Mac Pro shut downed by itself.

Does anyone know why my Mac Pro 2010 shut downed by itself when I was playing Starcraft 2 or editing on Photoshop? I notice that the 2nd CPU is very hot and I assume that the heat cause this issue but not sure.

Have you cleaned out the Dust in your Mac tower?

Dusts shouldn't be a problem since I always clean it.

Sounds like an overheating issue, maybe check your fans?

I used Macs fan control app to cool down CPUs but still, my Mac Pro shut downed by itself without any reasons. Again. I checked CPUs after that happen and it was cool not hot. I have no idea what else to do.

First run an Apple Hardware Test. Some Mac Pros have been known to have poor records on over heating processors.

It doesn't work since RX 480 does not show booting screen.

Then find a tech in your town to look at it. Maybe the compound has burned off the processor or a fan failed.
