I changed the thermal paste and the laptop still gets hot. “Help, the laptop is heating up! Cleaning and replacing thermal paste did not lead to anything...” Or my personal experience with thermal paste. Causes and solutions

Question: The laptop gets hot even after replacing the thermal paste

Good day gentlemen, I have a laptop from about 3 years ago.
As it was before: the cooler worked quietly, the laptop did not get warm when playing games. (I cleaned the dust from time to time and changed the thermal paste and everything was fine).
What happened: The laptop started to get warm when playing games, opened it, cleaned it, changed the paste. nothing changed. By the way, the cooler works normally and outputs heat so you can cook scrambled eggs. This didn't happen before. I was told that most likely this is due to old age and that I either need to clean the processor legs, or bend something else with a screwdriver and clean it, or unsolder something else. I would like to ask you what should be done in such a situation so that the laptop does not heat up.

Question: After replacing the thermal paste on the CPU, the video camera stopped producing an image

Hello people. I have a problem, after replacing the thermal paste on the CPU, the video camera stopped producing an image. In general, it all started like this. I decided to replace the thermal paste. I disassembled, replaced, reassembled, turned on - the monitor was blank, as if it was in standby mode. At first I thought there was something wrong with my memory. I removed the 2nd line, changed places, nothing. Then I connected the monitor to the video output on the motherboard itself and the image appeared. When switching to Vidya - empty. I tried to install the video card in another PCI, same story. People, what do you say? Is Vidyakha covered? But why? After all, I didn’t touch it at all when disassembling the computer. What else can you try?

Message from Predator_ASU

That's it, I solved the problem. And this is how it happened: I decided to go in the opposite direction. At the beginning I changed the thermal paste on the processor. I took off the processor and on the contact area in one place I saw, like, a fingerprint, on the side of the processor, where I was holding it over the edge. I wiped it with a napkin and here’s a miracle, everything worked. Well, who would have thought, because Windows itself was loading, with another video card everything worked. I don’t know, in short, maybe it’s just a coincidence? In any case, thanks everyone

Well, actually the effect was like from bent or missing legs, it happens that the processor starts but does not work correctly with video or memory, depending on what the missing or bent leg was responsible for..
It's great that everything has been resolved!

Question: After replacing the thermal paste, the PC stopped turning on

After replacing the thermal paste, the PC stopped turning on.
When there is no processor in the socket (or there is but not latched), the fans rotate. As soon as I latched the socket together with the processor, the PC shows no signs of life at all. I latched it without a problem - it works. How did it work for me (I don’t know much about this matter yet) building a processor. The master (consulted with him) claims that there is a microcrack in the motherboard.

I connected another power supply and the result was the same.

Old hardware: female - ECS NFORCE3-A (1.0A);
- proc. I don’t remember but the socket is S754.

The system unit was lying idle in the attic (a worker was going there) and I promised to give it to a neighbor’s child (unfortunately his parents couldn’t buy it for him). He is all in anticipation, but I have the same situation.

Who knows - tell me.
Thank you.

Question: Problems with the video card after replacing thermal paste

Good day!

A couple of weeks ago I noticed a problem with the video card: all games run fine, but for example, in BF4 this happens - the game is on great, but about once every 10 minutes the frameseconds suddenly drop by half and stay at this rhythm for a minute or a minute and a half. Then everything returns to normal, but continues to repeat itself. Previously, cleaning the computer from dust (including the video card) without much disassembly of the components, and, just in case, by replacing the thermal paste on the processor, saved me from this trouble. A week ago these procedures did not help. After them, the fps began to remain stable around 60 (previously it was 80-110) and dropped to 20 almost every minute with freezes. I disassembled the video card, blew out the radiators until they were shiny, and replaced the thermal paste (I used KPT-8). I turn on the computer, try it, it seems like a miracle has happened - the FPS has returned to its place and doesn’t even think about falling. But this effect lasted literally for three days. Then everything returned to normal - a constantly low framesecond rate and sagging with slight freezes. Today I disassembled the video card again. On GPU Only about 10-15 percent of the applied thermal paste remains. I was surprised and applied half a millimeter more. Everything remains in the same place: FPS is average and continues to happily drop from time to time to unacceptable values.

AMD FX-8320, Gigabyte R9 280, 16 Gb.

The temperature of the video card at idle is 76-79 degrees, and the same, interestingly, under load. Furmark's full-screen test at 1920*1080 without anti-aliasing produces an average of 23 fps.

Where to dig? Should I use a different thermal paste?

Answer:! It also got warm like that, although there is no miner, and everything is ok with cooling!

Question: The processor heats up after replacing thermal paste

Hello.
The situation is this: Processor Intel Core i3 540 (3.07GHz)
Cooler DeepCool Ice Blade 100 (with 2 fans 700-1000 rpm)
I took out the cooler to replace the thermal paste and clean it from dust, after replacing the paste it began to heat up to 65-70" and idle at 39-50.
Before replacing the paste, the temperatures were 29-37" at idle and 55-61" under load.
Thermal paste DRG-102, I have never had any problems with it since I applied it to the video card and its temperatures were within normal limits.
The plastic feet on the radiator mount are also intact.
Even in AIDA64, the CPU temperature value disappeared, but the CPU temperature values of CPU1,2 remained.
What could be the reason?

Answer: andrei77731, May be. But you check not what kind of thermal paste, but how you applied it, and whether you fully fastened the cooling system. Because this is the only problem that comes to mind. If you have plastic latches, check that they are exactly latched as needed. If it's a frame, check to see if the radiator is stuck on it. And so on.

Question: After replacing thermal paste it turns off

I have Lenovo laptop G550. Today I replaced the thermal paste and cleaned the cooling system. Now the laptop turns off at the slightest load on the video chip. I used KPT-8 thermal paste. Help with advice.

Answer: I put a thermal pad on the chip, the result is the same. SOLVED by simply replacing the paste with arctic MX-2!!!
The temperature dropped by 15-20 degrees. I'm shocked!

Question: Acer Aspire V3-771 - turns off after replacing thermal paste and cleaning

I decided to change the thermal paste and clean it. I did everything using a video clip from the Internet, step by step.
After replacing it, I immediately started using the laptop, but after 3 hours of use it turned off.
then it just wouldn't turn on. I couldn't turn it off in the BIOS. after a while it turned on and worked again for about 2 hours, then it all happened again! After I managed to turn it on again, I installed the AIDA64 program, checked the temperature, everything was fine with the temperature. I checked the hard drive for errors and everything is fine, no errors.
I took the laptop apart again and connected everything correctly.
During disassembly, I didn’t drop anything on the board!
PLEASE TELL ME!

A little background...

Why didn’t I immediately buy “normal” thermal paste...
It all started when I encountered a problem with my laptop (Fujitsu Siemens AH530) overheating. My favorite game Call of duty: Modern warfare 2 started to slow down terribly. It had picked up quite a bit of dust and I bothered to clean it. After several cleanings (about every few months). Someone told me that when cleaning it is almost mandatory to change the thermal paste. I didn’t listen and only cleaned the turbine and blew out the radiator fins, and once again cleaning the devil pulled me to remove the entire cooling system to change the thermal paste. I carefully cleared the “stones” from the old one, went to the store to buy a new one, which was not there... I was simply shocked... I went around several stores computer equipment and she wasn’t in any of them. Since I carried out all these actions after work, I didn’t make it to all the stores before they closed... Remembering everything the world stands on, I headed home.
The next day, in one of the stores, I found Titan Nano Grease (TTG-G30030) at a particularly inflated price ($9.18, instead of the proper $4.04).
There was nowhere to go, and I don’t really understand the prices of thermal paste... I bought it...
After using the laptop for a short time, I noticed that it was working much worse than before changing the thermal paste... I cleaned it thoroughly, blew out the dust, re-smeared the “stones” with new thermal paste... It was all in vain...

Now the point

I won’t say that the heating was critical, but at some moments the laptop simply went into defense. For example, when hibernating or video editing. Temperature tests showed everything was normal. (60-80 degrees Celsius, as in the reviews on the Internet and as it has been since the purchase). The cooler only worked harder, from which we can conclude that at critical moments the “stones” quickly heated up and it simply did not have time to cool.

I was tired of putting up with the inconvenience and decided to look for information about thermal pastes, because... Logically, that was the whole problem. Wandering around the Internet I found an article: “Thermal paste test from a laptop’s point of view”
According to which I read that the best results are given by two of the thermal pastes tested: Arctic Cooling MX-4 and Coollaboratory Liquid Pro. And, since Coollaboratory Liquid Pro is conductive, I decided not to take risks with it, for fear of causing a short circuit in the laptop, and settled on the Arctic Cooling MX-4 (although I had to wait several days for it to arrive, since our computer stores have everything but not what is needed). I practically didn’t overpay for it ($12.11, instead of the due $10.16).

About the thermal pastes themselves.

Titan Nano Grease (TTG-G30030) - 3g tube, actually liquid, snow-white color, thermal conductivity: 4.5 W/(m K)
Arctic Cooling MX-4 4g (ORACO-MX40001-BL) - 4g tube, medium viscosity, gray color, Thermal conductivity 8.5 W/(m K)

Arctic Cooling MX-4 in person:

Sorry for the low-quality photo (the serials have been erased). It was not possible to apply it more evenly, the hands grow from the wrong place... Now you see why I was afraid of the short circuit (the surface of the chips is simply strewn with dangerous places that just ask: “short-circuit me”).

I degreased the surfaces with glass cleaner (or, simply put, alcohol-based Mr. Muscle), wiped it dry, and casually applied new thermal paste. Do not touch the surfaces with your fingers - you will lose several times the cooling efficiency. If you touch it, degrease it again.

Temperature tests, as you understand, do not make sense - it is the same as it was, because it is controlled by electronics. The only difference is in the intensity of the cooler's operation (about doubled), and the temperature jumps have become smoother.
The Titan Nano Grease paste itself is quite good, considering the price, and if not for the small contact area between the processor and the heatsink, it would be enough.

My conclusions

Diagram for clarity:

It should be understood that thermal paste is in no way a coolant itself - it only transfers heat from the stone to the radiator, this property is determined by the W/(m K) characteristic. The higher the number, the faster it transfers heat (unless the manufacturer, of course, cheats with the numbers). If the “number” is insufficient, then the stone will heat up faster than cool, i.e. faster than the thermal paste will transfer heat to the heatsink.

Sorry for the primitiveness, thanks for your attention. I hope this article will really help someone in solving problems with overheating of their favorite laptop.

The breakdown may look something like the following:

The laptop will work for a while and turn off(from half an hour to a whole day without visible problems).
If you conduct an independent express diagnostic (stress test with temperature monitoring), it becomes obvious that the laptop is overheating and preventative cleaning and replacement of thermal paste is necessary, but the cleaning was carried out quite recently (even if, most often, not by professionals). Let's try to figure out why this might happen.

Laptop cooling system design (described in more detail):
copper heat pipe ending with a heat sink that is in contact with the surface central processor On the one side;
on the other hand, it is integrated into the radiator (with metal fins);
A cooler for active airflow completes the design. Additional heat sinks can be used for the video card or chipset, which are in contact with their surface through thermal pads.

Here are some of the most common reasons why a laptop turns off even after cleaning from dust and replacing thermal paste:

For achievement guaranteed result— reduce the temperature of the processor (chipset, video card) if it overheats, contact reliable companies. Only professional service can guarantee the effectiveness of such a procedure as

Have a nice day everyone! In this article we will continue to discuss the question of what to do if the laptop still heats up after cleaning and replacing the thermal paste. It would seem that everything has already been sorted into pieces, but no.

Unfortunately, we must state the fact that even complete disassembly of the laptop sometimes does not lead to desired result. And there are objective reasons for this, which sometimes lie right on the surface.

The most offensive problem may be a simple loose screwing of the bolts on the contact plates. As a result, heat dissipation from the surface of the processor or video chip can significantly deteriorate.

In such a situation, even new thermal paste will be completely ineffective. But let’s still leave this moment for later, and immediately try to look for more banal ways to solve the problem:

So, the first thing you need to pay attention to is the surface on which our heating laptop is installed. Perhaps it is located on some kind of blanket or shag carpet.

Naturally, such conditions will impede the normal flow of cold air that enters the housing through the holes in the lower part. Also, this state of affairs can negatively affect the exit of warm air through the side honeycombs.

The second point that is worth paying close attention to is under what conditions our device begins to overheat: in normal mode or.

And if the temperature rises only when running any heavy applications (games, graphics packages), then this can again be attributed to malfunctions of the already cleaned and serviced cooling system:

This is due to the specific location of the ventilation holes on the laptop body, which are usually found on the left side. And a single propeller on such a stand will most likely be located in the center.

But if the laptop case gets very hot even when simply browsing pages on the Internet or, then you should look at all the running operating system Windows processes. This is done by pressing the keys simultaneously Ctrl+Alt+Del:

Next, in the "Task Manager" you should pay attention to applications that consume a large amount of processor resources. Perhaps it is even one that does its dark deeds and consumes the power of the laptop.

If you still find applications that really put a lot of load on the processor, you can try to remove such a task by clicking on the desired item right click mice:

If the situation has not changed in better side and all the points indicated in this article have been completed in full, it is still worth contacting specialized specialists who, for money, will be able to figure out why the laptop is heating up after cleaning and replacing thermal paste.

And at this point our story comes to an end, if you have any questions, ask them in the comments. Now you can relax and watch a very interesting video about cool tricks.

I did not plan to write this article; I was prompted to write it by many questions about laptop overheating, cleaning it and replacing thermal paste. On the Internet, I did not find a direct answer to the question of how to get rid of overheating of your favorite laptop. In reality, there are many answers to this question, but they are indirect and finding them is very problematic...
If you have extensive experience in using thermal pastes, refrain from reading the article, because... I won’t tell you anything new in it. Anyone who is still interested, you are welcome under the cat.
