I couldn't find any technical answers to this question so I hope you folks can help. I have 2 monitors (Sony 49" 4k via thunderbolt and a 27" HP via HDMI) plugged into a MM 2018 i7 6 Core, 32 GB ram. I run music production software. When running intense and pretty large Pro Tools music sessions, the Mac's temps easily run between 80° & 98° Celsius. Yes, quite high but not throttling. I'm very concerned about the Mac's "long term" high temps and I was wondering if I got a 580 card and eGPU enclosure, would this bring the temps down on the MM and by how much? At this point I would think the internal 630 card is probably working hard, bringing the temps up. I could be wrong... A positive would be a better card would also give me better graphics results. Thanks.
