Should be pretty simple and not look bad at all.
The vents I've seen wouldn't work: The hole doesn't go all the way through, and if I pop the entire vent part out, I might as well just start with a G1/4 male/female extender. A simple G1/4 plug with a hole drilled in it might be better...
I think I might be able to fit it in a currently plugged inlet near the bottom of my reservoir. If not, I can always put it in from the top. Either way, what I'm currently thinking is that I'll get one of the plastic G1/4 plugs I have laying around and drill a 1/4" hole in it. That should be very close to 6mm. Then seal the sensor in with one of the epoxy products suggested in this thread. (I don't trust silicone as an adhesive.)
Instead of a plug, I could also use a G1/4 male/male adapter or a male/female extender, but then there would be a much bigger hole I'd have to fill and seal.

There's a story there... (TL;DR version is the last line of the message)
My last motherboard didn't support addressable LEDs, so I grabbed a teensy board (an overpowered arduino type project board) and programmed it to drive my LED's using whatever pattern I want. I also wired a few buttons to my case to allow easy changes. I had always wanted to get one of the little TFT or OLED screens and wire that up, and then write a service to pull temp sensor data from hwinfo and forward to the teensy board - and then display that data on the little screen. (I have a PERFECT place in my case for the screen..) I never got around to doing all that, however.
When I got my current m/b, I found that asus now supports addressable LED's. I also found out that Asus still hasn't learned to develop software, so their "aura" software sucks. Armoury Crate is even worse. So, I went back to the teensy...
Today, I'm doing the LED's with an ESP32 based board instead, and now I have the little TFT display as well. However, I decided that I don't want to depend on hwinfo64 running, or even my machine being booted into an OS for the display to contain information. As well, I'd like the LED's to change patterns, colors or whatever based on sensor data. (For example, if the water temp gets to 35C, the lighting should transition to red. If the delta between ambient air and water is greater or equal to 10C, it should start flashing and going nuts to get my attention.
I started doing all that with a 10K NTC thermistor, but those things suck, aren't calibrated, and the ESP32 has a horrible ADC. This is what the DS18B20 is for. (3 DS18B20's, actually. Ambient air, water, and case air.)
TL;DR version: I'm recreating some of the functionality of an aquaero, but I'm doing it my way, with my cosmetics, and whatever functionality I want.
