My fan runs at over 3000 rpm on after a cold startup.
I have reset the SMC, it doesn’t help
I have run diagnostic mode, no errors.
Have even reduced all my processes and removed chrome.
This is a standard Mac (Retina 5K, 27-inch, Late 2014). Never been opened or updated. I doesn’t sit in the sun and is in a cool place.
It is currently running at 3200 RPM with very normal temperatures. CPU 85 C & GPU 67 C
I have no idea what is, is it the actual fan? Is a just clogged up? Is the fan sensor bad?
Want to repair, but don’t know what the problem is.
