There are many ways to reduce the heat of a laptop. However, most of the well-known methods have a lot of risks, such as the existence of major disadvantages, the need for expertise, or the introduction of money. So today, I will talk about categories of risks, knowledge, or ways of getting money, and ways of not having risk, knowledge, or money, but which are also effective, but that do not contain money.
How risk, knowledge, or money comes in
Reapply Thermal Grease (Thermal Grease)
The most representative of the risky methods is to reapply thermal grease, which is a fundamental solution to the hardware. To understand the reason for applying this, it is necessary to know the principle of heat dissipation of PC and notebook roughly.
Usually, a metal plate with a high thermal conductivity such as a CPU or graphic card is used for heat-generating parts, and a thermal grease is used for the heat sink (thermal grease is in a toothpick-like liquid state for those who do not know). Then, the metal plate and the heat sink that efficiently conduct heat are cooled by a cooling fan (cooling fan), or the heat is cooled through cooling water (water-cooled type) by heat circulation In order to transfer the heat between the metal plate and the heat sink in the heat source (CPU, graphic card, etc.), thermal grease is applied to eliminate the air layer and direct heat more easily. This is because an air layer is created by attaching metal together without it, and thermal grease is an object having a heat conduction efficiency 50 to 500 times higher than air.
However, as you can see, this means that once you buy a thermal grease, people who do not have a full computer will not be able to distinguish between the CPU and the graphics card, and they will disassemble the computer and apply thermal grease directly to the part It is extremely dangerous to do so. Not to mention a notebook that is smaller, more detailed, more complex and more sensitive than a PC. And most importantly, the CPU is very thin and there are a lot of metal pins, but the beginners ignore them (in fact, they have experienced it), and in the process of reapplying thermal grease, these pins are very likely to fail, There is also. This method is not really very professional, but it requires a bit of computer knowledge, and if not, it is a very cumbersome way to go to the repair shop. But it's also the most effective way to do it right.
If you are interested in computers, I think it is the opposite of overclock that you have heard quite often. By reducing the amount of power generated by the PC with the software setting, you can eliminate the cause of the fundamental rise in temperature while keeping the performance degradation to a minimum. . If the above-mentioned thermal grease is a way to get rid of elevated heat, this method will not heat up in the first place.
However, this method is not so difficult, but it is necessary to have basic computer knowledge. You have to know the amount of power that does not degrade once, and you have to adjust the amount of power continuously to find a suitable point where the PC will not go down. It is also one of the major drawbacks that beginners can not cope with problems caused by under-bolting that may occur in the future. Also, there are a lot of undervolving software that does not work in older operating systems (such as Windows XP).
But if you can do it right, it's one of the best ways to solve heat without having to pay.
Cleaning the inside of the notebook, dust outside
It is also very intuitive and has a direct or indirect effect on the hardware. It is the way to open the notebook case and remove the accumulated dust.
The longer it is used, the more effective it is, and the more likely it is to have a positive impact on the life of the notebook, but the reason for belonging to the first category is that it also has to be disassembled.
It is a simple risk that a person who does not have any knowledge of the computer is decomposed and reassembled. In the process, parts can be damaged or improperly assembled, which not only increases the heat but also can seriously damage the notebook itself. But doing it right is a great way to extend the life of your notebook and increase the cooling effect.
Laptop Cooler, Cooling Pad, Cooling Stand, Cradle, etc.
It's the most controversial and talkative way to do it indirectly without taking direct action on your laptop. Cooler, cooling pad, cooling stand, cradle are all the same thing. The cooling principle is to support the pedestal which is made of plastic material under the notebook, and the cool fan is built in the pedestal so that the inflow amount and circulation speed And cooling it.
From the conclusion, the effect is certain. But the effect does not come from the cooling fan, but the notebook is slightly raised from the floor to mount the pad. In fact, due to the slight lifting of the notebook from the floor, the ventilation holes of the notebook are not clogged, , Which results in a cooling effect.
At first glance, rotating fans, which seem to help catch heat, are virtually useless, and certain fans and certain notebooks have a bad effect on each other, which can cause even more heat. That is, the pad works, but it's just because you lifted the laptop slightly from the floor and buying a cooling pad is a waste. I think this is valid until something new, new-style pads do not emerge, and so does GKKmon's idea of using it directly from an expensive cooling pad to a low-cost mount. In fact, there is also a Yu-Tuber experimenting with this, which surprisingly results in a slightly better cooling effect on the numerical value of the various versions of the cooling pad.
Easy, simple, and do not require money or knowledge
Raise the top of the bottom of the notebook slightly by supporting an eraser or anything
This is a predictable method. It's really simple and primitive, but it's a great way to do it, putting an eraser-like object on the back of the laptop so that it does not touch the floor directly.
Naturally, you can use any object, not an eraser, and there is no money, no knowledge, no risk, but the effect is excellent. Most laptops take in air from the bottom surface, and the air is exhausted to the side and rear with the heat passing through the inside of the body. However, when the notebook starts to heat up, the bottom portion of the notebook itself gets hot, which causes the hot wind to enter the room and the cooling efficiency drops considerably. Also, if it sticks to the floor, it will be difficult to get air into the notebook.
It is very easy to see the notebook with a noticeably lowered temperature when you put in only one eraser because the air is also circulated very smoothly by disappearing the phenomenon that the heat is raised by direct contact with the floor by floating it with the eraser lightly. This is a great way to show the overwhelming performance and fade ratio compared to a cooling pad that has to be cumbersome and must be purchased separately, the noise increases, and the volume is so large that it loses the advantage of the notebook.
Limit maximum processor state in Power Options
This method is a software control method like the undervolving mentioned above. Unlike undervolving, it is a very simple method without any related knowledge at all. It's easy to change the setting so that it does not make 100% of the performance of the PC, but 99% ~ 80% of the performance. The effect is excellent, but there is some performance deterioration as you can see from the principle. However, the performance degradation is not so large compared to the cooling effect, assuming that no operations such as gaming are performed.
If you have finished all settings, click 'Apply' or 'OK' to save and reboot your computer. When you apply it, you do not get too much of a computer at the time of rendering or gaming that the processor is 100% running, but the speed of the process is slowing down and the heat does not rise above a certain temperature.
Using all the methods mentioned will surely catch the fever, but I personally think that the two methods without risk will be effective. I hope all of you will be able to get rid of your laptop fever stress.
