5800X3D aircooled (Be Quiet Dark Rock Pro 3) with -25 on all Cores (no other changes).
When i stress (CPU-Z all Cores) the CPU for about 15 minutes, i maximum get to 75,3 °C (highest Value i ever had with this CPU / System).
[The AMD 1600X i had before was max ~ 66°C in the same System but with stock settings]
Motherboard: Asus CH VI (x370)
Power: 850 Watt be quiet! Dark Power 13
Case: Thermaltake Core X 5 (all sides mesh / Motherboard Horzontal - i hate this Vertical Mounting especially with the big CPU air Cooler and the heavy air cooled Graphic Cards).
The Deepcool AS500 is smaller then my Cooler, but with 75W PPT you should get better Temperatures i think.
How is the airflow in your System? Maybe you have additional °C by using a closed, small or full packed Case?
