Temperature depends on tank construction, type of juice, amount of airflow, wattage, and a bunch of other stuff.
I don't use TC all the time, but I have used best-practices to avoid high temps. Those included adding DW to my max VG (I am PG sensitive) rotating setups, improving airflow, when chain-vaping rotating mods.
It's really almost impossible to tell how hot your coil is getting based on the "vape" temperature, but things can be done to reduce risk WHILE you are getting up and TC vaping.
Starting TC with drop in coils does have advantages and the Crown is reputed to be a great tank. You'll get a sense of how TC-works on the mod you are using. MOST but not all drop-in TC coils nowadays are SS, but titanium is still common in some. Just make sure you watch a video review or two for your device's TC and how to use it, it's just the easiest way to go in my opinion. Various mod-makers offer various levels of precision and customization culminating currently in the DNA mods, which are most precise. But plenty of non-DNA mods do TC fairly well.
Using an RTA or an RDA is also a good way to use TC. Finding something that would suit your needs will be step one. I'd suggest a single coil RTA to start, for ease of building and also so you don't have such a tiny area to build. You can buy premade coils but unless exotic, most folks wind up making their own. You can check out the rebuildable atomizer board her for some good resources, including how to build to a specific resistance using an online tool called steam-engine.org. You basically need, well, veteran builders say a screwdriver that you know the diameter of, I was happier to buy a coilmaster kit which comes with a coil-wrapping jig and most tools that you'll need, although they aren't the highest quality tools, they tend to suffice. You will also get an ohms reader which you can screw your deck onto and measure the resistance of your coil by test firing it. You can do that on your mod, as well, if you don't want to invest in a lot of tools, but I find the ohm's reader a nice, stable deck I can pretty much assemble my tank onto including fill with juice, and test fire before I place it on my expensive, tippy mod. I've pretty much done everything terrible you can do to the ohm's reader besides catch it on fire, including leaking all over it and etc., but then I'm out $12 not an expensive mod.
If you want to explore the TC thing, you can, if you want to get into building your own coils, you will save on coil costs AND get a very different (to me good) quality vape. RTAs take some time and learning but they are ultimately worth it and for the cost of a few spools of wire (and in my opinion the best wicking is rayon ) so a box of Rayon, you can be self-sufficient for years and if you choose stainless steel SL16 I think is the standard, wire, well, you can vape in wattage or TC mode. It's a fun process but give yourself some time if you undertake it, research what you think might appeal to you, and try to have fun along the way.
Good luck,
