And finally the issue, I have the USB connected to the motherboard and am I correct saying I only need this to control the fan speeds of the 2 x SP120L fans because if so, issue resolved I can get a fan controller but if it has other use then I am screwed as it doesn't work unless I connect it while the PC is turned on. Every time I boot I have to disconnect and reconnect for Corsair Link 2 to recognise the fans and the pump.
Edit: The BIOS screen takes like 20 seconds when the USB is connected. Unplug it and it takes a second or 2.
The rpm wire is connected to the CPU fan header, correct?
Have you tried a different USB header to eliminate that as a possible cause?
Have you flashed the new firmware that was released? (Version 1.0.4)
Have you tried reinstalling Corsair Link? Are you using version 2.2.0?

You don't have to have any of the fans connected to the pump. You only connect them to the pump if you want to use Corsair Link to control the fan speed or adjust the speed profile. You also need the USB Link cable connected if you want to adjust the LED.
Another thing, are you using the latest BIOS for your motherboard?
