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. Figure 7-65 50°C heat partition To replace the partition: 1. Prepare the computer for disassembly (Preparation for Disassembly on page 41). 2. Remove the access panel (Access Panel on page 42). 3. Remove the cables from the arm on the fan duct, and then remove the fan duct (Fan Duct on page 84). 4. The partition connects to the front and rear of the chassis. First, on the rear of the chassis, push the partition toward the rear of the chassis (1), and then lift it up to disengage it from the chassis (2). 102 Chapter 7 Removal and Replacement Procedures
