So I connected two fans to my cpu cooler (pure rock 2) via a splitter to the cpu header on my motherboard. My question is that 1 fan connected to the splitter is 4 pin, and the other a 3 pin (the 3 pin is spinning just fine just not sure what speed it is due to it being a 3 pin). My question is that since the motherboard is obviously sending the signal to the fans via the splitter at what speed to run at, the 4 pin fan will be following the instructions sent but will the 3 pin be following those same instructions via voltage recieved or will it just be 100% at all times?
