Query: Noisy but compact

This fan is okay for a small space, but the fan blades chop air so loudly that it's not very practical for an office or for use in close proximity to the user who needs to hear what's going on around them. It moves some air, but it's highly diffused - not focused well. Not what I'm looking for in an office/desk fan. Good for 'white noise', like one reviewer mentioned, though it's not true white noise. It mostly sounds like a Cessna flying overheard.
