Hey, I would like to understand why am I not facing errors despite the dimms still crossing the 55°C "barrier"?

Since I bought this fan cooler, my dimms temps are still crossing 55°C + all the way to 60.25°C during stress tests, but aren't showing tRFC + tREFI tuning related errors anymore. How can we explain this?

Here's a pic of Zentimings + TM5 (I plan on running this again overnight but I usually start facing temp related errors really early the moment I start tuning refresh timings).

Also, my dimms are running super hot with that board, I still don't really understand if that's an Asrock issue compared to my previous MSI/Asus boards or the terminations not being set up correctly (ProcODT going automatically to 53 ohms the moment I enable EXPO).

Any knowledge would be much appreciated 🙏
