Title
iMac Intel 21.5" Retina 4K Display (2017) Heat Sink Replacement
Introduction
Follow the steps in this guide to remove or replace the heat sink in a 21.5" Retina 4K 2017 iMac.
Some images in this guide use a 2015 iMac, which has minor visual differences. These differences do not affect the repair procedure.
This guide is marked "potentially dangerous" because it requires you to handle a power supply that contains large capacitors. Unplug the iMac and hold the power button down for at least 10 seconds to help discharge the capacitors. Handle the board by the edges and do not touch surface components.
