AP6 Pro temperature

Regarding the AP6 Pro temperature that has recently been implemented for UI output:

What is a typical expected temperature? And is it average, min, max or median for temp sensors within the AP?

I see 73-74 deg C (164-165 F) at idle (5-10 % load) in ambient room temperature around 22-24 deg C (will probably be slightly higher closer to the ceiling).

fwiw my ap6 pros are 131f and 139f, ambient of 69f. Route10 sits at 103f.

Mine just hovered around ~73 C when having constant download around 100 mbit/s (i saw both ~50 and 20% tx usage of 5 ghz band). Similar room temp 22-24 C

It quickly went down to ~65 c when idle and now around 64.

Mine is wall mounted with a few mm extra distance (I used top cover from cable canal).

Seems like I should try to lower my readings by adding a bit of distance too. The bracket is flush mounted to the ceiling right now.

I did some testing and added 4mm thick pieces of plexiglass around the screws to add some distance between the mounting bracket and the ceiling. However, that didn’t change the temperature whatsoever.

I might do some more experimenting and replace the plexiglass pieces with some nylon washers or standoffs, and increase the distance a few mm more, while minimizing the footprint vs the bracket and ceiling. See if I can come to a suitable trade off between maintaining the lovely aesthetics of the AP6 Pro while adding some airflow to get the temp down a bit, just for the fun of it.

The AP has got a heatsink on the backside, which should provide very good heat transfer, but I guess the bracket, in combination with the ceiling mount, provides too much unwanted insulation. So, we’ll see if I’ll extend the experimenting to also open up the bracket somewhat, while still maintaining sufficient rigidity.

I should probably have mentioned that I run mine with 20dBm for 2.4GHz and 23dBm for 5GHz powered by POE (48V) since it might affect the temperature.

I managed to only place small distances where I screwed the mounting to the wall , but I don’t really know how much of a difference it makes.

Some photos in case anybody is interested :slight_smile: It was supposed to be a temporary placement to measure coverage but it gives good whole house WIFI including the garden so it will probably stay until it is time to put some paint on the wall.

Mine is at 172F. :sweat_smile:

Lab report:

I added some white nylon spacers, M3 (or might have been M4) x 8 mm, placed between the mounting bracket and the ceiling, and changed to suitable screws, and drilled appr. 10-12 holes (new or increased size) through the mounting bracket, while still maintaining sufficient rigidity. I drilled and also used rotary bits as well. Bracket is screwed to the ceiling with four spacers and screws.

I managed to get the temp down apprs. 3 deg C (from 73-74 to 70-71) in the idle case with similar ambient conditions. I have also seen faster temperature drop after bursts of iperf3 runs as well as even lower temperatures that I haven’t been able to reach in the “stock” config. By this there is a bit of airflow introduced and better possibility for the backside heatsink to get rid of heat.

Aesthetics is not so negatively impacted.

Overall, cooling is improved, but if it matters at all with respect to MTBF is of course hard to say. :sweat_smile: And, if it was worth it, probably not :sweat_smile: But, at least I tried.

@ebuckland81

How does this look on the ceiling itself?

@Beaker, not so bad.

Some of you may have remember me done an experiment earlier Adding a heatsink - #30 by dxyong

Now that I have moved to my new place, unfortunately I am still not comfortable fixing the AP on wall or ceiling without any cooling aids, right now it sats on my TV console, on a mobile phone holder and an USB fan at the back, active cooling like this is not ideal for long run as these fans can fail anytime if running at 24x7, but at least I can replace it as soon as I notice it. I am still looking around to see who can come out with a better solution than this right now :joy: Btw it’s at 50+C which I think alright instead of 70+ like ebuck facing

Oh, gosh, that’s a massive cooling aid for the AP :grin:

You’re exaggerating and being overly cautious. Yes, they get hot but not hot enough to burn down your house. Paper for example must reach 451°F (233°C) to catch on fire. Wood has to reach 572°F (300°C) before catching on fire. Knowing the coverage pattern of that access point, you’re losing a lot of performance having it like that.

Not to mention the orientation of the fan which, while hard to determine, does appear to be blowing towards the radiating heat. It should be reversed to pull the heat away from the AP.

I think you’re ok to mount bud. Alibaba isn’t going anywhere for future projects haha.

Impossible to infer a direction from the picture. Anyway, pushing cooler air towards the heatsink would probably be the better choice in this setup, as a push setup would better disturb the boundary layer of hot air than a pull setup. :grin:

Interesting how the cooling works out, in an engineering perspective, but agree on it being a bit to cautious. :joy:

Recall that if you have DPI active, it’s running on the APs and is CPU-intensive.

In my case, perhaps with a limited number of clients, the DPI on or off shouldn’t make much of a difference, as the total system load hovers around only 6-12 % with DPI active.

Upon disabling DPI, it doesn’t make much of a difference indeed. Actually, I’m not even sure if DPI is actually disabled as the DPI statistics keeps on updating.

Edit: Seems like the DPI might not be fully disabled. Data is less than for DPI on, but still outputs some non-zero statistics. Added a separate report here:
