Late 2016 MBP fans on constantly

[AthenaNoctua]

I'm typing this on my father's late 2016 MBP (top spec 15"), running Sierra 12.5. I have Safari, Mail, Preview, Activity Monitor and Notes running - that's it. The fans are so loud they sound like a cooker extractor hood, and the area beneath the screen is extremely warm to say the least. This machine was an upgrade to his old mid-2012 MBP, which was base spec and I don't recall the fans running like this - ever.

Secondly (and this may-or-may-not be related), I have a problem with windows turning to red rectangles (see screenshot) which gradually reappear when the cursor is moved over them, making me wonder if this is a refresh issue.

Now it's always left to me to deal with AppleCare, despite this being my father's machine, and despite the fact he knows damned well I can't cope with using the phone (I'm autistic), he always pleads ignorance (it's wilful - I've been trying to train him for decades, and he refuses to learn), but there's no way I can deal with a long protracted call to Apple (if it's deemed necessary) so - somehow! - I need to make him understand (it's his computer, FFS - WTF should I have to deal with it...?!).

So what gives - and is calling Apple necessary?

Peace

Well, it kind of looks that the laptop is broken. I'd bring it to a shop so that they can look at it.

Open Activity Monitor too see what applications or processes are using so much system resources. Under the CPU tab, you can click on % CPU to sort the processes in order of CPU usage to see what's using the most. And you can do the same under the Energy tab.

Do an SMC reset for good measure:

1. Shut down your Mac.
2. Unplug the MagSafe or USB-C power adapter from your computer.
3. Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds.
   If you have a 2016 MacBook Pro with Touch ID, the Touch ID button is also the power button.
4. Release all keys.
5. Reconnect the power adapter.
6. Press the power button again to turn on your Mac.

And, don't worry about talking on the phone - you can do an online chat if you would prefer.
