fan placement for phal orchids

[Mercurianmad]

Hi there my two phalaenopsis orchids usually sit in the windowsill that is facing towards the south east. They get the best light here in the house and it’s keeps them safe from my toddlers . This corner doesn’t have a lot of airflow. I have a small fan that I want to place near them to give them some airflow. I know that phals don’t like direct drafts so I’m having trouble figuring out where to put this fan. Do I simply put it far away from the orchids to the point where I can feel a small breeze but there’s no real draft.? If anybody could help me find A way to get these phals a little more airflow without taking them away from their nice windowsill I would appreciate it
