is Hydraulic Bearing good for horizontal mounting?

[mackevicius]

I need to buy some case fans that could be mounted horizontally and i wanted to know if Hydraulic Bearing is any good for that?

I'm guessing fluid dynamic and then yep they can go any which direction you want.

Fluid bearing / Hydraulic bearing fans can be mounted horizontally, but sometimes you can get a slight noise when mounted horizontally. It's usually a faint clicking sound. I have a 140mm one mounted horizontally, and if it's the only one on, I can hear it, but under normal use I can't hear it at all. Usually if you read reviews, you'll find other complaints about this, but I think it's generally overblown.

When selecting a bearing type, the design engineer must consider the orientation for which the fan will be mounted. If the fan needs to be mounted vertically, the engineer might choose a sleeve bearing fan. However, if the fan is mounted in any orientation other than vertical, the engineer may want to select a ball bearing fan.

Due to its lubricant dependent construction, sleeve bearing fans should only be mounted and stored horizontally. Meaning it should always stand upright with the direction of the airflow parallel to the ground. If mounted improperly, its life will shorten and the noise level will also increase. On the other hand, Ball bearing can be mounted various positions without endangering its life span.

look at info on Ceramic bearings and then case fans with them
