Dell Inspiron 15 5584 CPU Thermal Paste Replacement

Introduction

Use this guide to replace the thermal paste on your Dell Inspiron 15 5584's CPU.

The processor, also known as the CPU, provides instructions and processing power for your device to function. It allows your computer to run applications and programs, as well as create the interface you interact with. Thermal paste, the silver-grey substance found above the CPU, allows for the cooling of the processor by dissipating heat. Without thermal paste, or with old thermal paste, the device will eventually overheat, and become nonfunctional.

Before using this guide, make sure to wear gloves and use the proper cleaning tools. It is important to note that, while thermal paste is skin safe, it is extremely toxic if consumed, rubbed into the eyes, or any open orifice. If consumed, contact your closest poison control center.
