The question says it all; I'm using a 2018 MBP 15", i9 processor, 32GB of RAM and 1TB storage, running macOS Mojave v10.14.2. Does this look normal? On the first picture I'm using Chrome to stream a 4k video. On the second photo I have a virtual machine (VirtualBox) running (Linux). When I had the VM running, the fans were on blast - loud enough for me and anyone around me to notice.

  • A lot of the differences in how different applications utilize resources on a computer is how the program is written. How efficiently the code works, how optimized it is for the task at hand. You are not comparing anything that is comparable (Apples and oranges, as they say). If you want to compare something try VMWare, Parallels and Virtualbox and see how they they operate with an identical VM. Or different browsers with the same content. – Steve Chambers Jan 10 at 0:16
  • What I’m asking is whether these are normal when running a vm, or when watching a 4k video. Not whether watching a 4k video and running a vm are comparable. – Later_72 Jan 10 at 0:18
  • "normal" is exceptionally variable and there are so many variables that comparisons will be nearly meaningless. But maybe someone out there will know more than me (likely!) on this subject, which is why this is a comment and not an "Answer." – Steve Chambers Jan 10 at 1:39
  • Yes, I agree, but heating and fan noise is common in the new MBP 15" so these tasks are common and I'm wondering if the stats are normal. – Later_72 Jan 10 at 1:40
  • Normal in relation to what? The graphs you supplied show what your Mac did in a certain time frame (within its operational parameters), however, you didn’t supply anything of which to compare it to. – Allan Jan 10 at 11:27

Depends on what you mean by normal:

Do you mean "is my laptop broken", then the answer is no.

If you mean "can I achieve the same functionality without having fan noise", then the answer is most probably no. For example VMware usually requires much fewer resources than VirtualBox. You might also simply have a configuration issue with VirtualBox, or lack installing the VBoxDrv package within the guest virtual machine to get better performance.
