Is my fan to much?

Can my babies have too much wind on them? They are "vibrating" quite a bit with b the fan blowing but they aren't bending or anything. I just didn't know if it might stress them out to much or anything. If it helps give me an answer they are autoflowers about 2 weeks old from germination and about 2 inches tall. Thanks in advance for any advice
 
Thanks man. I think mine are ok then. They are 'twitching' alot but they aren't bending or anything. They actually look like they are moving about like the leaves on the plant in the video
