Question Corsair 110r stock fan

[pieguy6mc]

So back at black Friday I got a deal on a Corsair 110r gaming case that came with a free red led Corsair quiet edition fan. Should I replace the stock fan on the back with the one I got for free or should I stick it somewhere like the front so I have more fans?

Or like put the LED fan in the back and out the stock in the front. I think the one I got is 120mm.

Rear would be the logical position for me. I'd move the no LED fan to the front since you can't see it when looking at the case head on. The LED fan at the back would spill some light to the innards and the side of the case(atop the desk space).
