nope, these machines are not "normal". Compaq/HP has a bunch of machines in this series with this kind of problem -- you WILL run a supported OS on 'em, or love the sound of jet turbines. I've got some DL380 G2s that default to full-speed on the fans, instead of cranking up when they get hot. Starting slow and speeding up when needed is a very tiny improvement over what mine do. Lack of documentation and reverse engineering effort has kept this from being fixed in OpenBSD, as far as I am aware. other OSs usually just rely on the HP provided binaries (as long as HP choses to provide them...).
