Fan placement advice

[daveg12]

I have a Corsair r300 case with a 140mm fan at the front and a 120mm on the back, i have a a extra 140 and 120mm fan should i just leave them out of case? If not where the best location for addition fans.

Thanks

if 0possibl put one on the top as an exhaust
you don't REALLY need it, but it might help the air flow within your case, better thanit doing nothing!±
