Dropped a few nuts into the a/c fan

hahahhaa,
this is funny.
I was trying to built my air box, and yesterday few nuts slide over between my fingers and found their way straight into the a/c fan. It is the bigger fan of two, which is located on the passenger side. I manage to get 2 of them out, however, I am thinking that 1 or possibly 2 of the bolts are still remaining at the bottom of the fan box. Tried to see with a mirror and a torch if there is any nuts left however, cant see anything.
What could go wrong if I just forget about this and lets say 1 or 2 nuts have left there?

if they sieze the fan it could get messy.... that's about it

I have to say I have lost a nut or two in there me self.... Trying to get them out is so hard

I think one of them is still in there, should be fine aslong as they are small, they probably will fall out after some driving.
