Hi, I have a Mac 27 Inch 2015 3.2G I5 Core Model. So This is my second one and here is what happened. My First MAC same model I bought Late 2015. The fan would randomly turn on full speed at start up. My computer has not been on in 24-48 Hours so Heat should not be an issue and its 68 degrees in the house. I had hard shutdown and it goes away. Call Apple Care, they have me reset the VRAM I think what they called it and should fix it. Nope no fix. It starts to do it again so I call them up again. They reset same stuff and have me unplug power ETC. Week later does it again. Take it to Apple and they fix it for a few days and replace the fan. Get it all the way home and the Display won't start. Take it back and they fix the display. Then 2 days later Fan comes on again full speed at start up. Take it back to Apple and they tell me they have never seen the issue and give me a new Mac. So here I am 3 months later and it's doing it again. Full speed at start up and it won't stop unless I do hard reset. Call up Apple and they have me do the same VRAM settings. Week later it does it again. So now I need to make an App with Apple and really get tired of hauling this thing into the store.
Does anybody know if this is a known issue? All I do is browse the Web and Watch iTunes so not sure what's causing it? This is the second MAC that has done this and Apple Care says they never have heard of the Problem. Any ideas?
iMac (Retina 5K, 27-inch, Late 2015), OS X El Capitan (10.11.6)
