Sakkura :
I would prefer the NH-D14, since it's cheaper and a bit quieter. Some people prefer the looks of liquid coolers like the H115i though, and it's still a very good cooler.
I'm sorry, just one more question:
for the noctua cooler, does the temperature inside the PC matter? Since the cpu is 150 some degrees (fereinheight)
will it still keep the processor cool? Im not exactly sure what temperature the whole pc is inside, i just know that the graphics card gets about 60 degrees celsius.
I have 1 input and 1 output fan, but i may be getting a Y splitter to have two input or output fans.
