Hello, I have a problem with my middle fan not working.Basically the fan starts spinning when I boot for 1-2 sec and then it stops.Also when I set the speed fan to 80% it starts spinning again but it doesn't when it is below that level. I have been informed that this has to do with the PWN controller and I have observed that the middle fan has an additional green cable which the two other fans haven't got. I have watched a video on youtube about adding a circuit which converts the PWN signal to voltage but I don't know how to make it. Can anyone give me some clue ?
Thank you
