50°C heat partition
Using the computer in 50°C mode requires installation of a partition that creates two thermal
chambers that keeps preheated processor heat from entering the hard drive and power supply
chamber. The partition also keeps cool air in the hard drive/power supply chamber by preventing it
from mixing into the processor chamber.
Install this partition in the middle of the computer from front to the rear.
