Introduction
Disassembling IBM ThinkPad A30 CPU Fan
Disassembling the CPU Fan can be helpful towards a project in cleaning or replacing the fan. If the fan is overheating and needing to be replaced, then your computer may start shutting down without warning.
The CPU Fan is how the computer cools itself during usage. The fan dissipates the heat that the computer creates while in use. If the fan was to stop working, it would cause the processor to overheat and damage to the computer.
Prerequisite: Battery, uppercase, LCD screen
Before using this guide, you can first try running a 4k video on YouTube and if the fan starts running after you load the video, then the CPU fan is fine.
