yeah, thats what I thought. sticking out of a computer/laptop, the fan site horizontal(flat), but attached to a hub, you have many orientations, depending on the hub. I'll put my hub on its side when I get my new batch of moonlanders.
Would the fans on these fair better if they were oriented differently?
It is a sleeve bearing right? I'm thinking it might be better if the usb hub sat on it side, so the fans could lay flat.
I run mine flat, not vertically but I have direct replacement ball bearing fans coming.
Sleeve bearings run better horizontal, if your run them vertically the perpendicular forces against the shaft will start wearing the sleeve bearing faster than normal and it will start vibrating more. Ive run these fans vertical and so far most of them are holding up fine after months of use.
