Lenovo Yoga 730-13IKB Heat Sink Replacement

Введение

This guide describes the process for replacing the heat sink assembly on a Lenovo Yoga 730-13IKB laptop (model number starting with “81CT”).

The heat sink keeps your computer’s Central Processing Unit (CPU) and other components from overheating.

A laptop may overheat (and potentially freeze or shutdown) and make extremely loud or abnormal noises due to a broken heat sink assembly. Cooling fans that are broken or have debris in them can cause strange noises. Debris in the heat sink and/or nonfunctioning cooling fans usually result in overheating. Unplugged connectors, debris, or broken electronics can prevent cooling fans from functioning.

Make sure to clean the heat sink assembly thoroughly before installation. Using compressed air is a great, ESD-safe, way to dislodge debris. No special skills are required, but be careful when operating the ZIF fan connectors.
