Please try not to set you or your house on fire.

Make sure that you dont let either the 12 volt or the -12 volt to touch a ground bus you may have. Ive ran my fans, 6 inches and I run 6 of them in parallel, for days at a time with no issue.
Just remember when dealing with voltage, especially in DC, Voltage is a difference in potential so if you put 12 and 5 together you get 7 but if you put 12 and -12 together you get 24.

That's true. I forgot PSU's have -12v. I was thinking -12v was removed in modern PSU's, but I think it's actually the -5v. I'm not in the mood to Google-fu and find it.

I think you are right about the -5 bus, I remember it use to be there now that you mention it, but it isnt any longer I dont think.
