Working on my first build, so have mercy. My chassis fans are acting a little erratic. First problem is theyre reading anywhere between 3000-725000 RPM, second they're jumpy at that.

Third problem is that they won't start on their own. I have to go into the case, and turn them manually to get them to start.

Next problem is interesting. One or more of the fans disappears while I'm in BIOS, and the reappears an instant later. -- I'm wondering if this is due to me plugging in the third fan, because while I had only 2 fans going, it wasn't this unstable.
-Another note, I have these fans plugged directly into the mobo, so I wonder if that affects anything?

Last, is 52C a good operating temp for an fx8350?

Thanks.
