How bad is the vibrations? It may cause other issues if the vibrations get too bad.
I was asked to look at a system that was excessively loud. Had some blades missing from the cpu fan.
They I was told they had knocked the system over in the past.
Yeah, guess that may do it.
If it is not overheating or vibrating like bastard, it should last for a bit.
You may be able to zip tie a fan to the cards heatsink to keep it going for a while/permanently s well.
