    Well that's basically what I don't want to do - cut and join 3 fan cables onto one header, as I don't want to ruin the fans (I'll do it if it's the only option or ditch the fan controller altogether)

    I have a couple of these
    http://www.pccasegear.com/index.php?main_page=product_info&cPath=19_197&products_id=17451

    not the nice bitfenix ones, something similar

    but they go to molex, which is useless to get to the fan controller.

    Also got one of these
    http://www.pccasegear.com/index.php?main_page=product_info&cPath=19_197&products_id=14690

    also useless, because the header is too short to fit into the connector on the fan controller.

    So can I safely pull off the short header and stick on one that will fit on there and connect that to the molex end of one of those bitfenix things? Essentially it's the same thing right?

    (edit 2: actually at a closer look they are very different - the molex to 3 pin adapter only has black/red, whereas all the other cables are black/red/yellow)

    I can probably use a header off NB cable extensions

    cheers!

    edit: so what I really want is something like that bitfenix thing but with a 3 pin header on the end instead of molex

    just snip the wires and solder/twist the wires together to get the combo you want

    I looked for exactly these things a while back. If you go to your local PC shop they should have the three pin fan splitters you require (I found mine at the local OrangeIT store). Nobody seemed to stock what was required. I have subsequently purchased some of these, but even they need a modded cable to connect them to a fan controller. They work well though.

    I think you need two of these or these better looking ones. Two of the first one (daisy chained) is how I run 3 Zalman ZM-F3's off of one Rheobus Extreme fan speed knob.

    I have a couple of those the problem is that even though that's the right thing, the header is too short to actually fit into the fan controller

    anyway, it doesn't matter as I've sold the fan controller

    but thanks for helping!

    you want 12v to run them at full speed, or 7v to undervolt and make them quieter...

    As the purchaser of previously mentioned fan controller, thanks for the links :)

    Just need to find out if the BitFenix 3 way connector only passes thru the RPM from one fan, not all 3.

    Hey I was just about to pm you but as you're in thread -
    I sent that off platinum at about 5pm so you should get it tomorrow :)

    OK another stupid question re those fan extensions it's just a wire though how does it regulate voltage? I don't really want to undervolt them but I guess 7V would be ok

    It just wires the fans to the 12v or 5v rails on the PSU...
    You can do it yourself by swapping the wires on any molex>fan cable converter thingy.

    not sure how the bitfenix ones are wired, but the the 5v one, in theory, would be easier to change to 12v...
