Re: iMac fans starting to get hot and very noisy again!
Juat to be 100000% clear, no one here can say what is wrong in your computer setup as all we can do is guess. Asking Jack to say that it is your graphic card isn't fair as he can't be sure either without beeing there and doing tests.
The best advice is Jack telling you to go in getting that iMac to a Mac certified help support and let them figure it out for you before starting to buy a lot of new stuff.

Re: iMac fans starting to get hot and very noisy again!
My gut feel is its likely not "just the graphics card", I would more expect a combination of stuff, maybe a faulty fan, corrupt PMC, poor airflow, bad thermal paste, faulty temp sensor, etc.
And there are lots of resources (but they are a bit scattered) on the Web that cover troubleshooting fan issues. From checking the vent air flow, resetting the PMC etc., checking for faulty fans, etc. all those things you should try yourself. https://www.cnet.com/how-to/how-to-d...ud-macbook-fan (but many others as well). I've had multiple issues with MacBook Pros that were due to lint/dust ingestion, one of two fans failing, or corrupted SMC. I've also had older iMacs such a huge amount of dust into them. Some of this could be as simple as your iMac switching to the "high performance" GPU and that then triggering issues in combination with other things when running Pro Tools or other select apps, and that flipping the system into higher fan speeds. You can watch in the Activity Monitor GPU screens and see what GPU is being used. Or there is another utility, not sure if it still works on latest macOS. |
