NZXT AER 2 RGB Fans - RGB not working in 2/4 of them?

[Alex Skov]

Hi! So i recently build my first desktop, and i've stumbled across a problem with getting the rgb in my case fans to work...
Prior to building i bought 2 NZXT AER 2 RGB Fans, to match the 2 NZXT case fans already installed in my case :)
After getting the pc put together, i noticed that there wasnt an input for the rgb cables, leading from my 2 rgb fans? I tried plugging them directly into the rgb controller input on my motherboard, but it made a sort of screaming sound when booted, so i unplugged quickly!

I googled around, and learned that i needed a NZXT Fan controller hub thingy, so i ordered one + 2 extra rgb fans, so that id have 4 ;)
They showed up, i wired everything up and BOOM, 2 of them ligthing up like in attached pics (one of them lighting red in 2 sides, one of them blue)

Now the logical explanation would be that i fried em, when they made the screaming sound BUT, the weird thing is, that its only one of the the ones that were screaming that is acting like this (The blue one), while the other screaming one (red one) is working perfectly fine?

I've tried wiring them all different kinds of ways into the Fan controller, including completely disconnecting the 2 working ones, and just wiring the red/blue ones directly into the controller, but with same results. Also tried different configs with either of them being the direct connection, and the rest being "passthrougs", but all with same results...

I've google around for days, but with no luck, so now im trying here... Are my fans just toast? (And if so WHY?! One of the ones not lighting correctly came like that out the box then?)
Please help thx
