Planning out my new loop for the Ryzen 5950, I'm finding that a top mounted, crossflow radiator would be ideal for routing and likely cooling purposes. That said, I'm not finding very many options for crossflow, at least in 420 size - just HW Labs and Alphacool. Any opinions out there between the Black Ice Nemesis 420GTS XFlow and the Alphacool NexXxOS XT 45 X-Flow 420? Am I missing a top performer / popular model by not looking more at 360 models?
