How to have a quiet computer _ hardware maintenance

One, the hum of winter
A few days ago really very cold, I do not know whether you found that your usual quiet computer is now turned on when the sound of a bad hum, but after a while, this voice will gradually disappear. What's the reason? In fact, that's probably the trouble with your CPU fan. When the temperature is too low, the fan lubricating oil some solidification, and the combination of dust and oil, make the fan rotating difficult, so that the sound, not only bad, but also may be due to poor lubrication caused fan blocking, burn fan coil, thereby threatening the CPU, the author of the CPU almost killed.
After the machine opened for a period of time, the fan slowly become hot, the viscosity of lubricating oil gradually become smaller, and the fan is well lubricated, so the sound will naturally disappear.
The reason is to know, how to solve this problem? In fact, the ability to do a little bit stronger people can easily solve the problem, that is, to do a clean fan, and refueling (on the fan demolition, cleaning method, please refer to the "Computer" 2000, the 46th issue of "cooling fan maintenance"). Just pay attention to the oil: if you can get the oil that best, the factory has some special lubricant antifreeze performance is very good, evenly coated on the bearing, pay attention to the right amount.
Finally, we can have a quiet winter!
Second, dear, please don't shake
In order to overclocking, do you have a fan with a large wind, good heat dissipation, and a great shock at the same time? The heat dissipation effect is good, but the vibration is also a problem, it makes the noise is irritating, secondly, because of the vibration, the stability of other parts of the work also caused adverse effects, even long-term use will damage the hardware. Since we are diyer, there must be a way to solve it!
Train of thought: someone used to use the rubber band to lift the hard drive to reduce the noise, the author does not agree, because the hard disk is too expensive, if not fixed good, accidentally broken can be a loss, and the hard drive because of vibration caused by the noise is not too big. But the fan is not the same, it is lightweight and not easy to damage, small and will not encounter other things. So I said dry, I removed the fan from the CPU heatsink, with a flexible rope through the four corners of the screw hole, the fan hoist (I do not advocate the use of rubber bands, it is so elastic that the fan is too strong to affect the cooling effect). Note that the position to be adjusted well, to the CPU blowing. For graphics and other devices can also be the same, find another fan and adjust the position, so that it can take into account the graphics card, modem and other equipment, so that the entire chassis also played a good air flow, the entire chassis temperature down, from the computer no longer fever, and no vibration trouble!
Please keep quiet when you are not allowed to speak
Do you like the writer, suffer from the noise of speakers. Here, let's analyze Why:
Double-click the horn symbol in the system tray, turn on the Windows "Volume" property, the CD-ROM option under the "mute" to take the bait, see if the noise disappears, if it is, then the optical drive through the audio line and the sound card connection brings the noise, is generally due to some optical drive interference shielding is not good cause, Then you can mute CD music if you don't listen to CD music often, and even if you mute it, you can play CD music with Super Jie Ba.
After the above action, the author's speaker quiet A little, it seems that there are some problems unresolved. At this time you unplug your speaker and sound card connection, see whether the noise disappears: if disappear, it means that the sound card anti-interference ability is weak, noise signal output, or the connection is too long and anti-interference ability is poor. For the former, generally there is no way, unless you change the sound card filter capacitor, etc. but for the latter, the condition is better to consider the replacement of strong anti-interference ability of the audio line, if you do not want to replace, you can reduce the length of the line, and adjust the location, so that the audio lines as far as possible away from the computer other lines, Another good grounding can also reduce the source of interference.
Such a fiddling, the effect is really good a lot. If unplug the audio line noise still exists, that can only explain your speaker's own quality problem, or a power problem, change a regular point of strip try it.
In short, the author of the Speaker after so small hands, annoying noise basically disappeared.
Postscript:
The noise is solved, the heat dissipation is better, the vibration is gone, just such a small hands-on achievement. In fact, DIY is not complex, do not need how superb skills. As long as you are diligent in thinking, the courage to do, only to pay a small price can solve some seemingly complex problems, is willing to use this small text, and we share.
