Hi there,
I have a Threadripper 3960x on an Asus Prime TRX40-Pro mobo, cooled by a Noctua NH-U14S TR4-SP3.
I have performed the 9 small + 4 big points method suggested by Noctua for the thermal paste application:

The case has two fans at the front and one fan at the back, all 12 cm in diameter.

Yesterday, we have run ANSYS Fluent in parallel on all 24 cores for about 4 hours straight:

It was during mid-day, the room was air-conditioned and I guess that the ambient temperature was around 25 degrees Celcius.
AMD Ryzen Master's temperature reading was around 78 degrees Celcius during that run.
Here is a screenshot:

My question is, is this temperature level expected? Should the CPU run cooler with these settings?

Thanks in advance,
