How (and why) to Ramble on your goat sideways
I remember when I started fooling around with LEDs as a hobby around 15 years ago. Among the two major benefits were that they used far less energy and they ran significantly cooler than incandescent bulbs. I was befuddled the first time that I ever heard that LEDs were running into heat problems, probably 2-3 years later.

Precisely.
LEDs are highly power-efficient as compared to restive filaments, but they're still semiconductors. As such, they have a fixed forward voltage, and generate an amount of heat which is more or less linearly proportional to the current flowing through them.
And semiconductors, unlike resistors, don't deal with heat very well.
Lasers, particularly solid-state lasers, aren't the most efficient devices in the known universe, but they're significantly better than LEDs in this regard.

Another Florida Man incident
Florida man kills couple, tries to bite man?s face off - NY Daily News
He was still atop and biting the victim when police arrived. Both tasing and police-dog bites failed to get him off.

Ok, so my old 2007 vintage draft N wireless router finally died and I need to find a replacement. Someone convince me not to buy an ASUS RT-AC1900P
https://www.asus.com/us/Networking/RT-AC1900P/
I mostly picked this because it'll do N and AC so I have a little future proofing, plus my local BestBuy has it in stock so I can go pick it up tomorrow.
Right now I'm temporally rocking a WRT54GL that I pulled out of retirement and it can't seem to keep up with my wireless bandwidth hungry lyfestyle. I can make Netflix through my Chromecast kick into low res mode if I do too many things on my phone while connected to the weefee. No bueno :(

The Linksys firmware is akin to Windows 3.1 on a fully built Core i7 rig.

Linksys SUCK. I had an older router, which "required" me to upgrade the firmware. Halfway through, it just stopped. Essentially, the upgrade bricked the unit. When I contacted the company, they claimed it was a known issue, but would do nothing to help fix it.
I will never own one of their products ever again after that.
The Asus worked right out of the box. The only thing I had to do was set the password. It has never had to be rebooted in about two years, unlike the Linksys, which needed a reboot about every two weeks.

I will say that I think ASUS routers tend to run hot. When my RT-N66U failed I disassembled it and found evidence of overheating (seriously discolored traces, the main heatsink was bowed not making full contact across the two chips it covered, etc.).
For my RT-AC68R, I bought a cheap multi-speed USB 5v computer fan, plugged it into a USB phone charger, and propped the fan behind the router. Made a huge difference in the CPU and radio temps.
Discoloration on the RT-N66U from poor cooling:
