turbo:
if you have no other place then you have no other place. guess what? If i'm in mexico and need to dry weed, it's gonna be hot. after it's dry put it into a mason jar or a coffee can with a lid and store it in your basement (or someplace cool). your situation isn't optimal but nothing's perfect. just be careful in the attic and don't get busted. if the smell is too much for the garage, how will it be different in the attic?
