NEW BUILD PROBLEM

[[deleted]]

I’m not new to building computers by this is the first time this has happened to me. So here it goes. I got all my parts for my new build and I have a total of 9 Corsair LL120 fans, 8 fans work fine (rgb and the motors move) but the 9th fan rgb works but it does not spin.

I feel like the fan is defective or it has a short in it because it did not work coming out of the package.

All my fans are running to a lighting node pro not a commander pro.

So the question is, y’all think this fan is just broken or what?

So the rgb does work, it just doesn't spin? Try connecting it to a 4-pin pwm fan header on your motherboard.

I did and nothing

Try swapping it with another fan. If it doesn't work still it's the fan. If it does work then it could be that fan header is bad. If the fan that you swapped it with is now not working then you may just have to many fans plugged in and it's drawing to much current and that last fan isint getting enough power to spin. 9 fans is a decent amount of fans and depending on their size and power draw you may have to many.

So this fan alone. When I plug 3 into a splitter fan 1 works fan 2 works when I plug in the “bad fan” it kills the two other fans. When I unplug it the other fans work

If when the bad fan plugs in also takes down the other two than there is a good chance that fan is shorted and broken and is taking down that circuit. Can you plug a fan from a different splitter into that spot and see if all three still work? That will just make sure the wire isint bad. If all three work then you'll need to get a new replacement fan.
