Thermal paste replacement on the motherboard and processor

Passo 1 — Open the computer housing

First step, locate the screws to disassemble the side of the housing.

Passo 2 — Locate and disassemble the fan / heatsink from the CPU

The cooler consists of a heatsink and a fan located above the processor. The heatsink consists of an aluminum or copper part, which transfers heat from the processor and allows it to be evacuated by the fan.

Passo 3 — Cleaning off the old thermal paste

To put back new thermal paste, it is important to clean the remains of the old one

Passo 4 — Installation of the new thermal paste

Once the two surfaces are clean, the new paste is applied on the processor side.

Passo 5 — Reassembling the computer

We start by reassembling the heat sink, by screwing each piece (don’t over-tighten it all at once!)

Passo 6 — Check that the processor is cooled

The temperature of a processor at rest depends on each processor. To know its exact specifications and to know if you are in the standard, you just have to consult its technical sheet on the site of Intel or on that of AMD.
