15% load can mean a single i9 core boosting to 4.8-5ghz. The OP is correct. When I use a single threaded program that is keeping a core pinned at 100% why would it be unreasonable for the fan to be on?
I dont care if the fan is on. I care that the fan is egregiously on. It is probably 95-100db on. That means that the macbook is fundamentally unable to manage the heat load it generates. It would be one thing if I were in the middle of the desert outside at 100degreeF conditions. But I was indoors and the ambient temperature was probably 68F. Again, I dont care if the fan runs, I just dont want to hear it, and I dont want the fan to be loud enough that everyone worries that my laptop is going to "catch fire", "Take off", "heat the room", and a half dozen other comments that were made at a client site. I bought a macbook to have nice hardware that I dont have to worry about...
