Natethegreat is correct, there is only the 4 pin power connector so hooking them up to the mobo is impossible (unless there is an adapter cable, if they exist). However, if you have an antec power supply do NOT hook the top and rear ones up to the "Fan only" power connector - if you do this the fans will only turn on when the power supply is hot, which in the p180 would be useless due to thermal isolation. The bottom fan is fine to hook up to the fan only power though. Then again, this is all kinda unecessary because the tricool fans let you pick high, medium, and low to begin with. I cannot say for sure as i've never powered up the fans, but high should be good enough to cool your vid card, and if it isn't buy another fan and put it on the upper hard drive cage.
