I touched my cloud key gen 2 the other day (admittedly in the loft) and it was so hot I couldnt keep my hand on it!
I had a real quick look in the controller software and I couldn't see anywhere that reports the inner temps of the chips, have you seen it anywhere?
I also work for Virgin so if you are having an issue with something feel free to DM me and if I can help I will.

Not possible on the USG-3p security gateway, but the Cloud Key should show it.
You need to login via
ssh
and then runmca-ctrl -t dump
. Within that you'll see something like:"system-stats": { "cpu": "0", "mem": "5", "temps": { "Board (CPU)": "51", "Board (PHY)": "51", "CPU": "77", "PHY": "80" }, "uptime": "459056" },
But not all devices have the temp hardware installed... they will just fail silently if overheating.
I did find this patch for the USG-PRO https://github.com/teedog/usg-pro-snmp-temp but that only makes sense for that. The Security Gateway Pro has fans and active cooling, so of course it has a temperature sensor for the fans to be controlled. I haven't (and won't) used those patches on my USG-3P as I don't believe the hardware exists (I checked the chips on the circuit board and have identified them all and none contain a temperature sensor AFAICT.
I had thought that Virgin Media were shit (they still are, but not for the reason I thought they were)... but it turns out that Ubiquiti are shit.
The cooling design of the Unifi Security Gateway (USG-3P) is so bad that when my office gets too warm there is packet loss.
Office getting "too warm" seems to be "ambient temperature above 26'c", which is a lot of the time.
Then... if it really gets too warm, I lose the internet or the gateway believes I've gone from gigabit to ethernet speeds.
This is the edge of my network, so I've been measuring everything within the network and thought it was outside of my network... but nope, it's the perimeter itself.
And is this known? Yup.

Basically it's passive cooled, no air flow, and no heatsinks... so it overheats and fails!
I'm now running it with the case removed.
My solution though: I've ordered a 120mm Noctua 5v fan (I can power it from USB), and a couple of 140mm radiator mounts... the USG-3p is 130mm wide, so I'm going to use the mounts to build a cage around it and mount the fan on top to pull air out of the case, thus forcing airflow over the motherboard and chipset. The fan is so large (almost the same size as the USG-3P) that I can run this at very low speed and still cool it very effectively.
