So, I've seen a lot of PSUs with shrouds, or cases with "false floors". While I get the appeal of covering up the cables at the bottom of the case, I'm a little confused about one thing... Some (most) PSUs come with a fan on the top. Certainly mine, a CX450M does. So does covering that fan up with a shroud reduce the efficiency, or make it more susceptible to overheating?
