Yes, that's typical.

GPU appears fine. CPU seems to be under load with about 70% utilization; temperatures look acceptable. Your AIO's fan and pump seem to be running at higher speeds, possibly due to the stress test. If everything is installed correctly, those metrics should improve once idle mode resumes. The pair of temperatures on your board reads 127°C—uncertain if the nearby 37°C relates to it. If the 127°C occurs during the stress test, check if it returns to normal after stopping the test. Such a reading is roughly 260°F, which most standard PC parts can't handle.
I'm curious if I'm playing XPLANE 11 and when I connect to the IVAO server, I begin experiencing frame drops lasting about 1 to 2 seconds.
You're playing a game named Xplane 11, and you've adjusted the AI and pump settings to function at a high level.
