Can I ask another dumb question for good measure?
My P8P67 motherboard has the following fan ports...
1 x CPU Fan connector (4-pin)
2 x Chassis Fan connectors (4-pin; 3-pin)
1 x Power Fan connector (3-pin)
I bought a stand-alone controller that supports four fans and I'm wondering if I should send it back and just control the fans with software instead. Theoretically I could just run my three case fans from the Chassis/Power fan ports, right? Would there be any harm in plugging a 3-pin fan into a 4-pin port (see image below)? The manual for my P8P67 doesn't address this question, though I'm guessing it should work fine as long as I use the right-most pins (the ones nearest the plastic tab). Right?
My other question relates to the Power Fan connector. If my Google research is correct, that port is meant to monitor the fan speed of the PSU, but I'm unsure of whether it has regulatory control or not. Do any of you have experience with this feature? My PSU doesn't support fan monitoring so I'd rather use that port for controlling another case fan, if possible.
