Hello, I just bought a refurbished 6-core 15" 2018 and it is running extremely hot (150-162 degrees). Indexing is done, the system has settled down, but the machine is much hotter than my 2017 sitting next to me. The GPUs are more or less the same. And, the 2017 is loaded with 40 tabs in safari + emails + powerpoint, while the 2018 is only running 5 simple safari tabs. When I connect 4K external monitors to each of them, the difference is even bigger. The numbers are below: 160 degrees vs 126 degrees. I am really upset. Do you think it's because (1) I bought a refurbished one or (2) because it's 6-core or (3) it's supposed to be like this?
