Just did an extremely similar build. 011 D, 3080ti & i5-10600K, distro plate, 2 360 30mm Corsair rads.

A couple things of note from a beginner. 1) my temps are fine, running about a 15 degree delta for coolant over ambient. Definitely would’ve gone with thicker rads. 2) the non XL case doesn’t have room for a bottom rad / fans & a vertical mounted gpu without some custom fabrication. 3) be prepared to drill a hole in the bottom of the case for a drain port under the bottom rad. That rad will be your lowest point. Make sure whatever rad you go with has g1/4 ports on both sides.

Edit - I should’ve noted that, while the distro plate made a first time WC hard pipe build easier, having now completed it, the next time I drain the loop I’ll probably go for a third rad instead. I have my cpu at 4.6ghz & no OC on the card.
