Are these the type of bearings that if i put psu sideways in like a lian li case will wear out rapidly ? that are bassicly a side grade of the crappy sleeve bearing fans ?
Already have hydraulic bearing fans from Alphacool and already have terrible experience with those i dunno if hydraulic dynamic is any different then hydraulic fans.

Greatest life. Can be mounted in any orientation.
 
If it dies early, it is likely a manufacturing/cost cutting reason, not an issue with the type of bearing in general.

I think you confusing fluid dynamic fans with hydraulic dynamic fans unless evga is not being clear in which case i would like confirmation from evga

I did which is why i am confused it mentions no hydraulic anywhere let alone hydraulic dynamic only hydro dynamic which not even the same.

Do my alphacool fans aren ot sleeve bearing either can be placed horizontal as well as vertical but just do not have the increased life span
While hydro dynamic have increased lifespan and last longer ? if so how many hours contineusly till failure ? since fluid dynamic fans can last from 100,000 to 300,000 for example does evga have any psu's with these type of bearings in their fans ?

Almost every fan manufacturer has their own label for FDB (Fluid Dynamic Bearing) fans. Noctua calls their own SSO and SSO2, but it's still a fluid bearing at its core. FDB bearings are the best for longevity, sleeves are the worst. Ball bearings are in the middle, but tend to be the loudest of the three. I have 13 year old Noctua FDB fans in my case, run 24/7 and still quiet as ever.
