I want to do the 12v fan mod, but I would like to install a toggle switch so I can switch from 5v to 12v when needed..


Problem is, I have never worked with toggle switches, and dont even know where to start uhh.gif

I am confused with the whole concept (Sorry if it is really easy I just cant really grasp it i guess)

If someone could please point me in the right direction with a tutorial, maybe some pics, ANYTHING you think will help me with this...

I also would like to know what type of toggle to use or which do you recommend?

Thanks in Advance for the help...

get a SPDT switch [single pole, double throw] connect the ground wire from the fan, to the middle pole. Connect a wire from ur 12v ground [anywhear on the case] to one of the outside poles. And connect the normal 7v ground to the opposite pole. This way, if you push it one way, you will enable the 7v, and the other way will enable the 12v.


Here are examples of various SPDT switches. Personally i prefer rocker switches:

you need to put your fans positive wire to that ground wire shown in pic. ph34r.gif if you put wires like in pic you will fry your box and psu...

ok, so let me see if I understand this:

Connect a wire to the middle post, ground it to the metal casing
Connect the ground wire, that i would have connected under the mobo (for 12v) to 1 of the other poles
Then, cut the remaining ground wire on the fan plug and connect it to the other pole

Am I getting the idea right?

You can also put a switch between to points on a resistor.

No one has a clue in here do they? wink.gif The diagram is almost correct EXCEPT for the absolute and utter fact that the 'to ground' needs to be changed to 'to fans + wires' (like jopotus stated) that will let you run the fans at either 5v or 12v depending on where the switch is at. Wiring it up like the diagram is will only get you a nice 5v or 12v short, depending on where the switch is at and isn't going to kill the 360, but it's no good for it none the less.

The fans will startup at 5v just fine.

Here's what you need to do in order to have the fans run at 5v/12v with a switch.
