and when compined to prime 95 blend test 3911Mhz running its core 0 58-63,core 1 66-70, core 2 64-70, core 3 62-69
is that ok values? i have 3 reason moment is not litted would like to change top blue tone whit led and(woudl that increase temperature?) the fan has 3 cables unlike standard fans that goes whith the haf x some times get warning message of fan running lowerspeed 600rpm from bios
