Thank u very mutch for the reply.

I'll try all the checks you suggest to me !!
My Zbox is a C model .... so there is NO fan ... only passive cooling

I'm thinking to change my HTPC ... and I like to buy a new NUC 6i3 skylake
Do u think is a good choice and I'll can solve my problem ?

And about cooling, I could choose to:
passive cooling ... zbox CI523
Active cooling ... intel nuc6i3syh
