Lenovo IdeaPad Flex 5-1570 Heatsink Replacement

Introduction

The heatsink (or heat sink) is a passive heat exchanger that transfers heat in a device. The heatsink disperses heat from another component in the device to prevent the device from overheating.

If you find that your laptop easily overheats or is running at higher temperatures than normal, it may be time to replace the heatsink. Follow these simple instructions to remove and replace the heatsink in your Lenovo IdeaPad Flex 5-1570 laptop. Make sure to turn off your laptop and let it cool for 20 minutes before proceeding with the guide.

Don’t forget to follow our thermal paste application guide after you have removed your heat sink and are ready to reassemble your device.
