Hi guys, I am replacing the stock fan/heatsink on my HIS Radeon HD 6790 with the Arctic Accellero R2 Plus. This fan has a 3 pin and 4 pin option for the fan. The stock fan is only 2 pin...black and red. The aftermarket fan's wiring is black, red and yellow, and black (ground), red (VDC), yellow (signal) and blue (PWM). My question is can I just splice the original connector with just red and black into the aftermarket wiring? The fan came with a molex adapter but I'd rather the video card be able to regulate the fan rather than it just be going full out all the time. Is the factory red and black also considered VDC and ground? Thanks in advance! More about : 6790 fan pinout aftermarket fan replacement "There is only one way to boot a computer..."
