Something I have noticed at hand right now, don’t know if this is the right channel to ask.
I have an Asus Chromebox 3 at hand and I had its firmware updated to the latest one. Re-running the firmware command from the site hosted by MrChromebox gives this output.

If it helps, running lsb_release -a gives the following output.

Ever since I had upgraded it, the fan’s been running at full blow nonstop. I did a bit of searching around and found a github issue comment by MrChromebox himself saying that Chromeboxes before 2018 do not have an embedded chip that controls fans
→ Control fan on a Dell Chromebox 3010 (Intel Haswell / TRICKY) · Issue #410 · MrChromebox/firmware · GitHub
Would this be the same with my CN65 as well? I did not notice the fan sound before this upgrade though, so I do not believe this was something that was happening before I had upgraded the box.
Also, as stated in the headline. There’s no video output from the HDMI port of the Chromebox. This definitely was not an issue before, where I did have a terminal output from the box on my screen.
Edit: I forgot to add the sensor readings from lm-sensors. I ran sudo sensors and had this printed on my terminal:

I do not think the loudness of the fan can be justified at temps this low. I can put a piece of paper an inch off of the vents and they get pushed back.
