How to reduce the use of noise in notebooks

Notebook in the use of the time will be a number of different degrees of noise, this situation in the notebook load too high will be particularly obvious, long time in such a noisy environment to work will have a certain impact on users. So, how to reduce the noise generated by the notebook, then we introduce some simple small methods.

First of all, we need to know that the main source of notebook noise are the following four aspects: the first is the notebook's cooling fan work generated, the second is the mechanical hard disk reading data generated, the third is the CD-ROM work generated, and the four are the work of various electronic components produced. So for these four factors, the noise of electronic components is relatively weak, we can ignore; the optical drive noise is very large, but the average user does not use it frequently. Therefore, the daily use of notebook noise is mainly caused by the work of fans and mechanical hard drives.

▲ When light is driven, it makes a lot of noise.

Next, analyze how the noise is generated when the notebook is used on a daily basis. The first is the noise of the notebook fan: The fan is the main thermal device of the notebook, the notebook in the work, the internal generated heat will be discharged by the fan, when the internal temperature of the notebook is too high or too long, the use of the fan will be higher, resulting in excessive noise, Thus reducing the internal calorific value of the notebook can effectively reduce the noise generated by the fan.

The second is the noise generated by the mechanical hard disk: Now most of the notebook user configuration of the hard disk is a mechanical hard disk, when the notebook work, the hard disk will be read and written to the data, when the hard disk running load is too large, resulting in the more noise. And the higher the speed of the hard disk, the greater the noise will be generated. Therefore, reducing the running load, or reducing the number of hard drives can reduce the hard drive to use noise.

▲ the hard drive will produce varying degrees of noise when used

After analyzing the source of the noise generated by the notebook, we started to solve the noise problems that bothered our users.

Clean the main thermal area of the Notebook

Method One: Clean the main cooling area of the notebook. Cleaning the dust in the notebook can effectively reduce the calorific value of the notebook, thus reducing the frequency of the fan to achieve noise reduction effect. Since the design of the notebook is different, the design of the outlet and the fan is also in different position, next I take a notebook design that is more common now to explain how to do the cleanup operation.

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

▲ Notebook heat dissipation device and the dust near the outlet are mostly the main cleaning parts.

Because the notebook is in use, the heat mainly relies on the heat dissipation equipment to export, the dust also can have the obvious accumulation. The rest of the circuit board dust is relatively small, clean basic can be ignored.

▲ The dust attached to the outlet area is obvious

▲ The outlet of the notebook after cleaning

A lot of dust gathered on the outlet, we'd better remove the heatsink and clean it up, but it's going to be tricky to grease the CPU and chipset, and some machines don't have a warranty, so the removal will be out of warranty, so we can use the brush to gently stick the dust away, The dust can be blown repeatedly by blowing the surface with air.

▲ the dust accumulation of the fan is also obvious this is the key to clean up the area

▲ Remove the fan by screwing the screws near the fan

▲ The fan interior dust accumulates obviously

▲ the dust on the fan blades also accumulates a lot

A fan is a device that is radiating from a notebook, and if it accumulates too much dust, will certainly affect the thermal performance of the notebook, in the cleaning of the notebook fan to use tweezers and other items to remove the larger dirt folder, and then air blown along the direction of the wind to clean up the internal dust, repeat several times such operations can basically clean a good fan. Fan cleanup can also be removed further, which is more comprehensive.

After cleaning up the notebook inside a lot of refreshing, outlet unobstructed, heat discharged fast, notebook internal heat down, the frequency of the fan work is naturally reduced, the resulting noise will be reduced. Here to remind users, some notebooks can not be completed after the removal of the dust, the need for further dismantling, it is best to get the designated repair site to clean.

Adjust the power management options for notebooks properly

Method Two: Reasonable adjust the notebook power management options. Most notebook manufacturers will install power management software for laptops, users can adjust the performance of the notebook, so as to improve the load on the hard disk and reduce the noise generated by the hard drive.

▲ Lenovo's own power management software

Today I introduced the Lenovo power management with 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, dynamic allocation of CPU work frequency; When the slider is set at the far right end, The CPU is at its maximum operating frequency, and at the far left is the lowest frequency, through which the user can decide whether it is high performance or more comfortable and quiet work.

▲ noise control by configuring CPU performance

In addition to power management, some notebooks also have a key mute function. When the notebook is in a high load state, the fan speed is very high, the noise is very large, through the shortcut keys or some random software, you can instantly let the fan speed down, to achieve the purpose of mute, of course, the frequency of the CPU will inevitably reduce the performance is affected.

▲win7 with power management options

▲ Power Options can be set on your own

Of course, in addition to the power management of various vendors, Windows 7 also has a wealth of power management options, reasonable use can also adjust the performance of the notebook, so as to reduce the noise.

Making full use of third party software to reduce noise

Method Three: Make full use of third party software to reduce noise. For a friend who likes to download must know the Windows Departure mode, in this mode, the notebook off most of the equipment power, but can carry out audio-visual processing, BT download, file copying and other operations, with less power consumption and low noise characteristics, the night hanging a machine BT download will not be very noisy. If you install Master Lu, you can in the energy-saving heating options, into the exit mode, compared to their own settings to be a lot easier.

▲ Master LU opens Windows Exit mode

Besides Master Lu, there are many gadgets that can help us to reduce noise, such as rmclock this small software, it can adjust the CPU voltage, reduce the CPU's working voltage can reduce the calorific value of the CPU, so as to reduce the speed of the fan, because the software is only the CPU operating voltage, The CPU's operating frequency has not changed, so the impact on processor performance is relatively small.

▲ the interface after running Rmclock

▲ Program Selection interface can adjust the performance of notebook

Users who are now using XP also can download the software using silentdrive, this is a special regulation of hard disk noise software, the software has four adjustment options, you can better control the noise of notebook hard disk, but the corresponding different options will also have a different impact on the performance of the hard disk.

▲silentdrive can be used to adjust the performance of the hard disk

SpeedFan This software can also play the effect of noise reduction, it is directly to the computer's fan speed adjustment, so as to achieve a more direct mute effect, the software is mainly to the computer or HTPC to reduce noise processing, notebook calorific value is too large or not recommended, when the fan speed down, Internal heat can not be ruled out in time, may cause the temperature is too high to cause notebook crash or reboot.

The use of software to adjust how much will have a certain impact on the performance of the Notebook, for the general user or try not to use, if the notebook hard drive noise is too large, recommend users to replace the hard drive or install better performance, less noise SSD solid state hard drive. Finally, I would like to remind you notebook users, using software or power management of the notebook to reduce noise will inevitably affect the use of notebook performance, in the work or game time or do not recommend everyone to use.

Summarize

Notebook According to the different configuration, the resulting noise size is not the same, but the main cause of the noise is caused by the fan and hard disk work, the previous 3 methods described, software regulation and the use of power management adjustment methods do not recommend the use of ordinary users, Because in the adjustment process is very likely to modify the settings to other notebooks, causing some unnecessary trouble. In contrast, fan cleaning is the most effective method of noise reduction, this can not only reduce noise, but also reduce the temperature of the notebook to improve the overall performance.
