[3/6 Riing RGB 12 TT premium edition]

Hey guys !

First of all, sorry for my bad english :]

So, I bought 2x3 fans for my new pc case (H440).

Since i'm a noob, I asked someone to install them.

The guy did, and after the first test, only one of the two controller were actualy detected by the software.

I tested everything (driver, cleaning, switching port) and even take my whole Pc to a professionnal who didnt found a problem at all.

My MOBO is an Asus x99 Deluxe, everything is connected correctly since the non recognized fan are red and turn.

 

What could be the problem ?

If one of my controller dead, can i get another free of charge ?

I'm already asking myself if I should return them and put on the basic case fan..

Thank for your future help !
