Insert the fan with the arrow facing the sheet metal over the 4 screws.

Place a washer over each of the 4 screws and secure with the M3 nylon lock nuts.

Pic 3 shows the o-ring, then fan, then washer, then nylon lock nut.

Do not over-tighten the lock nut on the fan to over squish the o-ring. You want there to be a gap between the fan and the sheet metal as shown in Pic 3.
