I'm new at building a computer. (this is my first attempt) I have an ASUS F1A75 M LE motherboard. I have a Thermaltake TR2-430 power supply. A warning came up that the power fan has 0 RPM. I didn't see a "plug" for the power fans on the power supply. There is a "pin" plug on the motherboard next to the processor fan. What do I need to do ? Should I plug the chassis fan into the power fan plug on the motherboard? Will that mess up the board? I am also not so familiar with this kind of messaging. How and when will I get the answer?
