I’m booting openwrt off a usb c thumb drive connected to a fanless Celeron mini pc. The pc is cool but the thumb drive is so hot i can’t touch it.
Any ideas?

It’s normal. Some thumb drive heats a lot but it will continue to work.
I wouldn’t call it normal. It’s the norm because the market is flooded with crappy drives using JMicron chips. Buy something with a Realtek or Asmedia chip and it will work fine without getting hot.
How does one find out what chips are in what USB sticks? Manufacturers don’t make this information available. At best you just find read and write speeds, usually just the max possible read speed and nothing else.
It’s normal for it to heat up under load, but it’s not normal for it to be under load 24/7 indefinitely.
