I have a 2019 Mac Mini i5 with 16 GB RAM and 6 core i5 with 2 LG Ultrafine 4k displays and when using Microsoft Teams will hear the fan spin up, in most cases 20 - 30 minutes into my meeting. I am a complete novice when it comes to graphics cards but was wondering if the Blackmagic eGPU would help prevent that from happening. I am not a gamer and use no (other?) graphics intensive software. Obviously they aren't available through Apple at this time so I would have to get one from eBay but it's a lot of money to shell out if it won't make much, if any, difference. Thanks!
