yes because your mac pro is made to sit under the desk, the current mac pro is sitting on the desk. The current 1070 or 1080 make a lot of noise if you have an eGPu on the desk..we will see, i hope apple is working hard with amd to make an capable easy and silent modular mac proI have seen a review where the reviewer run some renders for an extended period of time and complained about the noise. Just count the watts dissipated and it's clear it cannot work without a lot of air going through, or a lot of throttling.
What I have is 2 of the 5,1 Mac Pros and I don't even notice whether it runs at 2% or 100%, for arbitrarily long periods of time. And that's how it should be.
