Cooling Fan
The XCVU9P FPGA U1 cooling fan connector is shown in
.
The VCU118 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 initial power on, it is normal for the fan controller to energize at full speed for a few
seconds.
