Hello guys i just want to ask if the noctua NH-D15 is compatible with my Fractal Design ARC MIDI R2. and Gskill Ripjaws X. :33 I already searched the internet and i think it will fit? but im not sure about my ram clearance. will the D15 still fit on my case if i move the first fan higher to give way for my ripjaws? I just wanna make sure before i buy the cooler thanks guys! sorry for my english btw. :3 Allen~
