According to Noctua comparability it will fit Maxumus VII Impact.

Trident X are 54mm tall w/ fins, 39.56mm w/o fins
Trident X without fins should leave just enough room for fan over them to fit .. 0.44mm clearance.
Motherboard to top of CPU = 8mm
RAM socket raises RAM 3mm
Top of CPU to bottom of RAM = 5mm
Maximum RAM height = CPU clearance +5mm - fan size.
Maximum fan clearance = CPU clearance + 5mm - RAM height
But I am wondering why NH-D15 cooler? There are other that cool just as well and just as quiet for less money.
