@Jens_Rasmussen well, the thing is that it is indoors instead of outdoors for one, so no wind. gotta' use fans. the first floor is okay, but my room is on the third floor and heat rises. it's a little uncomfortable even when the rest of the house is at 70 and i'm gaming. we usually have the house set to 68/69 so a whole 10 degrees on top of that is not fun to say the least.
@Jens_Rasmussen our electric bill is like $150/month in the summer. cut three ways. worth it.
