Black with white stripe from the adapter to yellow on the fan.
Black to black.
Thanks Alesh. I have seen a few posts now and several are different on the wiring process.
This quote from another on the forum was what threw me and I had no idea what wires do what,
"It sounds counter intuitive but I believe you want to run the black wire from the power block to the red wire on the fan and the white wire on the power block to the black wire of the fan. A/c uses black as hot wire but d/c uses red as hot wire. Basically switch one set of connections."
edit... Gave a 3 wire fan I had a test, black to black, black/white to yellow..it blew the fan and smoke came out. 3 wire fan has black, red and yellow wires. Is a 3 wire fan different than a 4 wire fan? I will be using a 4 wire fan for the main build...if i can find out the order to wire it.
