You are correct. The fans are plastic w/ plastic blades.
I melted a couple blades on mine when trying to get my smoker too hot. I (stupidly) used a 2nd electric fan to blow on the coals. It worked, but moved too much air for my chimney exhaust. The super hot air ended up escaping through the guru adapter port and melted a couple of my fan blades. Easy fix, but now my fan is missing a couple fan blades (still works just fine). I'll be sure to remove my guru fan if I ever pull a stunt like that again.
