Alternative wall mount / temperature mod

I observed that from a certain temperature the power consumption of the AP increases sharply. By the way, the current Unifi 6 AP also did this.
The connected HP switch then reports “Power Delivery Over Current indication”.
It then briefly interrupts the PoE+ for safety. As a result, there are messages about sporadic reboots of the AP.
I wanted to improve the situation and mounted the AP on an aluminum rail. The air gap was filled by a thermal pad.

This is unnecessary in a cool environment. Screw replacement is not covered under warranty.
However, I was able to reduce temperature peaks this way.

Before: 
root@unifi:~# ssh root@172.27.1.242 -t "cat /sys/class/thermal/thermal_zone*/temp"
67000
72000
68000
75000

After: 
root@unifi:~# ssh root@172.27.1.242 -t "cat /sys/class/thermal/thermal_zone*/temp"
57000
60000
56000
62000

These values were obtained after 6 hours of streaming with 20 to 30 clients.

I really do think bringing the AP just off the ceiling / wall would help the thermal performance a lot. Well done on a DIY version of this.

I also really like what you have done. Good work.

Nice work. You could just use Spacers behind the bracket too, if there is enough gap between wall and unit say 1/4" that should help with air flow.

Yes, in any case, the distance to the wall brings something even without the additional cooling surface. However, Alta-MattH has assured, critical temperatures are not reached. Not even under a ceiling. The low temperature is just more reassuring.

think alta should have alternative mounting options avalible for purchase
