You can buy the same gromets or whatever you call the silicone mounting devices that are used on the silenx fan. I did, and I can say, that they are definitely worth it IF you have a fan that creates a lot of vibration noise or a case that reverberates a lot. I have an aluminum lian li and when the adj enermax fans were at higher speeds there was an annoying buzzing from the top fan. You can ussually tell if its vibration buzz by pushing lightly on the fan casing or the case near the fan mounting. Don't block the fan flow. If the noise changes, then its probably vibration noise and those help. I am more impressed today with the enermax thermal control fans that I bought earlier. They are definitely better than the vantecs. It's funny, I initially attributed the whiny sound the vantecs were making to the enermax's. One of the nice things I've found about the enermax's is that if you interfere with the airflow on the intake, they don't get much louder or change in pitch much. The panaflo's are the sameway. The vantec stealths were hideous about that. So is the thermaltake silentcat that runs on my hsf. The panaflos that I ordered do not have an rpm sensor on them. Just a heads up to you guys, three pins do NOT equal a sensor on the panaflos. They are all built with a third lead, but they do not all do rpm reporting. Some only do seizure reporting. Most do neither.

Make sure its a model with designation BX if you want fan reporting. I am haggling with the net vendor that I bought my fans from for fixing the fact that he falsely advertised the panaflos that he sent me. I am now contemplating keeping the adda's that came with my lian li since I bought a fan controller. I am contemplating using the two enermax and two addas. I would be able to adjust all four, plus the enermaxs would auto adjust as temps change. I might even consider all four on a fan controller. For ball bearing fans they've impressed me. The adda's are sleaves. The vantecs may seem great compared to some really loud case fans, but I would never buy another set again. I am actually ooking to get rid of mine. Anyone interested in two two week old vantec stealth fans? =D
I haven't heard the medium speed hypro panaflos or addas. I really want to check them out..
