Yes. It’s not necessarily the size that makes the noise, but rather the rpm required of the smaller fans to move an equivalent amount of air. I have a fan in my phone, for instance. It is so small that it spins at 23,000 rpm to make just a small amount of air movement I can barely feel, but easily hear. My ceiling fan can’t be heard at all but still moves WAY more air while spinning at a couple hundred rpm. The air turbulence from blade speed is most of what you hear from a fan.
