How to completely eliminate notebook noise

First of all, we need to know that the noise of notebooks mainly includes the following sources:

The first is the cooling fan of the notebook;

The second is mechanical hard disk;

The third is the noise when the optical drive is working;

The forth is the noise emitted by various electronic components when working.

So for these four factors, electronic components of the noise is relatively weak, we ignore, the optical drive noise is very large, but not often used, so also out, then only the notebook fan and mechanical hard disk noise, which is the main source of noise notebook.

Although we have found the culprit of making noise, but the mechanical hard disk and the fan must have to work the notebook to run, then we only try to reduce their speed to achieve quiet.

For fans, it is an important part of the notebook cooling components, the higher the speed indicates that the notebook inside more heat is brought out, and the source of the heat is the notebook internal circuit components work is generated, when these components for the notebook to provide higher performance, they emit more heat, The higher the fan speed, the greater the noise. So the noise and notebook performance is the opposite of the relationship, for the mechanical hard disk is the same, 5400 RPM drive noise will be less than 7200 rpm, the same performance is also low and 7200 rpm. Then the next method is mainly through reasonable configuration to balance the relationship between performance and noise, to achieve the purpose of noise reduction.

　　First, clean the inside of the body dust

When we buy back the use of the notebook for a period of time, we will find that the noise of the notebook increased significantly, this should be the most common situation, this is mainly due to the internal body gathered too much dust, affecting the cooling of the notebook, causing the fan has been at a higher speed resulting in increased noise, So as long as the dust inside the notebook can be cleaned to achieve the purpose of noise reduction.

The batteries must be taken away.

Before unpacking the notebook, be sure to wash your hands before the discharge of their own static, so as not to harm the internal electronic components, and then cut off the laptop power, the battery to take down, find the right screwdriver ready to dismantle the machine

Look at the cooling holes in the laptop fan, it's covered with dust.

Remove the cleaned part of the shell

Inside the notebook, the dust is mainly in the heat dissipation part, the rest of the circuit board dust is relatively small, no need to clean up.

The fan is covered with dust.

Remove the Fan

First, the fan is removed, with a brush first to remove large pieces of dust, and then with the air blowing repeatedly blowing the surface of the dust, if you want to further clean, you can also take apart the fan clean.

The vents are blocked.

A lot of dust gathered on the air outlet, we'd better remove the thermal components to clean up, but this need to new to the CPU and chipset coated silica is troublesome, and some machines have not yet warranty period, so demolition will lose warranty, so we can first use a brush to gently glue the bulk of the dust away, The dust can be blown off the surface repeatedly with the gas blowing.

Clean up.

Installed as is, notebook simple ash finish

　　Second, the rational use of power management

For notebooks, each manufacturer for their own products provide a powerful power management software, by adjusting the parameters of the power management software, can achieve a reasonable distribution of notebook performance, so as to control the overall heat of the notebook, dynamically adjust the fan speed of the notebook, to achieve the purpose of silence.

Editor used by Lenovo Notebook power management

The circular icon above, each of which represents a power management mode, and we can set each mode on its own.

In the set interface, we can adjust the brightness of the display

In the Setup interface, the first thing to see is the display Setup interface, where we can change the screen brightness, the time to turn off the monitor, and so on, there is no direct connection to the noise reduction we are talking about today, and the next interface is very important.

CPU frequency can be adjusted at the System configuration Interface

Lenovo's power management with CPU frequency regulation function, can be manually, set the maximum operating frequency of the CPU, the slider is set in the middle, it is automatic adjustment, the system will dynamically allocate the operating frequency of the CPU according to the degree of load; When the slider is set at the leftmost end, the CPU is at the highest operating frequency; Setting at the far right is working at the lowest frequency, and with this configuration, users can decide for themselves whether they want high performance or more comfortable and quiet work.

In addition to power management, the editor used this Lenovo V450 also has a button mute function, this one-button mute is not the speaker off, but when the notebook is in high load state, the fan speed is high, the noise is very large, through the machine body shortcut keys, you can instantly let the fan speed down, to achieve the purpose of silence, Of course, the CPU frequency is the lowest, the performance will be lost.

WINDOWS 7 Power Management

Of course, in addition to the power management of each vendor, WINDOWS 7 also has a wealth of power management options, reasonable use can also reduce the noise of the notebook.

Lu Master can easily enter the leave mode

We must all know the windows of the left mode, in this mode, the notebook off most of the device's power, but can be audio-visual processing, BT download, file copying and other operations, with low power consumption of noise characteristics, the night hang BT will not be very noisy. Of course, entering the left mode requires some settings, more cumbersome, if you installed LU master, you can in the energy-saving heating option, enter the left mode. So the use of good power management will improve the comfort of our use of notebooks.

　　Iii. using third-party software

Of course, if we have cleaned up the dust of the notebook and reasonably set the power management, still feel the noise is large, then we can use third-party software to the notebook CPU frequency, fan speed and hard disk manual configuration, so as to achieve the purpose of mute, of course, this is the sacrifice of notebook performance, Compare the users who are suitable for the hang-up download.

On the internet there are many gadgets can help us, such as rmclock this small software, although it is relatively old, but the function is really powerful, it can adjust the voltage of the CPU. Generally speaking, the CPU calorific value and the working voltage in a positive proportional relationship, that is, the higher the CPU operating voltage, the more heat emitted. So lower CPU operating voltage can reduce the heat of the CPU, so as to reduce the fan speed, because the lower the voltage, the CPU operating frequency has not changed, so the performance of the CPU is guaranteed.

We first download rmclock, this software is a generation of pure green small software, without installation, decompression and directly run.

Run Rmclock, this page appears

After running Rmclock, we first select the Advanced CPU setting, set the cup as the mobile processor, and then prompt to restart the rmclock, we select Yes, and then rmclock restart automatically.

The first step is to set up the mobile processor

The second step into the solution selection interface to set the processor to move, Rmclock automatic restart, we select "scheme" on the left side of the interface, you can jump to the scheme selection screen, here, we will be able to set the operating voltage of the CPU, wherein the FID is the CPU dynamic FM frequency multiplier, The vid is the voltage that corresponds to each frequency multiplier.

The third step is to adjust the CPU operating voltage

Here, we make sure that the "auto-adjust intermediate state vids" front hook has been hit, and then we just need to set the last "Normal" of the vid voltage tentatively reduced by 0.025V, after which the software automatically sets the intermediate vid. (Please choose a file that is 0.025 lower than the default setting according to your own CPU options, do not copy the above image.) )

Fourth Step configuration P-statea

After you have set up the Div, click Apply, select My point is "configure performance on Demand", the "use p-state conversion" and the corresponding box tick all points, complete the post-point application.

Fifth Step setting current voltage drop scheme

Finally, go back to the "Scenarios" page and select the scenario you just set up in "current", which is "Configure performance on Demand" and set startup to "not managed". This is because has not been tested, not sure just set the solution can be stable work, if not stable work of the scheme set to "start", then may lead to a load rmclock on the blue screen, only in safe mode can be transferred back. It is only after a complete test that it is certain that the scheme is stable and can be set to "start".

In addition to this little software, like SpeedFan, this software is also very useful, it is directly on the computer's fan speed adjustment, so as to achieve a more direct mute effect, but this software in the editing notebook can not achieve the fan speed adjustment, but on the desktop.

　　Four, the ultimate transformation

If you are a hands-on user, the fundamental way to improve your notebook's noise is to heat up and replace your mechanical hard drive with an SSD. For most students, replacing the SSD is a good choice, the operation is relatively simple, and the performance of the hard disk is higher than the traditional mechanical hard disk, and improve the heat dissipation is very difficult to use a solution, it is not recommended for ordinary users.
