Test give me this error: 4SNS/1/C0000008: Th1H - - 124

To debug the error code you need this writeup: AHT error codes. So in your case 4SNS is a system sensor after the : mark T is temperature and the h is heat pipe (heat sink).

I would install a good temperature sensors & fan monitoring software to double check things. I like Temperature Gauge which you can download from the Apps store. There are others out there that are just as good. See what it tells you and let us know too.

I recommend backing up your system and after that you may want to open your system up to inspect it for dust and debris build up on the fans & heat sink fins as well as the logic board it self. If things look clean then the sensor most likely needs to be replaced. It's a bit of work here as you need to pull the logic board out to get to the heat sink and you should apply a fresh coat of thermal paste on the chips if you go this far. Review this IFIXIT guide Heat Sink Replacement

If you do see a lot of stuff you should get a can of can'ed air and a soft paint brush to lightly scrub the fan, fins & logic board and using the can'ed air blowing out the junk.

Did you install TG Pro (Temperature Gauge) what does it show? For less than $20 US it offers quite a lot of info to isolate the problem.

@roberttomsich - I’m sure both have! But until you properly diagnose the issue throwing spaghetti at the wall won’t help you! Did you install TG Pro? Which is the current version of Temperature Gauge, what does it tell you?

Give. The location of the sensor it can often encounter liquid spill events which corrode the device and/or solder joint connections. But again without doing the basics of diagnostics and inspection it’s just a guess.
