corsair af120 led quiet edition mounting?

[hitlergoesgaming]

so basically I bought a dual pack of corsair af120 blue led quiet edition and I noticed that it uses sleeve as a bearing and i'm just wondering if its okay to mount them horizontally at the top of my case as exhaust? stated that the bearing they used are sleeve

oh and I searched their product online http://www.corsair.com/en/air-series-af120-led-blue-quiet-edition-high-airflow-120mm-fan it says that it is ideal for mounting at the rear and at the top of your case as exhaust, but I'm not quite sure if a sleeve bearing would make up for it
