The VPK120 cooling fan connector is shown in the following figure. The VPK120 uses the system controller to autonomously control the fan speed by controlling the pulse width modulation (PWM) signal to the fan. The fan rotates slowly (acoustically quiet) when ACAP U1 is cool and rotates faster as the ACAP heats up (acoustically noisy).

The VPK120 board provides a fan controller bypass header J347 and J348 to permit control by the Versal ACAP. See the Default Jumper and Switch Settings for more details.
