Nepenthes leaf curling? I don't think it's water...or is it?

the water on my plants dries within 30 minutes to an hour. There's a fan that turns on every other 1/2 hour for 1/2 hour.

How close is the plant to the fan and how strong does it blow? Sure, nepenthes don't mind breezes by any means, but too strong a wind for just about any plant can stunt their growth. It's one of the reasons why the higher up a mountain one goes, the less tall the vegetation steadily becomes, the wind is stronger higher up. I don't think it would cause the curling, but who knows?

It's about five feet away but it's barely strong enough to move paper but strong enough for mold to not set
