Hi just built my new pc and Cam is showing a Fan which is at 0 Rpm but i have nothing plugged into the hub it self. Is this part of Cam or a glitch or something i did wrong? RGB and all my fans work perfectly so not sure what it is
Fan 3 and RGB 3 - is for my back fan (x1)
Fan 1 and RGB 1 - is for my front fans (x3)
I have nothing in Fan 2 because its my kraken z73 and thats below
Again not sure if im doing anything wrong

Pic 1 of Cam : Link 1
Pic 2 of Cam : Link 2
Pic of Hub : Link 3

Any help would be great, again all works perfectly fine, i an control speeds of all my fans and rgb etc but just that 0rpm fan , i have 0 idea what it is
