If I'm using a Noctua NH-D15S (the holy grail of CPU air coolers) and I'm using an ASrock Fatal1ty Gaming K6 motherboard with 16GB (2x8GB) of DDR4 3200MHz G.Skill Trident-Z RGB RAM, will there be any physical obstructions of memory DIMM clearance or the PCIe 1x slot at the very top of the PCIe slot lineup?
