Введение

The fan assembly and heatsink’s job is to keep the CPU cool and prevent it from overheating. If your laptop is starting to run hot, your fan may be failing and might need to be replaced.

A common sign that this is happening is the fan is loud and constantly running. It could be that it just needs a good cleaning and you can access the heatsink and fan assembly to clean the fan as well.

If you need to access the fan or heatsink of your Lenovo ThinkPad T480, follow this step by step guide. Be sure to disable the internal battery, turn off the computer prior to starting the repair, and unplug the laptop from the power adapter.

Another note, when replacing your fan assembly/heat sink, it is important to reapply thermal paste first. This will keep your CPU cool by dissipating heat more efficiently.
