What's the best way to attached the temperature controller's therometer on fermenter?

If your using a STC1000 taped to the side is fine, if your using a PID based BrewPi or something you should use a thermowell.

Because there is no prediction from the STC1000 your going to probably have quite a bit more overshoot if you have it in a thermowell i would think? But i guess that depends on the efficiency of your fermentation chamber, and if your using a freezer or a fridge. A freezer will obviously overshoot a lot more because they get so much colder.

The degree of overshoot with a thermowell depends on a number of factors:
- Temperature setting of the freezer/fridge's thermostat (i.e. how cold it gets when running).
- How much heat (and cold) the walls of the chamber hold
- The wattage of your heater
- The location of your heater
- Radial position of the thermowell in the fermenter
- The length of time the freezer is chilling for; i.e. the target temp drop needed for the beer.
- etc.

So you may get pretty big overshoot if, say, crash cooling from 80 to 50F with freezer set to max cold and with an undersized (like 10W-20W) heater stuck to the freezer walls.

But during normal operation with a 0.5F differential and a reasonably sized heater wrapped around the fermenter, you won't see much overshoot at all with a thermowell.

That's been my experience as well. Maybe a little overshoot (a degree or so) during the initial chilling down to fermentation temperatures, but after that it generally stays with 0.3° C of the set temperature.
