those are fan headers, you plug fans directly to them. the mobo gives it power, meaning you dont need to plug the fan to the psu. However, there are options, like you can use the psu to power your fans also, this is obvious if you look at the connectors.
Ok, thanks! Just to sum this up; You put the Molex cable, the 4-pin side, in the case fans, and then plug the Molex cable in the Female molex power plug, is that correct? This seems a lot simpler than what I had imagined.
yes your got it almost right....use a female molex from power supply cable. then plug in the fan cable adaptor...
there two types of them 4 pin and three pins. lok at the end of your fans top make sure you buy the right one. then plug the fans into the power cable and your done. (just to let you know there no fan speed reg this way the fans run 100 percent all the time.)
