    how many fan power plugs are usually on a mainboard? 1 for the cpu, 1 for the case fan?

    i'm reading the manual for the mobo and it seems like that is the case, but my computer case has (2) fans opening, a 120mm and a 80mm, and since there is only one plug on the mobo for the case fan....would it be possible for me to run 2 fans? or am i stuck with 1?

    when you buy fans, you have to pick between 2 different plugs, a 3 pin that hooks into the board, or a 4 pin molex connector, which is the same one that the your hdd and cd drives use. Most current boards have 3 of the 3 pin ones on them.

    Some motherboards have two, some have three, some have as many as six. There are probably motherboards with even more fan connectors, but I've never seen one.

    At any rate, most aftermarket computer fans come with 3-pin to 4-pin adaptors that let them plug directly into the power supply, so yes, you can run as many fans as you want.
