Battling overheating new 360 build

as far as the fan, though I've never personally witnessed one come apart, I've heard enough stories about holed batteries, and even holed hoods from shucked blades. I know that when I'm under the hood, and I'm revving up an engine, I watch where I stand so I'm not in the line of fire should one of those fans come apart! A friend of mine was blinded in one eye, by a disintegrating fan on a mini bike. Better to be safe than sorry.
