What conditions are you riding in? I just got done a couple day sessions in SoCal at Mountain High and the Scott Storm goggles (with NO fan) did me well with no fogging whatsoever. It's true that the nose area is a little roomy, but you can just move the goggles further down on your nose, or use a facemask/neck gaiter/balaclava if you are worried about your nose getting cold (my nose was fine). FYI I wore mine with a helmet and the helmet's goggle strap made sure that my headgear didn't go flying on bad falls.
+1 Scott Storm, especially if price is a factor in choosing your OTG
