Basically i got a new cpu cooler which was the noctua NHD15. Install went well no real problems. I booted it up and i got an error for the cpu fan saying something along the lines of "no cpu fan detected please check". After some more testing i found that the Y splitter which allows both fans to convert into one socket was the problem. Each fan in the socket alone work perfectly fine but with the splitter i get this error. When i use the splitter i can controll the mode of the fans e.g AUTO,DC,PWM but the actual rpm and such does not show up. Could really use some help.
