Cooling Fan
The XCVU37P FPGA U1 cooling fan connector is shown in the following gure. The VCU128 fan
circuit uses a Maxim MAX6643 fan controller that autonomously monitors the FPGA die
temperature pins DXP and DXN. The fan circuit is set up to increase fan speed as the FPGA
temperature increases.
Note: At inial power on, it is normal for the fan controller to energize at full speed for a few seconds
