How Important Is It to Apply Thermal Paste on CPU?

CPU Thermal Paste

With the improvement of the CPU running speed, the temperature of the CPU is also increasing, so various cooling devices have appeared on the market. No matter what cooling device is used, it's necessary to use thermal grease or other thermal conductive medium to connect the CPU and the cooling device.

The surface of the CPU cover and the surface of the heat sink, we feel that the surface is very smooth, in fact, their surface is not smooth. There is very little difference in surface voids on the material, and when the heatsink is placed on the lid of the CPU, their surfaces are not in 100% contact. To make matters worse, CPU covers and heatsinks are often made of different materials that expand and contract differently when heated and cooled.

Thermal paste is a dense composite material, which is used to improve the thermal contact between electronic components and heat sinks. Defective and damaged, and prolong the service life. Using thermal paste on CPUs is necessary because they are very inefficient components and consume a lot of energy in unused heat. This paste is usually made of zinc oxide and silicone, which has high thermal conductivity.

If the CPU does not have thermal paste, the thermal efficiency of the CPU will not be as efficient as it should be, and the operating temperature of your CPU will be higher than that of the CPU coated with thermal paste. When the temperature exceeds a certain temperature, the CPU may automatically reduce its running speed to prevent overheating or even burning. It is possible to run the CPU without thermal glue for several years and still use the computer, but the CPU will often automatically alarm and reduce the frequency, and the use experience is very poor.

Correctly adding thermal paste is an important part of the computer cooling system. If there is no thermal paste or the thermal paste is dry and cracked, it will affect the operating efficiency of the CPU. It is best to replace it once a year to overhaul the heat dissipation of the CPU and replace it with new thermal paste.
