Yes I have several and no they aren't (although I seem to recall my nanoHD got a lot hotter when I had it ceiling mounted), but that doesn't mean yours is defective or a fire risk, every WAP is designed differently.  Some dissipate the heat over a large area while others it can be more focused like you identified. Different SoC can dissipate different amounts of heat too.

My core network switch on the other hand despite having active cooling has been too hot to touch many times, and my N100 router PC always is as the SoC is cooled by the case.

Cheers for the info

I presume you are doing some intensive networking though? Your internet connection must be very fast?

I only have a 70Mb internet connection & not much traffic on my private network

I had a 10Gbit SFP+ to RJ45 in there at one point, those things get REAL toasty as they pull several watts in a really small space.

That's why its hard to judge, as its not how much power they are pulling, its how much space they are dissipating the waste heat over and how effectively.

Another prime example are USB sticks, if you get the fast ones that do 100MB/s they get too hot to touch also.  Even microSD cards it was a real shock the first time I took a modern one out right after writing lots of data to it.

Although the really impressive one is the Xbox Series SSD expansion, as its a proper PCIe 3 SSD inside a custom caddy designed to transfer the heat into the Xbox Series consoles itself.  So if you take it out immediately after heavy use, its probably 50C+ and would easily burn you if you touched the metal for more than a second.  You just get used to some tech getting really hot when you've had a lot of it over the years.

Dude, on your internet statistics page you are pulling 4900Mbs combined, your an enterprise user, your equipment is gonna be hot 

[Alex Atkin UK]

What statistics page?  All that hardware is mostly idle 99% of the time and the N100 specifically is always going to be physically hot as even when idle as the CPU is directly connected to the case so all the heat is going into the case.

In your bio, under your comments: "My Broadband History & Ping Monitors"

Yes that is another problem the device could fail soon outside return period  :'(

I see a lot of APs have DFS monitoring run continually and radio optimisation listening.

If you mean the speedtest.net results then that's literally a torture test and only ever hit 2Gbit.  That's background noise to a 10Gbit switch and doesn't make a whole lot of difference to the router temperature either.

Surely all routers/APs running on a DFS channel have DFS monitoring constantly running, or they wouldn't be able to detect a DFS event.

I have no idea what load radio optimisation would put on a device, I can't imagine it would be much compared to the software bridging that happens during actual data transfer.

speedtest.net

Yes. I added 3 routers by accident. You seem to have 2 on 2nd look. 3176Mb, that's 45 times my connection

APs have DFS monitoring

The APs shouldn't heat up to this extent no matter the features imo

Still, reception shouldn't heat up like transmission does.

You're welcome to that opinion, but reality does not concur.   Electrical appliances get hot and some dissipate it different to others, giving the illusion they aren't getting as hot when they actually are but its not transferring primarily to a single spot on the case.

[MaximusPrime]

You're welcome to that opinion

I think you're lax with your fire safety imo

Do you have fire alarms & suitable extinguishers?

Yes, and they get tested once a year.

Sent it back to the supplier

Supplier said the unit got "alarmingly hot" - left it on overnight

Knew it was dangerous 

[Alex Atkin UK]

Unless they compared it to another one and it was different, that means nothing.  The supplier has no idea how hot its supposed to get, only the manufacturer knows that.
