[Figure 1, callout 35]
The VEK280 cooling fan connector is shown in the following figure. The VEK280 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 the Versal device's U1 is cool and rotates faster as the device heats up (acoustically noisy).
The VEK280 board provides a fan controller bypass header J347 and J348 to permit control by the Versal device. See the Default Jumper and Switch Settings for more details.
