No bro. Cut those molex straight off and strip the wires an 1/8".
I'm assuming black/blue is hot/neutral or vice versa.
Yellows signal probably and green maybe ground.
You need to have exposed wires on both the fan and the plug.
Plug the plug in and use the two wires you expose to touch the black and blue and see what way it needs to be to spin. If it doesn't, then try other combinations with the yellow and green. It might even be black and yellow for all I know. But certainly two of those wires on the fan are your pos and neg.

Your power supply is probably 12V 1amp, right?
That fan only uses 0.16 amp I think so you should be able to use it for literally 6-7 fans. Better to probably use 4-5 though so its spinning fast and keeps those heatsinks cool.

Yes is 12v 2.0A and will connect 4 fans. I’ll use this too, you said connect the hub wires and test?

This is frustrating, i tried the plug and the hub with another fan and works. Anyone of the 4 artic with any wire color combination work! I dont think that all those are bad its like impossible :/

Oh damn it's 2amps? That's too powerful. Your fans say right on the Front kg them 0.16amp.

What's this Hub connected to? Is the other molex on the end of a fan?

I tried with a 0.5amp plug and nothing. Dont know what happen!

One great thing is I build everything and its alive

Test about 10min at 100% and feels a little warm, at 50% less warm. But I cant use withou fans right?

Tomorrow i’ll go to a electronic store and ask for Help about, I really want to use the light and give to the girls the last week of great Light!

The hub is conected to the plug and I can use few Thermaltake fans i have for test. But with the arctics doesnt. Even with the 4 fans nothing happen.

OMG man.... Like I said the first time... The fans are NOT PINNED THE SAME.
CUT BOTH THE FUCKIN CONNECTOR AND THE HUB, CLEAN OFF AND STRIP ALL THE WIRES. TOUCH THE DIFFERENT WIRES TO THE LEADS UNTIL YOU FIGURE OUT WHICH COMBINATION WORKS TO GET THE FANS SPINNING. If it doesn't work, it's not like you can't re attach the hub and connector. Just cut a few inches down from it so you have some wire to work with.

All you're trying to do is connect the positive and negative from the plug side to the positive and negative of the fan. So you'll need to experiment until you figure out which is which.
The other TWO wires that won't be used are for computer purposes like for a Signal/5V and maybe a ground. Not needed to directly power your fans like you need for your light.

Airwalker16 · May 6, 2019

And absolutely DO NOT run your light without the fans. Those heatsinks are WAAAAAAAAAY too small and inadequate to cool the cobs without them running.

Thanks friend! Will try right now that!

TomBombadil420 · May 6, 2019

Nothing works, any color combination, direct fan to plug nothing. I think they’re fried or something

((

I have to look 4 fans and see how to install to heatsinks.

Airwalker16 · May 6, 2019

Not done man. And once again. You're hooking up all 4 wires. Do you have a multimeter? If you do, find out what wire when you plug in the plug is giving you power, so you at least know that much.

Now you need to try hooking up the wires in any different combo.

All you've done in your picture is connect all the fans together.

So now use your plug and start touching the wires from it in different combos to those bundles of wires and see what makes them spin.
You're making this so much more difficult than it ever needed to be.

@CobKits you got a better way to explain it to this guy?

Airwalker16 · May 6, 2019

Please take a picture of your plug side and write here anything that's writtwritten on it, please.

Yellow is 12V and Black is Ground. You do NOT NEED blue and green.
So all you have to do is find out what wire combination on the plug side will make the fans spin when they interact with the Yellow and Black wires of the fans

Thanks for all your help my friend! I’m sure I fried, even one smoke I installed my loved ones thermaltake while I buy ones that make less noise. Everything is working. I can barely feel a little warm when I touch heatsinks and it's at 100% power.

And the plants (1 week to harvest) they grew with a not very good light and that's why they have that size, the one on the right is Indica and did not like the light 11/13 but the Sativa on the left accepted great, even so the buds did not grow as much as they should. I will plant new ones and I hope to harvest something much better

The left one is Sweet Pure CBD and the right Durga Mata II CBD.
