Introdução

Follow this guide to replace or remove the heat sink in your Lenovo YOGA 730-15IKB. The heat sink transfers heat away from the central processing unit (CPU) and graphics processing unit (GPU). The fans blow cool air over the heat sink to keep it and the other components from overheating.

Sometimes, removing the heat sink and replacing the thermal paste on the CPU with high quality paste can make your computer run faster or cooler. You will also need to remove the heat sink if you are replacing your motherboard.
