Noctua Fan Placement

Hi, looking at replacing a noisy horizontally mounted case fan at the bottom of my case - does anyone know if the noctua nf r8 80mm fan can be placed horizontally?

I've currently got a Sharkoon Silent eagle fan there, but its bearing doesn't like being horizontal and so makes a loud rubbing noise. So I'm looking at putting a Noctua there and moving the Sharkoon somewhere else. My case only has mountings for 80mm fans, hence the reason for not gettting a larger fan.

Thanks heaps
