Replacement of thermal paste in laptop

We can say with full confidence that any owner of the laptop at least once asked the question: "Why is the laptop so noisy?". Indeed, now even a child knows that there are electronic boards inside the computer and laptop. But the work of electronics is absolutely noiseless!

In fact, everything is simple - no electronic components make noise, but active cooling systems that remove heat from the heating elements of the laptop. During operation, the metal fins of the radiators and the fan blades are covered with a layer of dust, which significantly worsens the temperature regime. Logic circuits increase the speed of rotation of the fan blades (hence the increased noise level), but even this does not provide an effective heat dissipation - the laptop requires an immediate revision. It would seem that it's enough to clean the cooling system and the laptop will work like a new one. Unfortunately, as in everything, there are some features, without the knowledge of which self-cleaning can not bring the desired results. One of them is the replacement of thermal paste in the laptop.

The thermal paste is a special plastic mixture, a thin layer of which is applied as an intermediate thermal interface between the heating element and the metal radiator. Its distinctive feature is high thermal conductivity, that is, in fact, its presence does not impair the transfer of heat from the chips to the radiators. Due to the use of thermal paste, it is possible to level out the effect of possible errors in the processing of contacting surfaces: when applied, it fills all irregularities, thereby ensuring perfect contact and heat transfer. Replacing the thermal paste on the laptop is to update the factory thermal paste to a new one. The internal device of a personal computer and a laptop is similar, so the thermal paste for the laptop and the thermal paste for the computer are one and the same. Manufacturers offer a wide choice of thermal greases, the composition of which is usually kept secret. Here are just some of them: the customary paste of the Soviet times, KPT-8, based on the organic compound of silicon; Silver from Gigabyte with silver particles; Arctic Silver with ceramic inclusions, which retains its characteristics even at sub-zero temperatures (favorite overcasters thermal paste), etc.

Replacement of thermal paste in the laptop is necessary in the event that as a result of cleaning the cooling system from dust, the temperature mode of operation has not improved. It is impossible to specify exactly which temperature is normal, because it depends on a number of factors: the design features of the laptop, its internal components, the type of programs, the operating conditions. The need to update the thermal paste can be determined by an indirect feature: the laptop is very noisy and warms up even in "light" programs, for example, browsing the Internet or reading texts. In this case, the replacement of thermal paste in the laptop can help.

Any service center will gladly take up this work, because its cost is quite high. If there is constraint in the means or the desire to repair your electronic assistant yourself, you should first make sure that the warranty period of the laptop is over. The fact is that the independent opening of the case deprives the guarantee. So, the replacement of thermal paste in the laptop begins with the removal of the bottom cover of the case, which provides access to the cooling system. We carefully inspect the internal device: many modern laptops use heat pipes, so you should dismantle them without haste. Usually no difficulties arise, the main thing is to remember the original location. After removing the lock (if any) and unscrewing the screws, remove the heat pipe. It may take a little effort, because due to constant heating, the factory thermal paste dries up and glues the chips with the radiators. We remove the old thermal paste, and in its place we apply a thin layer of a new one. Then we collect everything in the reverse order.
