The fan on the side that will be covering your ram can be slid up and down to make room for taller ram. For the ram you have selected, you might have to move the fan up 10mm in order to clear the ram. This also means that the total height of the fan will increase. I can't confirm whether or not the ram on your board will be under the fan, but I"m going to assume that it will.
According to your case's homepage, what is the max cpu cooler height that fits?
It would need to be able to fit 175mm in total (making room for the fact you'll be moving the fan up 10mm).
The NH-D15 allows for ram to be a maximum of 32mm without moving the fan. The ram you have selected is 42mm.
