hi. i used the phat ground cable to the alt point for D and for C point i used green phat cable (not cut) soldered to slim blue cable (not cut) and wrapped around the fan.
I had a trinity that kept doing this for near a week and i was almost finished trying til i did this setup and within 30secs i had my cpu key through the NETWORK.
It is really annoying but trying different cables etc is the best way, i tried different sizes from 120cm down to the smallest i could get it and nothing so its not always gonna work with the sizes, its the cables used that count too.
Some might say I'm talking bull but it does clearly say their all different to their own and different setups required for different timing cause their not the same. lucky you lot with just different cable sizes tho

.
Hope this helps you mate. I will post a video of my setup when i get the time cos the second it booted for me i turned it off and started recording a video while rebooting it back up as prove lol.
