Yes. On top of the print head there should be 3 wires related to temperature: power, ground, signal. That ground is perfect. It's probably the black wire on the black/red/yellow twisted cable but I'm not 100% certain. The fan also has a ground wire (I think).

    It looks like I am running into this issue with the dual fan upgrade I did.

    I am curious what your solution was to get this resolved?

    I wrapped the fan wires into the plastic wrap above the print head. That's probably the culprit in my case. On the good side, the fan wires are outside the print head so re-routing them away shouldn't be terrible (just need some clever way to secure things on there)

    Are there any good, locally available (auto shop, etc?) means to wrap the wires to reduce the PWM noise? I have the wires in heat shrink tubing up to the last 4 inches, where the wire leads come into the connector.
