What about the loud noise in the notebook

　　I believe many people have heard that laptops are less noisy than desktops, but why? and different brands of different types of notebook noise size is also different, this is why?

For notebooks, fans, hard drives, and optical drives are noise sources, fortunately, due to flash memory and the rise of the network, the use of CD-ROM has been reduced, many books have said goodbye to it, and, again, the optical drive belongs to the passive noise, as long as it is not used, it is basically in a silent state, therefore, the noise of the CD-ROM is In the face of the fan and hard drive noise, manufacturers adopt those ways to reduce noise?

　　Fan: As long as the heat not noise

In many people's view, heat dissipation and noise is a pair of irreconcilable contradictions, because want to heat good, the fan will be big, but also increase the noise. This is a fallacy, in fact, a well-designed notebook, not only to have a good cooling, but also require the fan to work as much as possible to reduce noise, otherwise, a loud noise of the computer, performance, and then "cool" also no one has the courage to use it. As a result, today's notebook fans are all using noise reduction design.

1, intelligent control speed + seismic noise reduction

Many users will find that when playing the game, The notebook fan will emit "whistling" sound, and in the system desktop does not run the program will be very quiet. In fact, this is the Intelligent fan control system, at low temperature, the slow rotating fan makes the noise greatly reduced, only when the CPU, graphics and other components of the temperature rise, the noise will increase with the fan speed.

And some of the noise reduction measures may be overlooked, for example, in many notebook fans and radiator parts, are affixed with sponge bar, this simple and pleasing design is also to reduce noise. When the fan is rotating at high speed, it is inevitable that there will be some vibration, not only causing noise, but also damage the heatsink and shell. It is relying on these sponge strips, the heatsink and fan firmly locked, and absorb the fan vibration generated by the energy, so that the notebook more muted.

2. "Eagle Wing" fan is as quiet as an owl

While the above measures reduce noise while the fan is running at low speed, consumers are picky, especially the "Night owl" users who seek inspiration in quiet evenings, and the sudden noise may upset the "Nite Owl", so how do you make the fan run at a high speed with low noise?

The "Eagle Wing" fan used in some notebooks gives us a good answer, what is the difference between this fan and the traditional fan? From the shape of the fan blade, we can see intuitively that the fan blades are much denser than those in the ordinary notebooks, and the ambient air around each blade is smaller when it rotates, Blades and plastic rings firmly fixed, so that, when the fan is rotating, it is not easy because of the impact of airflow caused by the fan blade deformation, trembling and so on, so the fan blade itself noise greatly reduced. And in the design of the blade, "Eagle Wing" fan also has a special place, the fan blade is not as vertical as the traditional blades, but there is a certain angle, such a design, more in line with the aerodynamic principle, can reduce the interference between the airflow, so that the wind of the notebook is smaller.

3, no fan design

What is the ultimate fan mute? That is, of course, no fan, no fan parts, naturally there is no noise. Some low-power laptops, such as some lightweight books and netbooks have achieved the ultimate mute target, but Low-power processor performance will be poor, this kind of computer games will be "collapsed", and the entire fuselage will be warm, it is comfortable ears, pain in both hands. Of course, for laptops with low performance requirements, laptops with this design will have no side effects.

　　Hard drive: Slowly "quiet" heart work

Relatively speaking, the focus on the hard drive noise is less, after all, its voice than the fan to a little bit, and, again, the same purring, the outside world may not be able to tell whether the fan or hard drive noise, so, all the guilt is added to the fan. In fact, many of today's notebooks, especially the use of high speed hard books or netbooks, small and thin notebook, the noise of its hard drive is not inferior to the low speed state of the fan noise, especially when reading the data "click" Sound, more like the late night in the endless wave, enough to make you yell: "Shut up!"

1, isolation is the foundation of earthquake resistance

Noise reduction technology is similar, sponge and rubber not only for the fan noise reduction, for hard drive noise reduction, the same effective. For example, some notebook hard drives do not use the public version of the notebook hard drive bracket design, instead, it is wrapped in a special sponge and rubber material, designed not only to improve the survivability of the hard drive under impact, but also to prevent the noise and vibration of the notebook from being transmitted to the casing, causing the chassis to resonate or "amplify" And make the noise expand further.

2, the ultimate solution SSD

For the notebook noise reduction design, traditional hard disk or a fairly contradictory parts, want to improve performance, it is necessary to improve the speed, and improve the speed, will increase the noise. Performance and noise performance, so tangled up, become a traditional hard disk difficult to break the cycle. However, the presence of SSD solid-state drives, not only completely solve the hard disk noise problem, but also reduce the overall weight of the notebook, solid-state hard disk is a pure electronic structure, no movement structure, so that, in the work, will not produce noise, at the same time, its performance is quite excellent (but long read and write fragmented files will reduce life). It can be said that, in addition to the price, the SSD almost everything is satisfactory, however, the electronic equipment this thing, its price decline and popularization speed, often unpredictable. When it comes to popularity, we don't have to talk about the noise of hard drives.

　　Summarize:

For the noise of the feeling, everyone is not the same, if you are in the daytime more noisy place to use, may not feel the existence of noise, conversely, if you have in the dead of night, the habit of using a notebook, the noise requirements can be high. Therefore, for "Night Owl" users, in the purchase of notebooks, must pay more attention to its noise performance, suggested that "night owl" in accordance with the several aspects described in this article carefully screened (SSD hard drives excepted). At the very least, when you buy, you should not hear any noticeable noise from your ears when you reach the 30cm of your notebook, so that you will be eligible for a long night.
