360mm rad enough for 3080+5900x running with stock.

Case in question is Eclipse p500a. Can either use 420mm rad in front or 360mm rad uptop. Just don't want to spend more $$ on 45mm 420mm rad if not necessary.

Please give me your thoughts, still rather new to water cooling so the questions.

I ran a heavily overclocked Titan XP and a 3900X on a single 360mm radiator with no issues. The 3080 has a higher TDP and generally runs hotter, but I suspect you'll be fine either way if the primary use case for you is gaming. My load temperatures in games were around 50C CPU and 40-45C GPU. The 12-core AMD CPUs are very power efficient in most use cases, they really only pull tons of watts (and thus heat) when you load up all 12 cores in a workload like encoding.

I personally wouldn’t go with a single 360 with those components since you’ll need to make sacrifices to cooling performance and/or acoustics. That 420 would be a better option or better yet if you can fit 2 360s then that would be ideal.

I’m running a 3090 and 5900x on a 360mm rad surface area (240mm + 120mm) and have no issues at stock clocks. Delta for the loop is about 19-20 over ambient on load.

running slim 20mm radiators abs slim fans.
