I Purchased the 'EK-MLC Phoenix' with the 360 radiator option, from Overclockers a few weeks ago.
I also have the one before it, the 'Predator' with the 360 radiator option, and a QDC water block
on my GPU (1070) as well.
I think they are great units, never had any trouble, with either of them.
Both are very quiet, and excellent at keeping temperatures under control.
And you also have the option, to add in a QDC GPU water block in the future, if you
so wish.
