I have 3 more of these fans are now several weeks, two are already almost a year.
One of those that you have installed a year ago, will vibrate from the beginning.
I have installed a few weeks ago still 3 more of these fans, in the hope that the defective fan was an exception.
If you let them just run on their standarttdrehzahl they cause any problems, but since I got this fan installed PC in a high-end gaming, the speed changes frequently ziehmlich from 1000-1500rpm.
Now I'm pissed off now and I regret buying this fan! All rattle, vibrate or hum without reason and now even on standard speed!
Since the supplied rubber holder may not help !.
If you another 12cm fan with blue Lighting knows what are good, I am happy if you give me telling this !.
Thanks
