I need to draw 12V from my motherboard but I have no idea where I can get 12V from except fans which is not an option because in my case, if the fans are not connected or not running, my PC will not turn on, even if the heatsink is not touching the processor properly it will not turn on, my motherboard is Dell 0K075K, thanks.
 




The problem is, I have a 24-pin power supply, if I had molex that would be the first thing I would do, I looked into drawing power from CD-drive output since I got one and I have two outputs but they only give out 5V, I was thinking about digging into the cable that supply power to motherboard since it gives out 12V but I'm afraid that it may decrease the voltage and under-power the motherboard.
 


I'm planning to run 8-chan fan controller and water cooling pump, thats why I'm a bit worried about taking power from parts that need it.
