Great question! I just now plugged in a USB temp sensor to get the ambient right. Its hanging about 20cm above floor level in front of the case, about level with the CPU cooler.
Here are some readings, with 4x 16Gb dimms, the 7252, a Gigabyte 7000s 1TB NVMe drive (rated 6.5 watts) and a Radeon 7790 in the box. However most of the heat from the latter two will likely go upwards (which is away from the CPU section, since my case is inverted) and exit through the top vent. Fans are the stock case fans, 2 in the front and one behind the CPU. CPU cooler is SNK-P0064AP4.
@jtredux you’ll see I haven’t changed the thresholds yet, I’ll look into that next. Thanks for the info.

NB: FAN4 is actually 3 fans - currently all three pre-installed case fans, two in the front and one behind the CPU, are controlled through the case’s fan controller (which is set to act as a PWM repeater - though I haven’t verified its function). FAN5 is the CPU.
I find it remarkable that the CPU at idle is only 4 degrees above ambient. This is with the pre-applied stock thermal paste. However, the other temps are comparably a lot higher.
After running mprime on all cores until temps stabilize:

At this stage all cores oscillate between 3.0 and 3.19 GHz (rated range is 3.1-3.2). cTDP is untouched, so I believe it is effectively at 125w.
Fan policy is set to “optimal” in BMC. Case fans (FAN4) max out at 1000rpm, and the CPU fan (FAN5) at 3800rpm, suggesting they run at 56% and 48%, respectively. So there is definitely headroom. I’ve ordered two more case fans, when they arrive I plan to experiment with cooling zones.
So what to make of these temps? How do they compare to yours @Nefastor? At least at idle our systems should be sort of comparable.
