What Is the Purpose of a Chassis Air Guide (CAG)

Question

Examlex · Accepted Answer

The Answer is Intel and AMD both recommend a chassis air guide (CAG) as part of the case design. This air guide is a round air duct that helps to pull and direct fresh air from outside the case to the cooler and processor. The guide should reach inside the case very close to the cooler, but not touch it. Intel recommends the clearance be no greater than 20 mm and no less than 12 mm. If the guide obstructs the cooler, you can remove the guide, but optimum airflow will not be achieved.
