The thermal paste of the processor serves to drive the heat generated by the processor to the heatsink and by means of the fan that has the heat sink is removed the heat. When the processor goes to work doing operations and mathematical calculations, it is heating up. To make this continue working properly you have to get that heat. Then that’s where the dough ends and the processor heatsink comes in.
When the processor and the heatsink make contact, there are tiny spaces between them. The thermal paste is used to cover those spaces and to make the conduction of heat flow correctly.
Thermal paste is usually a thick liquid material composed of metal oxide, carbon and silicone and in some cases, they carry ceramic components. It is usually grey, white or orange.
What if the processor does not have thermal grease?
If the processor does not have thermal paste, it will not transfer enough heat to the heat sink, which would cause the processor to overheat. When that happens many things can happen, such as turning off the computer suddenly or causing the processor to damage itself. More likely to happen than the second.
Maintenance and change of the thermal paste
As long as the thermal paste is of good quality and applied properly it can last for more than 7 years. However, there is no fixed duration. It is advisable to change it when there are problems of heating the processor or that the computer shuts off suddenly by high temperatures and other possible causes have been ruled out.
The amount to place should be low since too much can also generate overheating.
As in the CPUs (Central Processing Unit), the same measures must be taken into account for the GPU (Graphic Processing Unit) as these are the processors of the graphics cards.
