I was planning on buying an Asus A7V266 mobo (any better suggestions are welcomed) and had a question. The board has three fan connectors, one of which is used by the northbridge. So if my case comes with 2 fans, and the CPU uses one connection on the board, how do I connect the other 2? I always hear of people having more than 3 or 4 fans hooked up to their mobo, how do they do it? Thanks a lot in advance!

Get fans that power of the HDD/CD type power leads, or an adaptor. The only problem is that you will not be able to get things like MotherBoard Monitor to monitor these fans.

Thanks. I see that you're saying some use the 4-pin power supply from the PSU. On top of that, these 'adapters' you say, would you recommend a Y-splitter? Monitoring shouldn't be a problem. Thanks again.

A Y splitter will work perfectly. Might not be a bad idea to get an extra one should you need to plug in another component (like a second harddrive or additional CDRW drive)at a later time.

My exhaust fan and intake fan use a Y-splitter to connect to the PSU (actually, it kind of taps into the PSU line for another device i think).

My slot dual-fan gets powered through a tap too, i forget from where...

My mobo has 4 fan connectors. one is for the processor, another one is supposedly for the rdram fan, and the other two are system fans...but i only use the processor fan connector (of course). I will probably use the other fan connectors when i upgrade my fans (my fans are the 3-pin kind, but the mobo needs 4-pin connectors)

I have a ABIT KR7A RAID mobo, which comes with five fan headers, one of which is used by the VIA KT266A fan. I actually have plugged into the mobo the 80mm rear exhaust fan, the cpu fan and the videocard's GPU fan, while the front intake 120mm fan and the top 80mm blowhole fan are connected to the dvd and cd burner power supply lines with those pass-trough 3-to-4 pins adapters.
I could't connect the 120mm fan to a mobo header cause of it's too great power requiremente (burning a fan header on the mobo is NOT a nice thing) ;)

Thanks a lot guys, this is a great help forum. I found out the fans have the 4 pin connectors (with 5, 12, and ground rails) so I can just get a normal splitter and hook them up to the PSU. Thanks again!
