first thermal and noise tests
one hour stress test running CPU and GPU in parallel, case fans set to 50% RPM
3800X @ 100% PPT: ΔT=62°C
RTX2070 @ 100% TDP: ΔT=40°C
noise levels measurement is not totally accurate because we had a lot of traffic on the street besides the office today...
Anyway, the system is pretty quiet even under load. The most noisy part is the fan from the AMD Wraith Prism which I used together with the Thermalright AXP90... better should have used the IS-60 cooler with the big and silent fan...
It is very interesting that the speed of the case fans doesn't make a big difference concerning CPU thermals. It's just +/- 2°C between the lowest and the highest fan speed setting and comparable with an open air build. Most importantly - as for every case I have tested so far - is a good CPU cooler with a good and silent fan on it! The GPU clearly benefits from the bottom fan. Temperatures dropped by 6°C on the highest fan setting.
OT but also interesting: my BIG1 design achieves the same CPU thermal performance despite only using one single 120mm fan. Guess I did something right there.
