ok so my new case fractal r5 has 2 fans in the case, and my old case rosewill challenger has 2 fans as well,
the rosewill challenger has 2 fans with 9 fan blades each, one of them is working fine and the other one, one of the fan blades fell off so now there is only 8 fanblades on the one fan.. will that make a big difference or am I fine to put them in my new case?
also, right now my fractal has intake in the front, exhaust in the back, if I add these 2 new fans should I add another front intake, and a top exhaust?

also noise isn't a big issue for me, I just want to know if 1 fan blade is missing out of 9 blades, will it make a drastic difference.. thanks.

so can I use the fan that's working, and If so, should I have it in the front for intake, or the top for exhaust?
