Well, I ordered a Mugen 5 Rev B cooler for the thing; should be here Friday. I got a chance to try some FarCry 5 on it this evening, and temps were in the low 80s during gaming...I can't send something like that out the door; I suspect his parents keep the house pretty warm during Texas summers. In for a penny, in for a pound I guess.
Regarding the settings, I'll go take a look right now.
