supply should be purchased from a big brand that costs at least 200 yuan.

What is the sound of graphics card whistling?

Howling is a professional term in the electronic field, specifically referring to the noise emitted by the inductor due to the harmonics generated by the passing current when the current passes through it. The graphics card also has an inductor, so it will also produce whistling. Of course, the noise caused by the graphics card's fan cannot be called whistling.

Is graphics card whistling a quality issue?

The graphics card howling is normal and not a quality problem, just like the problem of light leakage from the monitor LCD screen, which is a normal phenomenon. The inductor whistling of the graphics card PCB is caused by the vibration noise generated when a large current is filtered by the inductor coil, so it does no harm to the graphics card, nor does it affect the performance and lifespan.

Solution to Graphics Card Howling

I believe that many users will choose to exchange their graphics cards. Graphics card replacement cannot solve the problem of graphics card howling, because this is This is not a quality issue.

So how do we solve the problem of graphics card howling? Let’s take a look at the following points:

1. Since the harmonics generated by the current produce howling through the inductor, it is enough to replace the plug strip with a better one to eliminate the harmonics. It is recommended to use a power purifier. The power strip costs about 200-400 yuan. If you have enough budget, it is recommended to buy another "fever power cord" to match.

2. If you are a friend with strong hands-on skills, it is recommended to disassemble the graphics card, use 406 glue to pour into the gaps of each inductor, and fix the coil, which can solve the problem of graphics card howling. . (406 glue is a transparent, colorless and thin layer. It does not affect the appearance and also has an insulating effect. Use it with confidence. The disassembled graphics card may affect the after-sales service of the graphics card. Please think twice)
