It is undeniable that there are some friends who like to live in noise. They like to listen to harsh rock music and turn up the volume. They are super enthusiasts, and their love for overclocking is almost crazy. There are often a dozen fans in the chassis. They love to hear the buzzing sound of the hard disk, and they can sleep peacefully in such "wonderful music".
However, after all, such friends are only a few, and there are more friends who are trying their best to save themselves from endless noise, from the choice of CPU fans to power supply fans, to the point of being almost harsh. In fact, it's not very difficult to build your own silent pc, and it can be easily realized with a few key accessories.
the noise of the computer comes from these aspects: the noise of the power fan, the CPU fan, the chassis fan and the graphics card fan; Noise caused by the rotation of hard disk and optical drive; * * * vibrating sound. The "buzzing" sound we hear when the computer is running is the superposition of these sounds. To effectively reduce the computer noise, it is often impossible to achieve good results by using a silent power supply or a silent CPU fan alone, and it is necessary to solve the problem from each noise source.
1. Elimination of fan noise Power supply fan and CPU fan noise are the main noise sources. The problem of power fan noise is relatively easy to solve, just buy a silent power supply directly.
generally, the noise reduction method of power supply fan is to reduce the fan speed, but if CPU fan reduces the speed, it will inevitably affect the heat dissipation of CPU, so the noise reduction method of CPU mainly lies in the lubrication of bearings and the structural design of fan blades. Because of the high speed of CPU fan, it is still a little difficult for the noise value of CPU fan to reach the level of mute power supply, but we still try to choose the fan with mute function.
of course, it is also a good idea to add some lubricating oil to the fan bearing yourself. The noise generated by the graphics card fan and the chassis fan is relatively small, but too many chassis fans installed in the chassis will also increase the computer noise.
installing as few fans as possible is an effective way to reduce noise, but for those computers that must install multiple chassis fans, you can choose some chassis fans with large diameter and low speed. 2. Noise reduction of hard disk or CD-ROM drive Due to the improvement of hard disk technology, the annoying "giggle" sound when reading and writing data on hard disk is basically inaudible, but the "buzzing" sound of some hard disks is also considerable.
At present, hard disk manufacturers have successively introduced some hard disks with mute concept, such as Seagate hard disks and Samsung V-series hard disks with "liquid bearing" technology, which are all good choices. The noise problem of CD-ROM drive is often difficult to solve, and the noise of some CD-ROM drives even reaches an alarming level. In the words of some friends, reading CD-ROM is "like a helicopter".
Some friends installed software like DVD-ROM Utilities, which effectively reduced the noise of optical drive when using optical drive, mainly when watching DVDs. 3. Elimination of * * * Vibration Noise Not every computer will produce * * * vibration noise. The method of eliminating * * * vibration noise is actually very simple. Just adjust the placement of the chassis or add some soft cushions.
it is not a good idea to add sound-absorbing cotton inside the chassis, which will often affect the heat dissipation of the chassis. The above are just common methods. In fact, if you use your brains more, the noise problem is not a "problem".
2. What should I do if the laptop fan is loud? The fever is also serious
It is necessary to clean the radiator.
1, cleaning. After the notebook has been used for a long time, dust will accumulate in the gap of the radiator because of running the fan all the year round, so it is necessary to open the back plate (some models are very troublesome and need to be completely disassembled to expose the radiator), use a hair dryer or a brush to clean up the dust, disassemble the heat pipe radiator and expose the CPU and graphics card GPU chip.
Apply silicone grease to them again, and then restore the radiator and chassis. After cleaning, the heat dissipation capacity can usually be restored. 2, the dust has been cleaned, and the temperature is still high.
a cooling base can be installed, or an exhaust fan can be installed at the exhaust port, and the installation of the exhaust fan increases the flow rate of air on the radiator fin, with good effect. 3, transform the radiator.
You need hands-on installation ability. On the Internet, you can buy thin heat pipes and connect them to the old ones to increase their heat conduction ability.
3. What should I do if the laptop fan is too loud?
Do it yourself and solve the problem of laptop fan noise. The annoying fan has always upset me recently. How can it make such a loud noise? Is there something wrong with CPU and power supply? Then don't I have to pay for money again? OH,MY GOD！ No way! Do you have such feelings in this situation? Don't worry, first of all, you should be clear that if there is something wrong with the CPU and power supply of the notebook, the product rate of the attack at the fan is very slim, which can be reflected as a black screen, sudden crash and so on, which is somewhat beside the point! Hehe, we are talking about fans here, so how is the noise of fans formed? We know that the internal structure of the notebook is also mechanical, just like a locomotive, it is composed of a drawshaft and a gear, at least at the fan, but its workmanship is more refined! When it comes to bearing noise, what do you usually associate with it-it's time to lubricate it! Yes, as in this case, the noise of the notebook can also be solved by oiling and lubricating! Just compared with mechanical bearings, there is a difference in the choice of lubricating oil. The notebook fan should be selected: clock oil! Let's take a look at the specific operation: first, we should take out the fan and be careful not to scratch the book when opening the shell.
Use a knife to uncover the self-adhesive label on the front of the fan, so that you can see the front bearing of the fan. Some fans have a rubber cover inside, and you have to pry it down to see the bearing. When you open the top cover of the bearing, you can see that there is a snap ring at the top. You can use a pointed tweezers to separate the bayonet, then take it off, and then take out the metal washer and plastic washer one after another.
At this point, we can clearly see the blades of the fan. Hold the blades with your fingers and pull out the motor blades together with the rotor. The protagonist comes on stage, dropping clock oil between the inner and outer rings of the front and rear bearings respectively. Pay attention to the fact that the oil should be completely immersed in the bearings. After the completion, re-insert the shaft into the bearings, install plastic washers, metal washers and snap rings in turn, and finally affix a self-adhesive trademark to return the fan to Zhao. OK, you're done! After the fan bearing has not been lubricated for a long time, the sound has obviously weakened, but it has not completely disappeared, which is not normal! Now your troubles are solved! ? .
4. What's with the loud noise of the computer fan?
The fan belongs to consumables and wearing parts for the computer. There is only a small amount of oil at the grinding shaft, which is slowly consumed in normal operation. The gap at the fan shaft is getting bigger and bigger mixed with dust and the heat emitted by itself, which causes friction vibration. Therefore, it will cause such a result. It is recommended to replace it. Refueling can only solve the temporary problem, and the replacement price is more than 4 to 81. Generally, fans with the worst service life can run normally for more than a year. There are two estimated reasons.
1. The fan is a variable speed fan. When the cpu temperature is high, the rotating speed automatically increases and the noise becomes high. When the landlord just bought it, he was less likely to run a large 3D game.
I didn't feel the sound getting louder until I played. 2. There is a little psychological solution: replace the special mute fan and put the chassis as far away from yourself as possible (it sounds corny and actually works).
5. The laptop fan is loud
If it's a new machine, you don't need to clean it.
It's not the dust (unless you buy a prototype), for the following reasons: 1. The heat dissipation problem of the notebook has always been a headache, because so many things are integrated in such a small volume, so heat dissipation is definitely a problem, and the cpu, graphics card, etc. have to dissipate heat. If you work for a long time, if you play online games every day, the fan will definitely keep turning, and the temperature of the CPU will naturally be high. This is normal.
2. The quality of heat dissipation depends on the working materials of the computer. Good heat conduction and heat dissipation are naturally better. One of the advantages of IBM (now Thinkpad) in those days was that it could dissipate heat.
Dell's is ok, but if you work for a long time, you need to add a radiator or use a fan to blow (pad the computer). 3. Even if you change a fan, the effect is not obvious, which is a common problem.
and it's summer, no matter how hard the fan is, it's noisy, and it's not small. 4, for life, such a load, of course, is detrimental to life, objectively speaking, even if you turn on the phone and do nothing, it is also detrimental to life.
I bought a computer for use. You don't have to worry too much about this, because when your computer expires, it will die. At that time, even if it is not broken, you want to change it yourself.
6. The laptop fan is noisy and still vibrates. How to deal with it?
Analysis of the causes of the loud laptop fan: 1. The coil of the fan is aging and short of oil after being used for too long.
2. Due to improper use, the central shaft is bent due to impact or vibration. 3. Too much dust on the fan or loose fixing screws lead to position deviation.
4. power supply problem. Solution: 1. Check whether the cable in the chassis is reasonable, and rearrange the cable if it touches the computer fan; 2. Tighten the screws for fixing the computer fan to avoid the looseness of the computer fan, resulting in loud sound in the chassis; 3, regularly deal with the dust accumulated in the chassis, especially the dust on the computer fan must be cleaned up, you can use a small soft 4, dismantle yourself, simply put, first pry open the place with the interface on the top of the keyboard, then disassemble all the screws under it, first take down the keyboard, then take down the CD-ROM drive from the back, then take down the hard disk, and you can see the cooling fan, and you will know what the problem is.
5. The broken fan is not a big problem. If you change the fan, it depends on the specific model. The fan is out of oil. Go after the sale within the warranty period, and buy sewing machine oil yourself outside the warranty period.
Extended information: The heat generated by the notebook is the most difficult problem of stability. If the heat is not evacuated in time, the notebook will work at high temperature for a long time, which will cause the notebook to crash, system crash and sudden power failure, and even accelerate the aging and scrapping of the notebook and even burn the hardware. Therefore, it is a big problem that users can't ignore to let the notebook generate as little heat as possible or to let the heat generated by the notebook radiate and conduct out in time and effectively.
