Pros: Can be mounted upside-down without unwanted noises, great CFM/DB ratio
Cons: Would like sleeved cable
If you want proper quality fan and not sleeve bearing rubbish products, this is one you should look for.

A well-oiled non-grooved sleeve bearing won't make any noise either when spun at non-extreme speeds. Now if you compare a Kama Flow to a chinese offbrand $3 fan, yeah, it will make noises. My point was, your conclusion is wrongly phrased and can lead to people believing this is not a sleeve bearing fan. Take it as an advice, not as a criticism
