I have a case fan that has a 3 pin female cable. Where do I find an adapter cable to plug it directly into the daisy chain power supply? Most of the adapters I've seen they seem to have 2 pins (male end) to 4 pin molex, I tried that and it does not power my fan. I have a large fan, not the small ones. I guess I need something with 3 pins (male) not 2. Any suggestions?
