Kind of depends on the steady state and your target turbo frequency. I have my fans basically idle when temperatures permit it, but aggressively ramp them to full speed to keep the CPU as cool as possible so as to allow the frequency to scale up beyond spec. This results in a similar effect as a laptop fan -- under heavy load, the machine is loud. I don't really have a problem with this, at idle my computer is using ~100W, at full load, it's nearly 1000W. That's a lot of heat to get rid of, and it has to go somewhere. Having a large water cooling loop can help with the noise, but since I really only use the CPU that heavily for bursts that measure in the minutes at worse, I think it's fine.
It doesn't make me anxious but I do kind of like the feedback that things are under load. (I have the ramp-up time set pretty long, so something like "go build" that only uses all 32 CPUs for a second doesn't really trigger anything. There's enough inertia to prevent that from raising temps much.)
