Please read through the watercooling sticky- it is linked in my signature below.
As for directly addressing your question- yes, most thick 360 rads would work in this scenario. The 560 Ti's are around 165-170 watts, and most 360 rads will support a load of 525-600 watts easily with 1200-1800 rpm fans. I am betting you'll have other questions about your loop, so give the sticky a good read-through and let us know what else you need help with.
Thanks and welcome to the WC forum.
