Considering what most of us spend on assorted brew gear, plopping down $25-30 to build an STC-1000 outlet box and another $50-75 for a used fridge to gain precise temp control is a no-brainer to me.

On the question of probe placement, there have been some folks on HBT who ran side-by-side readings using one probe taped to the side of the bucket/insulated and a second probe inside a thermowell in the middle of the liquid. The biggest recorded difference (when there was one) was an insignificant +1 degree F at the thermowell probe. I get very stable readings with the probe taped and insulated, so I find that to be quite satisfactory.

Also i would like to document my own findings but i believe that i had read a math equation that shown that a rather big OG 5G brew could only increase around 7*F under fermentation... Like i said I am really wanting to do this but i jsut really doubt my beer is going to be better by an order of magnitude like what is expressed all over now days. Keep in mind...I have it at a nice temp.
My friend and I started fermenting in his basement. His basement is a nice stable 62°. We started out with carboys without thermometer stickers on them and we were making decent beers, but we'd get off-flavors. So we bought some thermometer stickers and he found out that our beers were getting into the 70's. So we switched to a chest freezer and a temp controller, and then we taped the probe to the carboys. Beer stayed at a nice 65° or so. No more off-flavors.

You may doubt that your beer is going to get better, but I don't.

Well. Theres a difference between having a stable temperature, and having control of the temperature.

Being able to raise/lower temperature is absolutely not cruical, but it helps. Lets say you're making a beer and need to raise the temperature after initial fermentation, or just want a higher/lower temperature than your ambient temperature the room/garage/basement, how would you do that without turning on/off heaters/ACs? If you have a fridge it's easy to set a STC to 2C and cold crash in the same place as you've fermented it.

I use fridges with heating belts and STCs wired into them. Since this is a hobby I spend a good deal of time on the fridges were great investments (cheap/free) since I can now focus on other things in my brewery and I know I can trust the fermentation is going according to my plan. Gives more consistency and it's one factor less to think about if you're trying to replicate a beer or do some changes to it.

Single best argument for temp control.

The temp difference between just a liquid and the rest of the room is going to be different because they will always be exchanging heat to attempt to reach balance.

In the case of your brews there's an active reaction going on inside which generates energy as a by product because nothing is 100% efficient. Energy comes out in the form of heat, and several other forms that don't have any impact here.

I don't believe temp control will make a bad beer better, but like others have mentioned, if you want to fine tune your process and have a better result, controlling this stage will improve the process of what's happening during the fermentation.

To put it this way. You can nail all the temperatures and volumes and what not during the brewing process, if you botch the fermentation all that work is wasted.

You can make mistakes in the brewing process, but nailing the fermentation will still make good beer, even if it wasn't intended to end up that way because of mishaps in the brewing process.

Let’s not forget that you also want to prevent temperature swings. I know my basement, at least, the temperature will fluctuate a good 5-10° between daytime and nighttime temperatures. Doesn’t seem like much, but yeast will behave better at a stable temps. Fact is you will produce better beer that has fermented at exactly 65° for 24 hours than beer that has gone from 65° to 70° back down to 65° over a similar time period.

Also I do not use a thermowell, I tape the probe to the side of the carboy and tape an insulating layer over the probe. When I first started temp controlling my fermentations, I measured the temp of my wort while actively fermenting over several batches with my Thermapen and it measured exactly the temp displayed by my Temp Controller. IMO a thermowell is not needed to accurately measure wort temps.
