Especially some computers that have been used for several years are prone to such problems. I can only say that buzzing of computer case is caused by poor heat dissipation of processor. The probability is relatively high, but it is not only one Next article This article briefly presents causes and solutions for computer case whirring.

Reason for computer case humming:

Computer case humming is mostly caused by faulty hardware with heatsinks, such as faulty CPU cooling fans, faulty graphics card cooling fans, and faulty power cooling fans, which can cause computer case to hum. , That's why I can't tell netizens exactly which one, because you still need to open case cover to listen, touch and observe to know exact answer. You can use methods above to find out what hardware is causing your computer case to hum.

1. First, open side cover of computer case, then turn on computer, and then listen with your ears to see which hardware heatsink is responsible for hum. The key is to listen to three main hardware: CPU heatsink, graphics card heatsink, and power supply.

2. If you can't hear well, touch power supply with your hand to check if there is a lot of vibration. You can also turn off CPU fan or graphics card and then turn them on to see if there is a buzz. If not, then we can determine what hardware caused it.

Solution to computer case humming:

If you find a buzzing iron in computer case, it is relatively easy to solve it. If there is a lot of dust on surface of iron, which leads to poor heat dissipation, then we can clean dust on computer and place power supply, processor and video card fan on it .Adding lubricating oil usually solves problem.

Wonderful views of netizens with humming computer cases

If computer case is buzzing due to a bad hardware heatsink and problem persists after dusting, then you have two options, first is that computer is very old, and a little buzzing is normal, Do Not Disturb. If you really can't stand noise, try Taobao and buy cheap equipment.

Tips for netizens: Many homemade players tend to make strange noises on their computers after using them for a certain period of time. There are several situations:

1: If it's a loud "poop" or "buzz" sound

This is sound of a fan. Open case and check if fan screws are loose. Check if fan has slowed down. It is possible that lubricating oil in fan has hardened (especially in winter when weather is too cold). for grease to harden) or no lubricating oil. Add lubricating oil to fan, and normal fan will fail after a long time use. It is better to replace it with a new one that costs 20 or 30 yuan. every.

2: If it's a burning burning sound

This is sound of hard drive being read when hard drive is first turned on.th disk, which is normal, but if sound is loud, it may be that quality of hard disk is relatively low, and sound of a low-quality hard disk will be relatively loud. In other cases, it may happen that hard disk has a small physical bad track due to a large collision. It is recommended to find a professional to check.

3: If yes: long beep

This is a memory issue (usually a blue screen or computer won't start). Remove memory, use an eraser to erase part of golden finger, and then paste it. Clean memory slot if necessary.

4: processor beep

An alarm is issued when CPU temperature exceeds maximum temperature set in BIOS. The CPU temperature is too high. Basically check heat dissipation of fan and case. Turn on CPU to check if CPU is working. The fan does not rotate smoothly or wind is not strong enough Add lubricating oil to CPU Usually fan lasts for a long time If it breaks, it will fail or speed will slow down and you need to replace it with a new fan. Another possibility is that CPU alarm temperature set in BIOS is too low. You can go into boot and press DEL to enter BIOS settings and find "CPU Tempeue" (set CPU alarm sound). Generally, it is set to 60 -70 degrees. Mostly such situations are handled manually. Look.
