Lenovo laptop dust cleaner. Asus laptop cooler (fan) cleaning master class

How to clean your computer from dust with your own hands. Computers have firmly entered our lives and have become a part of life, leisure, recreation and even earnings for most of the population. Equipment is usually reliable and undemanding in maintenance. However, when a computer malfunctions, the usefulness of our life is also violated. Poor computer performance can be caused by software and hardware failures. Consider hardware failures and, in particular, such a topic as cleaning a computer from dust. Professional system administrators know the requirements for operating servers. And at least once a year they clean their farm from dust. But for ordinary computer owners, cleaning a computer is some kind of exotic while the computer is running.

For normal operation, the computer is equipped with two or more cooling fans. The air that gets inside the system unit leaves the dust contained in it on the electronics, cooling radiators and fans. Over time, heat sinks become clogged with dust and do not perform their functions, which leads to overheating of the computer - the appearance of failures or breakdowns. Dust on the fans leads to excessive noise and also to deterioration of their performance. To avoid such malfunctions, each computer owner should clean the computer from dust at least once a year. Below is a step-by-step instruction for cleaning the system side with compressed air.

Instructions for cleaning the computer from dust

1. Find a source of compressed air. It can be a personal compressor, a compressor of a friend or acquaintance. You can find a source of compressed air at a car service or petrol station. It is acceptable to buy a can of compressed air specifically for purge. It is very convenient to use a blow gun with a long nozzle.

2. Take the system unit out of the working room into the open air and install it securely.

3. Remove the cover from the system unit and open access to the boards.

4. Assess the degree of pollution (the amount of dust inside, on the radiators and power supply).

Dust on the motherboard

5. In case of heavy contamination, immediately blow out dust from all visible places with short blows of air. The recommended pressure applied to the blow gun is 2-3 kg/cm2. During operation, do not touch the electronic parts with the tip of the gun. ATTENTION! Do not spin fans with air, especially on the motherboard and video card, electronics may be damaged due to the induced EMF in the fan windings.

6. In case of light pollution, first blow out the processor heatsink, power supply, video card fans, and then blow out all the dust. An example of purge is shown in the video.

7. Blow out all dust accumulation areas until completely clear.

Motherboard is dust free

8. Wipe with your own hands the outer parts of the blades (blades) of the fans, if dirty, with a cotton swab dipped in alcohol or an alcohol-containing liquid. These contaminants come from smoke, kitchen odors, and sometimes from the user's heavy use of aerosol cosmetics.

SpeedFan 4.52 is a nice set of features for monitoring and managing some PC metrics. In particular, this software product allows you to track the temperature indicators of the processor, power supply, system unit, hard drive, etc., provided that appropriate tracking sensors are available on the computer components. However, the main function of the SpeedFan program is to regulate the speed of rotation of coolers depending on the corresponding temperatures, which allows you to reduce power consumption and background noise during low use of computer resources. At the same time, adjustment is possible both in automatic and in manual mode. Another feature of SpeedFan is the ability to automatically regulate the frequencies (cycles) of the internal processor bus and the PCI bus (but this should be considered a bonus).

The main features of the SpeedFan program:

– Fan speed control.
– Implemented support for SMART technology.
– The user is given the opportunity, at his discretion, to specify the temperature and voltage limit values. In this case, you can set options for the program to act when these limits are reached: launching an external program, displaying a message, sound warning, sending an e-mail message.
– Changing the system bus frequencies on motherboards equipped with frequency generators supported by the program.
– Statistics of parameters taken and recording them in the log.
– Plotting temperature changes, voltages and fan speeds.
– Support for working with HDD on EIDE, SATA and SCSI interfaces.
– Performs web-analysis of the state of hard drives based on data from S.M.A.R.T. using an online database.

Russification of the SpeedFan program:

1. Install the SpeedFan program and run it.
2. In the main window (Readings), click the Configure button, select the Options tab, enter the Language selection list and select Russian.
3. Now SpeedFan will be in Russian!

Most modern laptops, with the exception of some ultrabooks with passively cooled Atom, Celeron, Pentium or Core m processors, have a cooler inside, or even more than one. The very presence of a cooler is understandable - both the processor and the video card require active heat removal. But many manufacturers do not adjust the dependence of the cooler speed on the temperature of the components in the laptop, which leads to the fact that the laptop starts to make noise even with a light load. Taking into account the fact that laptop coolers make loud and unpleasant noise (by the way, the problem is called fan noise), and the temperatures are extremely far from critical, there is a desire to slow down the cooler in order to sit in silence. Of course, you will have to pay for this with increased heating, but usually the game is worth the candle.

I will warn you in advance - there is no universal software method for all laptops. However, there is a theoretical one that works on all models - and from there. The temperature-rpm table itself is usually either hardcoded in the EFI or in the EC register. Therefore, in theory, you can dump the BIOS, find this table, change the values ​​\u200b\u200band flash the BIOS again. However, there are a lot of problems - it is far from always possible to remove the BIOS, and after removing it - to decrypt it. And even after editing it, often users are faced with the fact that the flasher (a program that flashes the BIOS) refuses to “sew” the modified BIOS.

A less universal way, but still supporting quite a lot of laptops, is to use the free Notebook Fan Control program. You just need to download it, run it, select your laptop from the list and either apply the recommended temperature and RPM values, or set your own:


You can see a list of all supported laptops, but even if your model is not there, download it anyway and try the configuration file from other models: manufacturers often use similar coolers.

If, nevertheless, not a single config is suitable, the cooler speed of some laptops (these are almost all Dell and HP models, as well as some others) can be set in the program. To do this, launch it in Sensors mode and click on the cooler icon at the bottom:

If, however, it is impossible to adjust the speed in this program, then, alas, you can write in support of the laptop manufacturer and ask him to change the temperature table, but usually manufacturers do not take such a step. You can also write to the creators of the programs above - they can also help (especially if you send them a bios dump).

Heat buildup can cause any laptop to malfunction. As a rule, if the temperature inside the case rises to high values, then the risk of damage to the internal components of the computer increases significantly. The most common cause of overheating is the accumulation of dust inside the laptop. The electrical components inside the laptop generate heat, so fans are used to cool them down to normal operating temperature to circulate air inside the case. Insufficient cooling can cause overheating inside the case and damage components. Noise from the continuous operation of the fan may indicate that the laptop is heating up due to the accumulation of dust in the vents.

Symptoms of a high temperature and the reasons for its increase

The list below describes some of the problems associated with laptop overheating:

Games stop responding.

Windows OS stops responding during operation.

The laptop's internal fans get louder as they spin faster to cool down.

When starting the laptop, it sometimes stops, Windows does not start, and a black screen appears. Windows usually stops responding at startup.

The mouse and keyboard stop responding.

Windows 10, 8, 7, Vista, XP: The laptop restarts unexpectedly or an error message appears.

Windows 95, 98 and ME: There are frequent reports of critical exceptions, malfunctions, or general protection errors in various programs.

Note.

These errors cannot be predicted. If these errors appear in only one program, it is possible that the problem is related to it, and not to an increase in temperature inside the case.

The list below shows some of the causes of excess heat:

• Dust inside the laptop.

  A new component has been added, such as a hard drive. An additional component causes additional power supply, which leads to the formation of additional heat. Additional heat is also radiated from the new component and raises the temperature inside the case.

  Over time, some cooling fans may slow down or wear out depending on how much you use your laptop.

  High ambient temperature.

Step 1: Remove Dust by Cleaning the Vents

Most laptops have vents to let air into the case. If these openings are clogged, or if the components that generate heat are covered with dust, the fan does not properly cool the hot laptop and overheating may occur. The accumulation of lint and dust particles makes it difficult for air to circulate around the cooling fins, causing the fan to spin at an increased speed and the laptop to heat up. If the ventilation ducts are clogged with dust particles, dust must be removed from the fan and heat shield. This prevents dust from accumulating in the device.

Not necessary open the laptop to remove dust using a can of compressed air.

The following image shows the accumulation of dust inside the laptop, however the dust around the fans and heat shield can be cleared without opening the computer.

Rice. : Dusty

Attention!

Before blowing out the case with compressed air, to avoid damage to the notebook, turn off the power to the notebook and unplug the AC adapter from the electrical outlet.

Use a can of compressed air (you can also use a vacuum cleaner in blow mode or a hair dryer in cold mode, but a can of compressed air is better for this task) to blow out dust and prevent overheating. Removing dust will increase the airflow inside the case, improve cooling, and reduce fan speed.

Cooling fans can be located at different points in the case, depending on the design features of a particular model. Usually under the vents are cooling fins made of copper or ferrous metal.

Note.

Locate and use compressed air to clean all vents on your laptop. In each specific laptop model, the ventilation holes can be located on the side, back or bottom. Some new laptop models may not have air vents.

Use compressed air to blow out the laptop's vents and other openings, such as the intake fan, to circulate the air and keep the components free of dust.

Periodic cleaning and venting of the case will significantly reduce the chance of component failure and prevent your notebook from slowing down.

Step 2: Provide enough space for ventilation

To reduce the chance of overheating, make sure your laptop fans are working properly. The notebook must be adequately ventilated for normal operation. To ensure proper ventilation, do the following:

Place the laptop on a flat, stable surface.

Leave at least 15.25 cm of free space around all fans.

If the laptop is used in areas located at high altitudes (more than 1500 meters), provide additional cooling for the case.

Step 3: Update the BIOS

After the release of the notebook, HP regularly releases BIOS updates and other components. Check for BIOS updates and install them by following the instructions in the HP support document Updating the BIOS .

Step 4: Use HP CoolSense technology

HP CoolSense technology, found in select HP notebooks, combines electronic, software, and mechanical controls to dynamically manage the notebook's temperature. HP CoolSense technology uses the motion sensor built into the notebook to detect whether the notebook is being used on a flat or uneven surface, and then automatically adjusts the computer's performance and fan speed to cool the computer. The HP CoolSense software can be customized to suit your preferences. For more information on this subject, see HP Notebook PCs - HP CoolSense Technology .

Step 5: Set up the laptop in a cooler room

If the laptop overheats, move it to a cooler area. A small decrease in temperature may be sufficient to prevent component failure. Move your laptop to a cooler area in your home or office. If this is not possible, proceed to the next step.

Disassembling an Asus laptop is much easier than analogues from Samsung, Acer and others. You only have to remove the cover without removing the keyboard.
