ok, first off, thats a MID tower-keep in mind, most midtowers get hot! really hot! b/c they dont have enough fan spaces. I have a chiefteck aluminum case-full tower btw, and its got 5 fans-plus cpu and psu fans. so it keeps fairly cool. most midtowers-only allow 2 fans-thats killa! here's something you'll want!
