Tri-Band vs. Dual-Band allocation?

I set “always have fan on” and then “Apply”. It says that the setting is what I set when I go back to the normal page and then back to the Debug page. When I do that the setting seems to “stick”. No movement from the fan. I then reboot and still no fan. I look at the debug page and tThe fan has been set back to off. I’ve done that a few times. I’m not going to re-litigate this but even if this isn’t a “premier” or “top of the line” router it is certainly not a mainstream router. If someone wants WiFi 6 they can spend a lot less. Any tolerances, especially heat, being so close AND no fan is really nonsensical to me. You are genuinely trying to help. I appreciate that.  So that’s the last I will say about that. It’s just my opinion.

What I wish is that there were a hard switch on the case that would be a direct indication that there is a physical problem when the fan did not turn on. The router seems to be running cooler today so I’m assuming I was stressing it hard yesterday with me constantly setting, resetting and testing it over and over over a handful of hours.
