Ok im looking for a good Horizontal fan....I know not to use Sleeve due to fact the bearing is not set up for that position..so what type bearing should I use in that position(will be my top Fan) ??
If you mean a horizontally mounted computer fan, then there's Hydrodynamic and ball bearing, and that's about it. Sleeve fans in general don't like being mounted that way, and my experience with an Enermax Marathon Enlobal Magnetic Bearing fan left with the opinion that I'd rather have a sleeve bearing. Not that I don't think maglev type bearings don't have great potential, but that particular one was just no good.
