With the H100i do i have to plug the cable in that goes into the USB 2.0 or do I only need that if i wish to use Corsair Link?
The Usb 2.0 cable is not for corsair link. Corsair link is a different cable. The usb 2.0 cable allows you to control it directly from your os. To my knowledge if you simply plug the fans into cpu headers then connect the pump to the sata power. You should be fine. If you hae an extra header though just plug it in. It is nice to have. Alos wen you boot the machine put your finger on the pump to make sure it is running.
Okay, thank you!!!!!!!
