Are rubber fan mounts worth it?



I have a CM megaflow 200mm and some stock CM fans

 
Rubber is good for reducing vibration to the case and thus the noise.

So if you care about noise, sure it's worth it. A long with a good fan like

Use the rubber mounts then, that will help better then having to buy new fans. They will work for what you need them for.
