I am going to get a corsair H100i and I want to get some SP fans....So...Im picking between the SP120 silent ones or the high performance ones. Note these will be on the radiator as a EXHAUST configuration. Maybe you might say silent but I have a fractal design DEFINE R4 with window so it will be silent, just not as silent cause it has a window. So...SP120 SILENT or HIGH PERFORMANCE?
