Difficulties with cooling a PC can provoke slowdown in operation, errors in saving information and a complete breakdown of the system. To solve this situation, after the warranty period has expired, it is required to disassemble the laptop and lubricate the main components with thermal grease. The tool will help to eliminate the air gap between the heating board and the radiator, which helps to eliminate unnecessary temperature indicators.
The thermal conductivity of the substance is greater than air, which will significantly improve the functioning of the device. From the list you can find out which thermal pastes for a laptop will be the best, which ones are required to be used for the processor, video card, RAM and motherboard. To select the best thermal paste for a laptop in 2020, this rating was compiled.

Main selection criteria
The question often arises, which thermal paste is better for a laptop. To answer it, professional advice will come to the rescue:
- Thermal conductivity. This indicator is the amount of heat that is able to pass through the material. This parameter is characterized by the coefficient of thermal conductivity. The larger it is, the stronger the thermal paste will transfer heat from the processor to the cooler.
- Viscosity. The predominantly viscosity marks the comfort of application. Too liquid thermal paste can spread from the edges and flood the motherboard, and very viscous cannot lay down evenly on the top. The viscosity is measured in Pa · s. There is no recommended indicator. During the purchase, it should be noted that pastes with insufficient viscosity are enough to drip into the center of the processor case and press down with a latch, with a high one you will need to smear it yourself with a thin layer.
- The range of temperature indicators. From constant operation in aggressive conditions, thermal paste loses its own characteristics over time. It dries up, the thermal conductivity decreases. The temperature range will show the largest range at which the thermal grease “works”. The larger the parameter, the longer the substance will keep its initial state.
- The composition of the thermal paste. Factory-made pastes will contain ingredients that are necessary to maintain performance. In some cases, they will contain impurities and metals for improvement purposes. However, there are also fake products on the market, the composition of which is unknown even to the developers. Considering that thermal paste is under regular heating and emits various vapors, there is a risk of harm to health.
Top Models
Correctly selected paste and its proper use can greatly improve the temperature and performance of the CPU. The wrong type of thermal paste and poor application can practically degrade performance. To choose a quality thermal paste, you need to read these recommendations.
Zalman ZM-STG2
The product in question is extremely common from a well-known developer of cooling systems. The manufacturer produces high-quality, but rather expensive, coolers and radiators. This thermal paste also has all these qualities.The cost for an ordinary 3.5 g syringe is approximately 550 rubles.
Operating temperature indicators also do not differ in high characteristics (-40 + 150 degrees). For most consumers, including those with entry-level gaming PCs or laptops, that's enough. In addition, extensive tests show that the paste will perform its own task perfectly.
Before the purchase, the country of origin is checked without fail: characteristics and tests confirm that the difference between the Korean and Chinese versions is 20 degrees. In addition, it should be noted the low "stickiness" of the paste, as a result of which it is difficult to apply it to the top of the processor or video card.
Pros:
- considered a dielectric and completely harmless to metal processor parts;
- made from environmentally friendly material;
- will be RoHS compliant;
- a gray tone is easier to notice during subsequent removal (after 1-2 years, when it will need to be replaced);
- a tube in the form of a syringe, which will facilitate the application process;
- density at a temperature of 23 degrees will be 2.88, which is comfortable for application;
- resistance during heat transfer from the processor to the radiator will be 8KW;
- the paste will perfectly perform its own functions at temperature indicators in the range of -40 +150 degrees;
- in composition it is similar to sour cream (it will not spread over the board, and also resist smearing);
- capacious tube;
- significantly reduces temperature indicators;
- one tube is enough for 5-6 processors.
Minuses:
- narrow sides on the syringe tube for squeezing out;
- overpriced;
- after a year, cleaning and reapplication is required.
Arctic Cooling MX-4
Pasta from a Swiss manufacturer, extremely common on the domestic market. Service centers and private craftsmen very often turn to the use of this substance, since the composition will correspond to the proper level of quality. Its main advantage will be that it has an impeccable consistency - moderately liquid for comfortable spreading and moderately viscous in order to fix it on the treated coating.
With regard to performance, there is a proper ratio of thermal conductivity and temperature peaks. The value of 1 component of this substance will be 8.5 W / mK, which will make it possible to use the paste in productive devices. The loss of the useful characteristics of the composition will begin when the indicator reaches 160 degrees - not the maximum parameter, but if there is a proper cooling system, it does not come to this.
Pros:
- proper thermal conductivity will not hinder processor overclocking;
- there are various packaging options (for 4 and 20 g of paste);
- excellent composition.
Minuses:
- overcharge.
Titan nano grease
The price of this paste will be only 350 rubles, which will make the substance the most popular among consumers. The tube is made in the form of a syringe with rectangular body walls.
The front part is covered with a comfortable wide hood. There is only 1.5 g in a tube, but this amount is enough for 3 processors. Thermal conductivity is considered to be quite high and amount to 4.5 W / mK.
Pros:
- when, before use, the parameters of the temperature indicators of the CPU were 90 degrees, then they will decrease to 50-60 degrees (at maximum loads);
- the syringe presses a small layer, which is required for proper use;
- budgetary cost;
- extremely high thermal conductivity.
Minuses:
- in a tube only 1.5 g;
- has a thicker composition than in other analogues, you can find heterogeneous parts.
DEEPCOOL Z9
The popular developer of computer coolers and fan components also produces a unique paste that perfectly complements the main products. In a situation with this substance, such a comment will look acceptable - the manufacturer actually produces heat-conducting thermal paste to meet the requirements of its own cooling systems.
Due to its special composition, the substance can withstand temperature indicators, including up to 200 degrees, which will determine its use in powerful structures. However, the thermal conductivity index does not in all cases support such a gust - 4 W / mK is sometimes quite small in order to obtain maximum acceleration.
Pros:
- high temperatures (from -60 to +200 degrees);
- affordable cost;
- proper thermal conductivity.
Minuses:
- certain difficulties arise during application due to the composition of the thermal paste.
Coollaboratory Liquid Pro
