I've got a 905p U.2 in an isolated storage compartment (Alienware Area 51 Case). Intel recommends "Airflow across the drive to provide cooling, such as a front fan and rear fan", but do you think it's really necessary in an isolated compartment? I mean do these things need cooling even without any extra heat sources?
I found this: "the upper operating temperature range has been expanded from 70c to 85c"
