2017 MBP Overheating

The first thing I would try, assuming you have not inflicted upon yourself the dreckware that Grant has mentioned, is a System Management Controller (SMC) reset:

using the instruction set for Macs with Intel processors. The SMC manages a lot of stuff including the cooling system and its sensors.

If the problem persists, I would then run Apple Diagnostics. The resulting codes can point to, among other things, fan and temp sensor issue.

What browser do you use? Are you leaving it open in the background while you use CC? CC apps are fairly high up the list of stressors, and a greedy browser left open could increase internal temps.

If you want a data-driven evaluation in this setting where we can neither see nor touch your computer, please post an EtreCheck report. We can quickly and within the limitations of these forums help you determine what issues are at play without our playing a protracted game of "20 Questions" with you that could go on for days. 

EtreCheck Pro is available here:

The free version will do nicely for this purpose, although the app is worthy of our financial support.

We can see hard data about drive performance, software issues and interferences, and RAM usage. Etrecheck is the development of a long-serving and trusted ASC contributor. It is a reporting app, not a "fix-it” app, expressly for displaying information in these forums to help us help you remotely. It will not reveal any personal or secure information.

How to use the Add Text Feature When Post… - Apple Community

By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners. or a VPN that you installed yourself. The main reason is that they are relentless in scanning your files, non-stop, looking for virus-like patterns in Everything. When completed, they do it all again.

The idea that a third party, with no special knowledge of the inner workings of MacOS, can somehow find a simple way to protect your computer — that is not already being done by MacOS itself — suggests that the MacOS developers are somehow "holding out on you". That is absurd.

You should remove any and all (other than Apple built-in) virus scanners, speeder uppers, optimizers, cleaners, App deleters or VPN packages you installed yourself, or anything of that ilk.

Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can ruin performance, but are not inherently dangerous.
