Anyone lost a router to heat?

Hardware Questions and Recommendations

As most of the northern hemisphere is experincing extreme heat so are the routers. Among my pasively cooled devices an idle rpi3 is at 62°C the coolest. The wired router is at 76°C and my at the the hotest at 82°C.
I guess some of you already have similar experiences.
Were any of these fatal to your devices? If that is the case how hot were and for how long it survived?

Thanks

My rpi3b shows the following temperatures (raspberry plastic box, no heat sinks, room temperature is 26°C):

I already run my Asus router up to 92C without a fan and with fans, it drops to 58C, In normal Asian heat .pk domain.
Rpi runs at max 52C even in 40C+ weather. with Ice tower cooler.

Yes. This is my router. I made this video too.
Same can be done with other devices, especially during this heatwave when devices might require active cooling.
