First, read the English article below.

The bead of paste should be smaller than a BB or a grain of rice. If you’ve read that it should be “pea-sized”, that is far too much paste, and you will end up with paste on your motherboard. There is no need to spread the paste for circular coolers, as the pressure of being applied will spread it evenly across the surface. Install the heat sink with even pressure from all sides, and the bead that you placed on the surface will spread over the entire contact surface. This will create a thin, even layer that will fill any gaps but avoid excess build up. As heat is applied, the paste will become thinner and spread more towards the edges. This is why using a small amount of paste is important, as a little goes a long way. It can be difficult to check if your paste has been applied correctly. If you break the seal that is created when you install the heat sink, you will need to restart the process, first cleaning off the old paste and then reapplying it. The CPU fan wire should be plugged in the CPU fan socket because it mostly has the PWM function which allows the computer to adjust the fan speed automatically without changing voltage. Check that the fan is spinning. Enter the BIOS by pressing F1 or Del key during POST. Check if the temperature is normal, CPU temperature should be below 40 degree Celsius when idle, same for GPU. 

Now, please write a short abstract for it in Vietnamese. Abstract:
