That would depend on the construction... if one were to use a quiet motor at a relatively low speed and streamlined parts, it probably wouldn't be too noisy. If it's just a square bar spinning at 3600RPM, of course, it will be much noisier. I'm thinking about one for my office -- well, my cubicle. I'm thinking about a dual-purpose device... if I build the clock/display using a fairly good sized prop for an R/C airplane, I can have it serve as a fan as well to keep air moving. Will have to spin up a couple and see if that makes a lot of noise. On the other hand, in a cubicle a little white or sort-of-white noise might not be a bad hing, I hear it cuts down on distractions from outside noises. I get a lot of conversation and keyboard sound from adjacent cubes, maybe I *should* build a slightly noisy clock!
