Can't help with your query, but one thing you might like to consider is that the USB 2 header to micro USB cable which comes with the SL V2 fans is really short, 42 cm. Too short for my Lancool III to go from the motherboard USB header, round the back and plug into the controller. There was no slack for cable management, so picked up a 50cm one online.
I can only imagine a V3000 will be more of an issue with the short cable?
