Quick Fan Re-arrangment question

[cheapshots]

hello guys,

i have a red led 140mm fan on the front of my case, and a black 140mm on the top. i want to make them swap places.
can you do that as i think i read somewhere you have to be careful or a special screw when they are mounted on the top?

As far as i know the screws used to mount a 140 on top are no different than those used to mount a fan anywhere else. I have a top mounted fan on my case, and it uses standard screws.
