2012 Mac Mini fan

In addition to the above:

I have now uninstalled Macs Fan Control and installed a paid for version of TG Pro. It reports that the fan might be broken or unplugged. It is not unplugged.

I have tried rebooting to Diagnostics mode but I get the "Cannot Load EFI/Drivers" error message

I am investigating the purchase of this:

Any further advice or suggestions would be welcome.

Hi den.thed

Thanks very much for taking the time to reply. Apologies for taking so long to acknowledge your suggestion.

I have tried running Apple Hardware test but irrespective of whether I reboot holding D or option-D I get an error message saying "Cannot load EFI/Drivers/TestSupport.efi"

At the moment I'm keeping my Mac cool using a room fan - a solution which works but is a little noisy. I have ordered a Speed-Design cooler but I am waiting for it to arrive.

My plan is to migrate everything important to a spare machine and to re-install the original operating system (if I can) and see if that makes a difference to my ability to run AHT. I'd be grateful of any opinions on that plan.

Thanks also for your suggestion to move to a newer Mac. It may well come to that but I would like to persevere with my 2012 for a little while longer if I can.

Thanks again

Mitch

My Speed-Design external cooler arrived yesterday and, so far I'm very impressed. Before it's arrival I was keeping my Mac cool by standing in on it's edge with it's base plate removed and directing a room fan into it. That kept it cool - just. The Speed Design device keeps the temperature much lower, and, while it's significantly noisier than the internal fan (when it worked) it is much less noisy than my cobbled together temporary solution.

Long term I suspect it might be time to replace the Mac.

Thanks for your earlier help & advice.

I saw a thread detailing how to reinstate the hardware test, but it seemed to be a lot of effort to just be told "yes, it's faulty"
