so I have the fan mount for my active cooling for the head of my E3D V6, but was wondering how you guys wired it.
-did you splice it to the other two fans that are already on the E3d v6 , and the one on the back of the stepper?
-- if so do I need a bigger power supply?
-is there a way to plug this active cooling fan to the board some where?
im running an SD3
hi ryan i do not have the e3d yet that being said iad installed a cooling fan untill it broke i did 2 dpiced from the cooiling fan for the extruder one made it so that fan could be disconnected and the other was to the cooling fan so it was easier to maintain
im confused,
lack of a comma or period, might be my issue,
so it wont bog down, to splice into the wiring, that my other fans are splice together,
im just wondering if its a good idea to splice three fans together.
You can run 3 fans spliced together just fine. What three fans do you have?
1. Extruder motor fan
2. E3d cooling fan
3. Cooling fan on your board
Those 3 will be fine.

1 & 2 yes,
no fan on my board.
the fan im going to use for material cooling is identical to the E3D fan
So you are adding a nozzle fan? That should be be G-code controlled unless you plan to only print PLA. If you'd like it to be G-code controlled you would connect to the fan header on the board and make a small firmware change. The process has been covered but you'll have to search.
You should have a fan on your board to keep the stepper drivers cool.

oh man, lol
and I thought I was starting to understand this stuff.

yeah it a nozzle fan,
I was looking up the gcode controlling the fan.
it requires another board?
this isn't just a list of code to add?
and ardiuno*spelling, flash needs to happen?
You have a Printerboard you don't need another board. When I get some time I'll search for the thread that covers the process and post a link.
cool thanks man.
ill keep looking too maybe try to educate myself before I go to you link.
Not the one I was looking for but it is discussed here in the last few posts.

If I recall the pins are already soldered on some of the Printerboards. So it maybe as simple as plugging the fan in. Otherwise you may need to solder on the pins and activate it in the firmware.

so from what I read I do have to wire up the mosfet?
or are you saying this may already exist on my board?
I am of course even more confused.

Yes you are 
Sorry about that.
The printerboard (best I understand it) already has everything on it with possibly the header pins being the exception. Then it is just a firmware issue once a fan is connected to the board to activate those pins.
here is what im looking at
do I wire onto anything you can see?
See right between the two sets of white plugs where it says fan. You'll need to solder pins to the board or wires.
how do I do that without frying the board or over heating it.
my soldering iron has a pit wore in it from the work I have done so far. so that is the only concentrated hot point on the iron.
You could buy a new tip for your iron or file that one to a point. I am guessing that if you are melting or damaging the tip you are using a big tip for bigger stuff. If you use a fine tip and keep it right where the solder is it should be fine.
