]]>]]>Is 5 volts on a 40 millimeter fan enough to keep the layer cool?
Not sure about that one, I've only ever used 12v.
I'm sure some of the guys over on the Voltivo forum have tapped 12v from the mainboard.
It would have to be a transistor that works in the 0 to 5V range, and would need a current limiting resistor on the gate.

I try and support the people doing the innovation so I like buying genuine. my e3d v6 and my cyclops are genuine I got them from matterhakers
Totally agree.
Be careful tapping into the 12v. I've heard of people wrecking the mainboard attempting that.
It was for that reason I used an external 12v power supply for my E3D fan.
I used this adapter so I did not have to touch anything directly on the original for the 12 v source. I ended up using t-tap type connectors to "tap" into the lines on the extension.
]]>These are just standard CPU/PC fans, and have a 3 pin connector with red,yellow, and black wires. Red is your positive voltage (could be anything up to about 12V). Black is negative/GND. The yellow wire is a tachometer/RPM sensor.
This color scheme can be confusing, because usually yellow wires in a computer are +12V.
They are variable fans, meaning the more voltage you supply, the faster they turn. Motherboards control them by turning them up and down as needed to match a set RPM.
If you hook the red and black up to constant voltage, and ignore the yellow, it will just run continuously.
More interesting would be to hook it up to the fan sensor on the extruder, and be able to control the speed with G-code. I don't know for sure, but I think the extruder fan runs off 5 volts, so you won't get the full power of the fan.
Someone else who has done that mod might be able to chime in.
