    well the cheapest one is $10 and i need 6 of them so i dont want to pay 60 dollars worth of wires. Is there a cheaper way????

    the one for 14.95 can do 5 12V fans, I think that might be the cheapest way.

    if you wanna make one yourself, you have to either have 6 12v converters, or another cable that convert from your wall plug to 12v and be distributed among 6 computer plugs.

    How would you splice that cord to hook up to 4 of them?

    most fans have a male and female connectors, so you just need to keep connecting them in a serial way

    you connect the special power converter to the first fan using a 4 pin plug, if your fan has another 4 pin output, you need to connect that to your second fan and so on.

    if you fan has only 1 4 pin plug, you need to get a 4 pin splitter.

    the point is that the 14.95 adapter, can support up to 5 12V fans, but judging by you other thread, you can probably use 6 fans with it.

    if you still don't understand, I suggest going with 6 individual converters.

    isn't it possible to use a computer power supply?:confused: they run the fans inside the computer case, I would think one would work in this case, and you can just hit the switch on the back of the PS if you want them off

    That's a possibility, however, a good one goes for about $40+, and will probably contribute to the heat, but it's definitely the easiest solution, especially for 6 fans.

    If you've got a bunch of them laying around like I do (and any other computer nerd) it's practically free :D

    Well i thought i was going to be using HPS but a plan fell through so i am just using some CFLS instead. So instead of 6 fans i am only using 4. So which is the best way to hook up four 80mm fans up???

    I still think the best is using a computer power supply. Any of them will work as long as they have the molex connectors

    The power cable for 14.95 + some of these if needed...
