Yeah. I meant looking at the back of the plug it would be yellow/red/black.

So here is my fan plug. Right=black. Middle=red?
Also got my electrical parts (switches resistors ect) today. Just waiting on my aluminum for the cover.

The heatsinks alone were 22 pounds with my build. It encouraged me to mount the drivers remotely, that and how warm summer is here. Your build looks very solid and professional!

US guys have almost all a/c unit so heat is not a big concern I guess!
Personally I put mine on the top of my growbox outside because it produce more heat than my cob @1400mA I guess and where I live heat is a concern since May to october and a pita in july and august!...and no a/c where I grow...but we consider to buy a movable one a bit oversized because of the cob but I am not sure it is needed...cobs don't produce much heat!?!

Just to be sure.....I'm wiring these cobs in series right? Not sure why I just thought about this. I wired my fans parallel which I think is ok. They only draw .09a.

Yes, series with the drivers you're using.

Agreed.

If i turn them then it pulls air INTO the heatsink. I had them the other way originally. I thought the idea was to pull the heat AWAY from the heatsinks.

NO, you want to push air into the heatsink, has been documented countless times as the preferred way in your configuration........some manufacturers pull the heat away to get ul/etl certs === design limitations.

Cobs mounted. Ugh. Time consuming process of squeeging Arctic silver 5. I taped each one off and used a razor blade to squeegy it. Made 3.5 grams do all 8 LEDs.

Great googamoonga this thing is bright!!!! Oh and pulling air in is way better. Nice even flow coming out the sides of the heat sinks. Dimmin works good. Lol I think I coulda stuck a 75k in there! Way brighter than my 400mh at 50%. Now to hang it.

Here it is hanging. Perfectly centered. The light is way more even now. The pictures don't do it justice. Big thanks to Rahz and everybody for their help!
