Someone should have really bad airflow to hit 50+ temps.

I have close to 50°C at 1.4V here. When I use 1.45V, it goes above 50°C. The airflow is pretty good, there's a tower air-cooler moving air in the area and the front case fans are close.

It's two sticks of 16GB 2400MHz CL17 ECC server memory. This means each memory stick has 18 memory chips on it. It has no heatspreaders. It uses Samsung B-die, and it can do 3200MHz at 1.45V and 3133MHz at 1.4V. I use it at 3133MHz with 14-17-15-31 timings and 1.4V. When I run a memory stress test or I run prime95, the warmer stick hits 48°C and the other one 46°C.

If I got r5 3600x or r7 3700x, would my current 2x8GB 3000MHz CL16 be fine, or is that considering slow for ryzen ?

Crucial BLS2K16G4D32AESE, overclock from 3200 to 3733 without voltage increase. Stable everywhere, including torture tests, karhu and memtest86 over night.
All current settings in the scan below in the "curr" column, expect for RFC which is 560, not 653 (see dram memtest screenshots).
