I think you badly mounted cooler block because temperature jumped instantly under load. Try to remount it. In normal operation (not using AC), CPU temperature under load should rise from idle temp much slower and reach that temperature after a minute or even more time. Also after short period of running full load (<1min) your cooler should be able to lower CPU temperature back to idle in few seconds. That would mean that you properly mounted AIO cooler on CPU.

Some hardware might not like a below zero degrees intake air. For example my supermicro chassis have an "unsigned char" inlet temperature sensor and treats this as a critical error of 255°C overheating

I love the moments of levity! (ice cream, etc.)
I would suggest that when discussing computer parts in speech skip reading all the part labels. "AMD Ryzen 7 38000XT" is a lot to say and kind of kills the momentum of the video. Especially when I can see it on screen.
