The 12v fans run at 5v will spin alot slower then if fully powered at 12v.

I don't own a pi but would assume you can use a 12v power supply as long as it has the amperage to support it. I may be wrong though.

I use pc fans/led lights/etc I have spliced directly to 12v random power supplies with 0 issues for various projects. You just need to do some reading I guess.

I have a large duffle bag full of power supplies and cordage collected over time. You can pick up power supplies from a thrift store for a 1$

I have the same, although mine is a box full of them. :D

But wont using a 12v power supply spark the board??

And question 2??
