how to stop your laptop overheating

by:Mingfa Tech     2020-01-22
Introduction: Computer (Laptop)
Cooling the cooling of the base CPU (
Central processing unit)
, Otherwise the layman \"brain\" called \"chip\" or laptop is the dilemma that most manufacturers have to face when designing a laptop case (casing)
And choose the right CPU for it.
Cooling is usually performed by a fan and a certain metal conductor, such as copper or aluminum, called a radiator.
CPU and recent GPU (
Graphics processing unit
, \"Connect\" to the metal radiator by conducting thermal grease or compound.
This grease is hot but not hot.
The manufacturer\'s \"trick\" is to use as many small fans and radiators as the CPU allows for heat dissipation.
Vent holes are also cut into the housing, allowing the fan to breathe in cold air from the bottom, forcing it to cross the radiator and blow it out from the side or back, cooling the CPU and GPU.
In a more modern era, copper was used as a conductive metal, liquid was \"pumped\" through the system, and radiators and exhaust outlets were also used like cars.
All of this is to eliminate heat and make the system run faster.
The problem is that over time, dust and other particles can block the system\'s vents, fans and exhaust outlets or radiators, limiting the airflow and cooling.
This is relatively easy to fix by blowing out the vents and fans with air, or by using a brush or earbuds (Q-tip)
Clean up the dust.
Remember: In the computer worldDUST DESTROYS!
However, another hidden problem when the computerlaptops)
Heat or overheat.
They tend to dry hot compounds that conduct heat, causing the system to overheat faster.
Fortunately, most cpu, gpu, and chip manufacturers provide protection for this.
They reduce the operating speed step by step until they finally turn off the CPU, thus shutting down the system.
So if you have a computer system that starts working slower and then turns off without obvious reasons, overheating can be your problem.
The solution to the overheating problem, especially in the laptop, I will show you how to get to the cooling unit, dust it off, replace the thermal grease and assemble everything together again
To prove this, I\'m going to use my friend\'s LG F1 Pro Express dual laptop, which is starting to develop this symptom.
It becomes dull and then suddenly closes for no reason.
This caused him to lose a lot of work and the Outlook PST email file was damaged.
Here, I will show you the solution to this tricky problem step by step.
Interesting technical facts: I took all the photos with my Samsung Galaxy S phone.
Before you start, make sure you have backed up all your data files and you will be able to restore your applications and data if it is unlikely that there will be a problem. (
Tip: Test the data file to make sure the data file is backed up correctly! )
Make sure the backup is completely separate from the laptop, not on the same hard drive, on external devices such as SD/USB or portable drives.
Prepare an area with plenty of light, clean, dry and plenty of space.
Use a towel or soft cloth under the laptop to protect it, because it will lie on the screen for most of the time during the operation.
Make sure that nothing you use, even your clothes, does not generate static electricity.
The process takes about 30 minutes.
Note: This will void your warranty if your laptop still has a warranty.
If still under warranty, ask your supplier to do it for you!
You need the following tools: 1.
Bracket used to prevent the loss of screws. (
The lid of deodorant works very well. )2.
Hot fat or compound.
This should be available in your local computer store or hardware store, otherwise \"Google is your friend \".
A screwdriver that installs the screws on the back of a particular laptop. 4. Earbud (Q-tip)cotton swabs 5.
A wooden tongue-pressing board or any other soft object that scraped off the old hot grease. 6.
Cost of about 30 minutes: a few bucks: huge! (
You will usually replace your laptop as it is not available in the current state. )
Optional: rubber gloves or finger cuff, strip or ground wire. After backing up all the data files and turning off the laptop, unplugging the power and removing the battery, please use some acetone wipesAfter
In the case of LG F1 Pro Express Dual, the battery is released by two clips marked as 1 and 2 in the second picture.
There are 4 screws in the system door to give you access to CPU, GPU, RAM (
Random access memory)
As well as various other components such as real-time clock batteries, modems and cooling units.
Release the battery and remove it completely.
Release four with the correct screwdriver (4)screws.
Once they are removed, put on the stand.
Remove the back cover and put it aside.
You will notice dust on the back cover.
Clean the vents and back cover using brushes and earplugs.
You can now wear rubber gloves and tie the ground/pick-up zone if you wish. I did not.
The easiest way to determine the cooling unit is to look for a fan.
Once you have this, it should be easy to find the screws that fix it.
Carefully remove and put into the bracket.
Gently hold the cooling device and remove it from the laptop.
Try to twist it a little, twist it left and right (Not up and down)
Before lifting it out
It should \"destroy\" any hot grease that is hardened like glue.
This came out at a slight angle.
Remove it slowly and gently as the fan power cord is still attached to the motherboard and needs to be removed before the device is fully extended.
Note: In my case, the CPU came out with the device.
This is unusual and very rare because the CPU is usually locked firmly on the motherboard.
In my case, the hot grease has been completely dry and behaves like \"Putty\" by \"gluing\" the CPU to the heat exchanger \".
The twisting action should \"destroy\" the glue but it is not always possible.
Turn on the CPU socket \"Latch\" and remove the CPU by pressing the edge.
Don\'t touch the pin!
Align the CPU with the socket by matching the marker or pin configuration together.
Press hard to get the CPU in place and lock it in place with a latch.
Use your breath, compressed air, hair dryer or fan to gently blow out the dust from the fan, the housing, the exhaust port and wherever you see it build up.
Clean fan blades using earplugs.
When blowing the fan with air, press and hold the fan so that it does not run in reverse and does not work with the air blowing.
Before blowing out with air again, wipe everything off with a brush for the last time.
Use soft objects like wooden tongue-pressing boards, plastic knives, or old credit cards to scrape old hot grease/compounds from the CPU, GPU, and heat exchanger.
Be gentle and take it slowly as there is no rush and no different angles to try, the dry hot grease should fall off.
Here, you can also remove dry hot grease with an alcohol wipes or soaked with alcoholic earplugs.
Then it will fall off more easily.
If you are going to work and touch the components on the motherboard, I suggest you put on the Strip and rubber gloves.
Place a small piece of thermal fat (
I may be a little too much)
Only on CPU and GPU.
Also do not place anything on the heat exchanger.
All you need to do is place hot grease on one or the other.
Distribute it evenly, very thin on the surface of the CPU/GPUor heat exchanger using a wooden represser, plastic knife or old credit card, which will be in contact with each other.
In this case, the more the better.
Too much thermal grease does not lead to better thermal conductivity, but may even lead to some heat build-up.
Connect the fan power cord.
Replace the heat exchanger and tighten five sets (5)
Fix the screws in place.
Replace the system door and press down gently but firmly until all sides are clipped in place.
Replace four (4)
Tighten the screws.
Replace the battery and make sure the battery is locked in place.
Plug everything you need back into your laptop and turn the device on. Voila!
No longer overheating.
It\'s a miracle that you give your laptop a new life lease!
All in all, some tips and additional resources can help you manage, reduce, and monitor overheating issues with your laptop.
Use a laptop on a hard plane.
Blankets and clothes can clog the vents and reduce air flow.
This helps to further reduce the heat and you can use the laptop cooling pad.
This usually lifts the laptop and has a fan that forces more air to enter from the bottom.
If the laptop suddenly shuts down
Downs also damaged the Outlook PST file, please fix it using SCANPST from MicroSoft.
Different versions of SCANPST for Outlook can be found here: More Outlook repair tools can be found here: if you suspect your system is overheating, this free software program called SPEEDFAN can monitor and record CPU and system temperature.
Keep the laptop cool!
Many people commented that I used too much hot grease (compound)
The amount I use causes overheating.
I don\'t agree with that.
So to provide some kind of proof, I decided to monitor the temperature for a few weeks with SpeedFan v4 anyway. 44.
Then, take the laptop apart again using the recommended alcohol wipe method, clean it up, and replace the hot compound.
I will use a small amount this time.
I don\'t want to put everything together and then monitor the temperature again.
I followed the same process as before and came up with some slight changes.
Documentation of this process.
According to the CPU chip specifications of the Intel Core 2 Duo mobile device LF80537 T5500, the lowest/highest operating temperature (°C)is 0 -100°C.
The maximum operating temperature of the CPU was 65 °c before I started the process.
After I finished the process, the maximum working temperature was 60 °c.
I seem to have applied too many hot compounds but not too much to cause overheating.
Like waste.
It seems that too many hot compounds can cause your system to heat up slightly, and it can cause overheating if it runs close to the maximum allowed temperature.
In my case, it caused a temperature increase of 5 °c, but this is not certain because it is not a controlled situation.
The increase is not enough to cause overheating, but it is enough to infer that too much hot paste will increase the temperature.
Photo contains a stepby-
Step by step guide I made.
Note: I found the alcohol wipes to work badly.
It applied the hot grease all over again, just causing a bigger mess.
This may be due to the fact that the previous thermal grease has dried up and has fallen off well.
This hot grease is wet and sticky.
It\'s too easy to apply.
On the GPU, there are very small resistors or components, wet wipes apply heat transfer oil on them, and then keep getting stuck with them.
If I do this instructions from scratch, I will use less hot grease from the start because it will vary no matter how slight, but I will not wipe it with alcohol.
Update 2013 I have been removing the Intel cpu from my laptop and desktop and replacing the hot compound (grease)
Over the years, we have noticed that thermal grease has been heavily used on older Intel CPUs.
However, this compound is very thin on newer CPUs.
I wonder if there is really more or a small cost saving (tiny)
The amount of compounds between the CPU and the cooler (heat sink)?
Here are Intel\'s own views on how to apply hot grease to the CPU.
What you will read will surprise you because there is no mention of layer thickness, and no mention of spreading it around.
To be honest, it says you mess up everything in the CPU Center and the pressure on the cooler (heat sink)
Thickness is determined on the CPU and all the excess parts are squeezed out.
I think I mentioned something similar in one of my comments.
This information comes directly from the CPU manufacturer and they should know.
In :(
Click \"how to apply TIM\" from the menu \")
I have included some photos on the Intel website for reference.
I also replaced the thermal grease (
If you are from Intel, composite or interface material)
By releasing the cooler on the motherboard (heat sink)
, Clean both surfaces, apply hot grease and replace.
Once you know how, you can replace hot compounds on almost anything.
Update 2014 many people still advise me to use too much hot grease.
I would like to draw the following points to the attention of these people.
I use non-conductive thermal grease.
It does not conduct heat like a conductive thermal grease, but does not damage the part when it comes in contact with the part because it does not conduct electricity.
Cooling is related to eliminating excess heat, so the thermal grease is only part of the solution.
Other parts include radiators, fans, and airflow.
You can have a CPU that doesn\'t apply hot grease well, but there is a great radiator and airflow through it and the system will never overheat.
Here are some links to other resources that I find very helpful in understanding overheating, hot grease, fans and airflow.
I hope this will help you to learn more about the cause of overheating and how to solve the problem.
In the process of writing and expanding this article, I have often been told that I have used too many hot compounds or grease.
Most people who make these statements have no evidence of how much paste needs to be used.
They also did not read the full article and its comments.
I \'ve been doing this since the beginning of 1980s and have never found the number of Tim (
Thermal interface material/compound/grease/paste)
I have caused any problems in the past.
I usually provide a link to the CPU manufacturer\'s Intel website where they explain how to apply TIM.
Intel just states that you apply a spot in the middle to let the pressure of the radiator disperse it.
I also introduced Tom\'s Hardware to people, if there is a deeper analysis of TIM\'s application.
Although Tom\'s Hardware is very thorough on this issue, you will find that it is not completely fair and personal, and the preferences of testers are really prominent.
Like the saying \"it\'s pointless to apply a paste on the entire CPU, and it\'s something of the past,\" because all CPUs have hot spots, these hot spots are usually like sausages in the middle of the CPU from left to right.
However, Tom admitted that it was not that simple in their statement. \"The two pictures below illustrate what a hot spot is, albeit over-simplified way.
Reality is not so simple,
The CPU kernel may be loaded differently and there is still a problem with it on
Chip graphics that may be more active or less active than the processing core.
\"It means we don\'t know where the hot spot is at any time.
Tom even admitted that applying methods was a \"philosophical debate \".
Although Tom had previously said that applying a paste on the whole core was \"meaningless and a thing of the past\", they then discussed the Revoltec thermal grease nano applied with a brush.
Shows a picture in which the entire CPU is shown \"drawing\" with paste, although it is \"meaningless and something of the past \".
Tom said, \"these stickers usually fall at the bottom of our performance chart.
When you try to apply half
Paste the liquid with a brush and usually you get too much, which is not the best option.
\"Then Tom said that communication is tedious and there is a risk of too many applications.
I firmly believe that the amount of freedom is transmitted on the entire surface in contact with the radiator.
The reason for this is that I believe the law that the maximum heat transfer will occur when the maximum area is in contact with the conductive material.
Note: not all TIMs can be spread by hand!
To provide a more credible answer than my experience and opinion, I have collected some \"evidence\" of how chip manufacturers apply TIM\'s picture \". At www. Hard cut
Com they tested the results of the number and method of applying TIM by applying a small point in the middle, a small point in the middle, horizontal lines, parallel lines and distributed on the CPU method.
While the test is not 100% laboratory-proven, it does give the expected results.
In degrees Celsius, the results of the core temperature are as follows: there is a small point in the middle
A small point in the middle
50 horizontal lines-
51 parallel lines
All over-
51. The difference between pasting too much to the right quantity is 1%.
The difference between adding a point in the middle and expanding it is 0.
2%, can be ignored.
Reading this article as their \"correct\" point is also an attempt and error.
Then, I would rather spread the method.
Depending on this information, the type of paste you have, the type of CPU, and the type of radiator that will be used to determine your own ideas.
