So i have my stock cooler sitting here doing nothing now that i have my mushashi and im trying to make it into a fan. It has 4 wires, the red and black are defiantly power but does anyone know what the other two are?
I don't wanna put power on them and fry it or something. Its amazing how quiet it is with out the heatsink in there lol.

Okay with the wires, red is +12v, black is ground, yellow is tac, blue is PWM. At least that is how it should be.

Unless you want PWM control or TAC, then yeah just leave them.

TAC is used for temp control.
say the GPU hits 40c and CCC is set to bump up the fan speed then it hits 40 to 50% TAC is what regulates that
