No, but I’d make sure the clamp has wire ties just in case.

I think they only draw 5 watts

Looks like it will do the trick. Like @dbrn32 said, make sure you zip tie them to the pole so they don’t pop off under negative pressure

does it rotate? i have been looking into a rotating fan for up top
vivosun has a couple oscillating clip on fans on amazon
What I did to eliminate that was cut a piece of 3/8" rubber automotive hose about 6" long and slit it down one side. Slide it over the tent pole and attach your fan to it. The rubber helps it from slipping and also makes the clamping area a little bigger for the fan to grip.
