dumb mobo fan connection question

This is the first computer I've built, so sorry if this is a stupid question:

I have an ABIT KV8 Pro, and there are about 6 3-pin fan connectors on board, that are all indicated as "Capable of providing power for 6 auxiliary fans". One is dedicated for the CPU fan, which I've already hooked up. The other five are for a chipset fan, a system fan, a three auxiliary fans.

I've installed 2 ventilation fans (on in front, one in the rear) that I have just plugged directly into the standard 4-pin power supply connections.

Are the 3-pin ones on the board for things like extra GPU card fans, or are they meant to control ventilation fans like I have based on temperature or something? Is the way I have it hooked up correct? I imagine the two ventilation fans will run continuously the way I have it. Would modifying the connections and hooking them up to the mobo allow temperature based fan operation?

To further complicate matter, there is a three pin connection from the power supply fan that allows the motherboard to monitor power supply fan speed. It says to connect this to any of the mobo fan connectors (case literature), so that the mobo can monitor. Will it work if I plug this into one of the auxiliary fan connectors, even though they appear to "power" fans, and not monitor?

Any help would be appreciated. Thanks
 
The one from the power supply is so that your mobo can monitor the speed of the fan in the psu. you can hook it to any of the free fan headers on your mobo. No problem, will work fine. The extra fan headers are for any extra fans you put in your computer that will fit those connectors. I would advise against plugging any high speed 92mm or 120mm fans to those headers though. Might put too much draw on your mobo.

so would that make connecting your video card to mobo with a 3-pin adapter out of the question? i was thinking about doing this to clean up wiring

Most vid cards have the fan already plugged into the pcb of the card itself. Unless you changed the fan on yours. If you mean plug the vid cards extra power connection to the board, then; NO. NO. NO. Smoking Hellfire NO, Don't even think about it.

At first I was thinking you would actually need to make your own connector to do something like that. But then I looked around and, realized I have a number 3 pin to 4 pin fan connectors, with both male and female 4 pin connectors, laying around that you could physically connect up that way. just plz don't do that.
