Graphics card roaring sound

[chrisgs]

Hello, i have an AMD radeon 260x OC edition 1GB video card.

2 days ago i changed to a new pc case because my old one was a bit bad (no cable management space,psu on the upper side etc).
Since that moment when my card's fan reaches 50% or more it makes an annoying roaring sound.Strange thing is that when i turn my case horizonal that sound doesn't exist at all but when my case is vertical the sound goes on and on and on

I made sure that the GPU connection to the case is good and that all the screws that are holding the GPU to the case are okay but it still continues to do this sound,i've seen a video in which a guy supports his video card from not moving by placing a stick from the psu to the GPU ( photo attached bellow),i tried his way of fixing the problem but it didn't work for me,the only thing that seems to work is either to low the GPU fan to low RPM's or turn the PC case horizonal,

Here is the screenshot of the guys's solution: http://prntscr.com/8mze1l

Here is a video of the problem of my GPU(sorry for the quality and pls imagine that the roaring sound is louder that the video's) :https://www.youtube.com/watch?v=GIknoQoJfVs

I'm looking forward to your help and thanks in advance!

Looks to me like the bearing has worn down on the GPU fan...

I think that's the reason too..i think my card's warranty is still valid so i'll just send it to fix it,i just wanted to identify the problem and see if it was sth i could solve alone,thanks for helping ^_^
