Look for a Thermal menu under the Power main menu.
They will not run too hot, so that they allow damage to themselves. Run them as hot as you want, until they start self-throttling.
You will see that from time to time depending on the project and usually only under the passively cooled cpu...though you're running an HP and it may have a different cooling solution. As Z said, until you see throttling or errors, don't worry about it. The processors will shut down prior to damage. So, how are you liking the 24 threads so far? I love mine.
Personally, I'm not a Win 10 fan, but I'm old and crotchety. The only computer I run it on is my laptop and only because I lost the ability to access all my music when I reverted back the Win 7.
I love the box. Can't wait to crank it up on a real challenge. I was on PG but I'm on WCG now. Let's see what this can do. I want to upgrade a few badges over there.
