All chapters of this manual are valid for the KBox C-103-CFL-4, the KBox C-103-CFL-2 and
KBox C-103-CFL-1 with fan tray under consideration of the mechanical differences and the
description in this section. Please refer also to the subsection 12.1.2 “Mechanical

The KBox C-103-CFL with fan tray chassis extension is designed to provide a better airflow through the system
chassis. The KBox C-103-CFL-4/-2/-1 can be only factory equipped with the optional fan tray (Figure 32). The fan tray
slot is external mounted to the bottom side of the KBox C-103-CFL-4/-2/-1 chassis and comprises a fan tray (Figure

The fan is integrated in a user-friendly, replaceable fan tray (hot-swapping). The fan tray is designed to be inserted
into the fan tray slot (Figure 32, pos. 6) on the bottom side of the KBox C-103-CFL-4/-2/-1. The fan tray simplifies the
installation and removal of this component, even during operation.
The fan rotation speed is temperature controlled in dependence on the CPU temperature. Thus, a reliable air
circulation for optimal active cooling of the KBox C-103-CFL-4/-2/-1 is ensured.
The temperature conditions of the system (depending on the environmental temperature and the system load) are
detected by the CPU temperature sensor.
In order to ensure a clean air circulation through the system, the fan tray slot provides an installed
air filter (Figure 32, pos. 3).
The air filter, which protects your system against dust and dirt, is washable and may be replaced during operation;
refer to subsection 10.4 “Cleaning the Air Filter”.
