The KD240 Starter Kit is built with an installed passive cooling solution (see Figure 1). The passive heat sink allows you to exercise the full 6.5 W AMD Zynq™ UltraScale+™ MPSoC application power budget without any additional accessories.

Optionally, a 12 V fan (available and sold separately) can be installed on top of the heat sink. If used, be sure that the fan is plugged into the connector designated in Table 1. The fan connector is keyed to ensure proper orientation.

Variable fan speed control can be implemented through an FPGA-based PWM fan controller. The fan gating signal is connected to an FPGA HD I/O bank pin for control. Consult the corresponding KD240 Starter Kit carrier card schematic for specific pin assignment.
