1. The buzzing sound in winter
It was really cold a few days ago. I wonder if you noticed that your computer, which was usually quiet, now makes an unpleasant buzzing sound when it is turned on, but after a while, this sound will gradually disappear. What is the reason? In fact, it is probably the fault of your CPU fan. When the temperature is too low, the lubricant of the fan is somewhat solidified, and the combined influence of dust and oil deficiency makes it difficult for the fan to rotate, so this sound is produced. It is not only unpleasant, but also may cause the fan to be blocked and the fan coil is burned down, which threatens the CPU, and the author's CPU is almost killed.
After the machine is turned on for a period of time, the fan slowly becomes hot, the viscosity of the lubricant gradually becomes smaller, and the fan is well lubricated, so this sound naturally disappears.
The reason is that I know, how to solve this problem? In fact, people with slightly stronger hands-on skills can easily solve this problem, that is, clean the fan and refuel (for the removal of the fan, please refer to the 2000 Issue 46 of the Computer Newspaper "Repair of the Cooling Fan"). Just pay attention to the oil: If you can get engine oil, it is best. Some special lubricating oils in the factory have very good anti-freeze performance. They are evenly applied to the bearings, and pay attention to the appropriate amount.
Finally, we can have a quiet winter!
2. Dear, please don’t shake again
In order to overclock, do you have a fan that has strong wind power, good heat dissipation, and also has a lot of vibration? The heat dissipation effect is good, but vibration is also a problem. First, the noise is irritating; second, due to the large vibration, it also has adverse effects on the stable work of other components, and may even damage the hardware after long-term use. Since we are DIYer, there must be a solution!
Idea: Someone once hung up the hard disk with a rubber band to reduce noise. The author does not agree with this, because the hard disk is too expensive after all. If it is not fixed well, it will be a big loss if it is accidentally broken. Besides, the noise caused by the vibration of the hard disk is not too high. But the fan is different. It is lightweight and not easy to damage, and it will not touch anything else when it is small. So I took the fan off the CPU heat sink, used a elastic thin rope to pass through the screw holes in the four corners, and lifted the fan (I don't advocate using rubber bands, it is so elastic that the fan moves too hard that it affects the heat dissipation effect). Pay attention to adjusting the orientation and blowing towards the CPU. You can also do the same for graphics cards and other equipment. Find another fan and adjust the orientation so that it can take into account graphics cards and Modem and other equipment. This will also play a good air flow role in the entire chassis, reducing the temperature of the entire chassis. From then on, the computer will no longer have a fever and will not have any worries about vibration!
3. Please stay quiet when you are not allowed to speak
Are you suffering from speaker noise like me? Come on, let's analyze the reasons together:
Double-click the speaker symbol in the system tray, open the Windows "Volume" property, and hook the "Mute" under the CD-ROM option to see if the noise disappears. If so, then the optical drive causes noise through the connection between the audio cable and the sound card. Generally, it is caused by the poor shielding of interference by some optical drives. If you do not listen to CD music frequently, you can mute the CD music, and even if it is muted, you can still play CD music with Super Remote.
After the above actions, my speakers became a little quieter, and it seems that some problems have not been solved. At this time, unplug the connection between your speaker and the sound card to see if the noise disappears: if it disappears, it means that the sound card has weak anti-interference ability, has no noise signal output, or the connection is too long and has poor anti-interference ability. For the former, there is generally no way, unless you change the filter capacitor of the sound card, etc.; but for the latter, if the conditions are good, you can consider replacing the audio cable with strong anti-interference ability. If you don’t want to replace it, you can also reduce the length of the connection and adjust the orientation to keep the audio cable as far away as possible from other connections on the computer, which can reduce interference. In addition, good grounding can also reduce interference sources.
After fiddling with this, the effect was really much better. If the noise still exists when unplugging the audio cable, it can only mean that there is a problem with the quality of your speaker itself or the power supply problem. Please try a more regular plug-in board.
In short, after such a small effort, the annoying noise basically disappeared.
Postscript:
The noise was solved, the heat dissipation was better, and the vibration was gone, just the result of such a small action. In fact, DIY is not complicated and does not require very superb skills. As long as you are diligent in thinking and brave in taking action, you only need to pay a small price to solve some seemingly complex problems. I hope to use this short article to encourage you.
