Tips for eliminating notebook noise

For the general notebook, in the work, will make some noise, especially in the high load of the working state, the noise will be more intense, but why some notebooks in peacetime use when the noise is also very large?

First of all, we need to know that the noise of the notebook consists mainly of the following sources:

The first is the laptop cooling fan;

The second is mechanical hard disk;

The third is the noise when the optical drive works;

The Forth is the noise from the work of various electronic components.

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

Although we have found the culprits for making noise, mechanical hard drives and fans must be working notebooks to run, so we can only minimize their speed to mute.

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

First, clean up the dust inside the fuselage

When we buy back the notebook for some time, we will find that the noise of the notebook is significantly increased, this should be the most common situation, this is mainly due to the interior of the fuselage gathered too much dust, affecting the heat of the notebook, causing the fan has been at a higher speed caused by increased noise, So as long as the dust inside the notebook to clean up to achieve the goal of noise reduction.

The battery must be taken off.

Before you open the notebook, you must wash your hands before the electrostatic discharge of their own, so as not to harm the internal electronic components, and then the notebook power off, battery down, find the right screwdriver ready to dismantle the machine

Look at the heat sink in the fan at the laptop.

Remove the cleaned part of the shell

In the interior of the notebook, dust is mainly in the cooling part, the rest of the circuit board dust less, no need to clean.

The fan is covered with dust.

Remove the Fan

First the fan down, with the brush to remove large chunks of dust, and then blow the surface of the air repeatedly blowing the dust, if you want to further clean, you can also take apart the fan cleaning.

The vents are jammed.

A lot of dust gathered on the outlet, we'd better remove the thermal components to clean up, but this requires a new to the CPU and chipset on the silicone more trouble, and some machines do not have a warranty, so the demolition will lose warranty, so we can use the brush will be a big piece of dust gently stick away, The dust can be blown repeatedly by blowing the surface with air.

Clean it up.

Installed as is, the notebook is simple to clear the ash to complete

Second, rational use of power management

For notebooks, each manufacturer for their own products provide a powerful power management software, through the regulation of power management software parameters, can achieve a reasonable allocation of notebook performance, so as to control the overall calorific value of the notebook, dynamic adjustment of the notebook fan speed, to achieve the purpose of mute.

Lenovo Notebook Power management for editorial use

The circular icon above, each representing a power management mode, and we can set up each of the modes ourselves.

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

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

CPU frequency can be adjusted in the System configuration Interface

Lenovo's power management has the CPU frequency regulation function, manually, set the CPU's maximum operating frequency, the slider set in the middle, it is automatic adjustment, the system will be based on the extent of the load, the dynamic allocation of CPU work frequency; When the slider is set on the left side, 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 uses the Lenovo V450 with a key mute function, this one-key mute is not the speaker off, but when the notebook is in a high load state, the fan speed is very high, the noise is very large, through the machine body shortcut keys, can instantly let the fan speed down, to achieve the purpose of mute, Of course, the CPU frequency is the lowest, performance will have a loss.

WINDOWS 7 Power Management

Of course, in addition to the power management of various vendors, WINDOWS 7 also has a wealth of power management options, reasonable utilization can also reduce the noise of the notebook.

Master Lu can easily enter the exit mode

We must all know that Windows out of the mode, in this mode, the notebook off most of the equipment power, but can be audio-visual processing, BT download, file copying and other operations, with less noise characteristics of power consumption, the night hanging machine BT will not be very noisy. Of course, enter the departure mode requires some settings, more cumbersome, if you install the master, you can in the energy-saving heating options, into the exit mode. Therefore, the use of good power management will enhance the comfort of our laptops.

Third, the use of Third-party software

Of course, if we have cleaned up the dust in our notebooks and set the power management reasonably, still feel the noise is big, then we can use the third party software to the notebook CPU frequency, the fan speed and the hard disk manual configuration, thus achieves the mute goal, certainly this is the sacrifice notebook performance, More suitable for hanging machine download users.

There are a lot of gadgets on the internet to help us, such as rmclock this small software, although it is older, but the function is really powerful, it can adjust the voltage of the CPU. Generally speaking, CPU calorific value and working voltage into a positive proportional relationship, that is, the higher the CPU working voltage, the more heat emitted. So reduce the working voltage of the CPU can reduce the calorific value of the CPU, so as to reduce the speed of the fan, as a result of the lower voltage, the CPU's 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 software, no need to install, after decompression directly run.

Run Rmclock, this page appears

After running Rmclock, we first select Advanced CPU settings, set the cup as a mobile processor, and then the system prompts you to reboot the Rmclock, we choose Yes, and then Rmclock automatically reboot.

The first step is to set up the mobile processor

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

Third step to adjust the CPU operating voltage

Here, we make sure that the hook in front of the "Auto Adjust intermediate state vids" is already on, and then we just have to tentatively lower the vid voltage of the last "Normal" item to 0.025V, after which the software automatically sets the middle vid. (according to your own CPU options, choose a 0.025 lower than the default setting, do not copy the above image.) )

Fourth Step configuration P-statea

After the DIV is set up, click Application, select My point is "on-demand configuration Performance", "Use p-state conversion" and the corresponding boxes in the tick points, complete the point of application.

Step fifth set the current voltage release scheme

Finally, go back to the "scenario" page and select the scenario you just set up in "current", i.e. "Configure performance on Demand" and set "startup" to "no management." This is because has not been tested, can not be sure just set up the scheme can stabilize the work, if the project can not stabilize the "start", it may lead to boot a load rmclock on the blue screen, only to the Safe mode can be transferred back. It is only after a complete test that the scheme is stable and can be set to start.

In addition to this small software, as well as the software is also very useful, it is directly to the computer's fan speed adjustment, so as to achieve a more direct mute effect, but the software in the edited notebook can not achieve the adjustment of fan speed, and on the desktop is OK.

Four, the ultimate transformation

If you are a hands-on user, the fundamental way to improve your notebook noise is to dissipate heat and replace the mechanical hard drives with SSD solid-state drives. For most students, the replacement of SSDs is a good choice, easy to operate, and the performance of the hard disk is higher than the traditional mechanical hard disk, and improve the heat dissipation is very difficult a scheme, this is not recommended for ordinary users.
