Step 9
• Once you remove the residue, apply a small amount of thermal paste in one area on the CPU.
• The amount of thermal paste applied should be the size of a circle with a diameter of 2mm.
• Applying too much thermal paste may result in the system not ventilating properly, leading to overheating issues.
• Place metal plate back on. This will naturally spread the thermal paste across the CPU.
• The thermal paste is now replaced.
