I recently upgraded to fiber internet and I'm now getting ~8gbps down. I've only got 2 thunderbolt ports on my PC, so I was looking for an adapter from ethernet (rj45 connector) to usb-c. So far I've found this:

Am I being silly? Wouldn't such a small adapter get insanely hot? Should I just use a much cheaper adapter rated for 5gbps instead? I've read that the real-world performance of those generally only cap out at ~3.6gbps, so it feels kinda like a waste to not get as much speed as I can out of this internet.
