This. I got an HP Elitedesk g4 (i5-8500) a while ago, enticed by the small size but desktop-tier performance, and support for dual NVME + SATA drives. I figured it would be great for my needs as a transportable PC, instead of a laptop; it was much cheaper. Boy, do I hate it. It has this whiny fan noise than never stops. And if the CPU needs to do the least bit of work, the fan ramps up even more. Otherwise, it's a nice little computer. Also, the newer generations – I think starting with gen 6, which look different – seem quieter. They probably realized that having a fan rattle around isn't great.
