Heat sink
Description
Heat sink (includes thermal material)
NOTE:
To properly ventilate the computer, allow at least a 7.6-cm (3-in) clearance on the right side

by a temperature sensor and is designed to turn on automatically when high temperature conditions
exist. These conditions are affected by high external temperatures, system power consumption, power
management/battery conservation configurations, battery fast charging, and software requirements.
Exhaust air is displaced through the ventilation grill located on the left side of the computer.

Thermal pads and thermal paste are included with all heat sink, system board, and processor
