Whatup1049, thanks for that info, but I do understand what is being said though.
The reason for me buying a new fan is because people are saying that when you get the 12v out of the fan, it's really loud. So, what I am planning to do is get a new fan that has the same capabilities but quieter.
That idea with the wire to the casing is neat too.
Last thing is which type should I get: 3 or 4 wire one and how do I hook it up?
Thanks
