wAP ac heats up to 60 degrees Celsius in idle (and >70 under load) — is this OK?

So, I got myself a wAP ac. To make its 5 GHz radio cover the whole flat, I did not limit its tx power output and configured it to use the 5745 MHz channel (which is rated for 30 dBm here in Russia). The 2.4 GHz radio is turned off (my pre-existing RB2011 has a a more powerful transmitter) and the CPU usage is pretty low. I'm using the stock power supply unit and PoE injector; voltage meter says 26.5 V. Ambient temperature is ~25 degrees Celsius, i. e. well within the documented limits.
After 30-40 minutes of calm uptime (one client, no heavy loads) I noticed that `/system health print` says 61 degree Celsius. After 5 minutes of iperf3 it heated up to 70 degrees (and continues towards 80 as I'm writing this). Is that OK?
Update: so, in ~800 seconds of running iperf3 it heated up to 85 degrees Celsius and apparently stabilized at that temperature.

I've noticed this too on my wAP AC I've received today - but it idles at around 65-70 Celsius with no clients connected (ambient is probably closer to 30 here), using stock PSU and PoE injector too.
Hope it's within normal limits (had a quick look but couldn't find anywhere stating the operating temperatures, only tested ambient) but time will tell i guess

Same issue here - one unit idles at 60c, the other 62c. I noticed when configuring it that even without any wireless traffic it got warm to the touch. I haven't done any stress testing, casual web browsing seems fine but it's also the middle of winter, I wonder how warm they will get in the summer and if it will affect performance.

Yes, it is fine. The units run quite hot, but work fine even in ambient temperatures 65C+

OK, thanks for clarifying that.

It is absolutely normal. Because most electronic components rated at 85 degrees (some of electronic components rated at 105 degrees).

I bought two wAP ac, one of them die today and I notice that it run quiet hot
