NOTE: Global Standard Products (GSP) are a subset of Dell’s relationship products that are managed for availability and synchronized transitions on a worldwide basis. They ensure the same platform is available for purchase globally. This allows customers to
reduce the number of configurations managed on a worldwide basis, thereby reducing their costs. They also enable companies
to implement global IT standards by locking in specific product configurations worldwide. The following GSP processors identified below will be made available to Dell customers.
NOTE: Processor numbers are not a measure of performance. Processor availability subject to change and may vary by region/
country.

ENCLOSURE VENTILATION
If your enclosure has doors, they need to be of a type that allows at least 30% airflow through the
enclosure (front and back).
ENCLOSURE MINIMUM CLEARANCE
Leave a 10.2 cm (4 in.) minimum clearance on all vented sides of the computer to permit the airflow
required for proper ventilation.
RECOMMENDED ENCLOSURE
Do not install your computer in an enclosure that does not allow airflow. This restricts the airflow
and impacts your computer’s performance, possibly causing it to overheat.
OPEN DESK MINIMUM CLEARANCE
If your computer is installed in a corner, on a desk, or under a desk, leave at least 5.1 cm (2 in.) clearance
from the back of the computer to the wall to permit the airflow required for proper ventilation.

All tests are conducted according to ISO 7779 and declared according to ISO 9296 except 90% CPU. For this mode, the system CPU was
stressed at 90% utilization with no other peripheral device actively seeking. This test mode is not specified in ISO 7779, but was measured using
the same microphone distances and measurement techniques defined for the other reported operating modes.
