H100i detected but fans NOT detected?

Hi guys, I have recently set up my H100i and when I open the Corsair Link software I can see the various fans for my MOBO but no H100i fans?



I'm pretty sure I have connected the fans correctly:

2 fans into the y connector which goes into the head of the pump. The 3 pin head from the pump then goes into the main CPU fan slot on my motherboard.



It's a strange issue as when I go into 'Options' on the Link software I can clearly see the 'Corsair Hydro H100i USB' is detected. Firmware version is 1.0.7.



Any suggestions on what I am doing wrong?



My specs are:

i7 3820

Sabertooth x79



I have a few other hardware monitors installed on my computer too.



Thanks in advance.
