I'm no expert but I'd be more worried about wild temp swings while growing than curing, where moisture will be your prob. Since youre cutting and hanging, just add to curing jar when needed and then keep an eye on humidity in the jar and out and you should be fine as long as humidity is lower outside the jar.
I dont use a fan when curing, but you certainly can. Seems like people who use one just dont have it blow directly on hanging stuff because it might dry out too fast.
You'll be fine.
