Run Apple Diagnostics. List the detected errors.

Thanks so much Mon2.I will check the link and I wonder if you have the board view of this Mac M1? I have try to find one on the forum but don't work on my PD board view..I believe is for windows and I use Mac.Thanks Again

I did run the Apple diagnostics and tells me that there is a issue with the fan.I need to mention that the water did touch the usb-c connector and I did replace turns on without any issues but the fan is my main problem.

I did replace this cap and the 621371 component.When I did remove the component the oxidation did take a one side of the trace and did scrape and work the points and use another component from a donor...but still rapid fan spin.I did try another flex cable, trackpad and same result.The Mac like I mention powers and works normal but the fans running like crazy,

Share a pic of the fan connector that is driving this fan. If there is a mating issue, the fan will be in hyper mode. If there is a fan sensing issue on the speed feedback, the fan will be in put into hyper mode.

Can you run the Mac app that can control the fan speed to confirm this is possible with your fan? It is a freeware tool that I know we use at our shop.

Can you please let me know the App that you use on the shop.I did install ssd fan control and no changes on the speed issue.

I believe it is this one but can confirm in the next day or so. You can test the free version.
