Could you elaborate. Its basic physics.Everything you wrote is wrong.

Its not going to eliminate anything once the DSP has heated the air inside the case up, or the rack poweramp under the unit. Moving hot air over a DSP is not going to cool it, that works on food/humans as there is liquid/vapor around that surrounds and insulates the food/human body, blowing it away (even with hot air) is going to cool down food/ a human body, for CPUs/DSPs that's not going to work as there is no vapor/liquid around.
But simply circulating air inside a case is somewhat new
Yes, but there are aspects of basic physics that you’re not considering.Could you elaborate. Its basic physics.
I had some acoustical batting I had used on some speaker cabinets I had designed and some double-sided tape.How did you pad the top?
Thanks,

Side note: Actually a music studio I frequented used to use maxi-pads to dampen drums back in the day, and that would work too. Hey, it’s that time of the month for my axe!
Even a simple piece of black felt stuck to the cover on the inside will absorb reflections bouncing off the bare metal. Good luck!Thanks!
...Next time I'm in the mood to remove the 426 tiny screws that hold it down, I might try gluing on some foamcore, or maybe just replacing the cover with it.

and I guarantee nobody will hear it at a gig.

After installing the Noctua on the silicone supports I found the cover resonance was worse. Since Cliff suggested that the fan might not even be necessary, and since mine is used in an AC environment only, I installed the higher-resistance jumper to slow it way down. Helped a great deal, but there's still an audible cover noise, even with thick tape all around the cover mounting flange.

To be honest, I'm happy with the thickness of the cover. Not everyone will rack-mount it, and those who don't will inevitably stack stuff on it. Sure it adds a few ounces, but Fractal gear is designed to handle the rigors of the road and the bedroom studio.The cover is exceptionally thick. I'm not sure if the reason was to allow consumers to lay components on top, but to me it's an unnecessary over design that adds significant weight. ...Especially since it's designed as rack mounted. A much thinner plate with rolled grooves could have been installed saving weight and reducing other concerns. The rack handles are sort of useless too (to me), it's added unnecessary cost and weight.

Don't like the handles? Take 'em off. Depending on the size, mobility and design of your rack, they can make the job of racking the gear much easier. They're standard issue on rack gear of significant weight and/or height.
Exactly.15lbs is rather light.
So after all the main noise problem is not because of the air flow but more a problem of vibrations. They could get reduced when a cooler would have a quiter ball bearing? Is the Noctua NF-A8 FLX also optimized in that regard (in comparison to the original cooler) or is it about lower air noises only? Are there products that are known to emit less vibrations?
EDIT:
Ok, it's all in the thread. The noctua should do the trick.
I wonder if I could use small cable ties to fix it instead of screws. Cable ties should hold it save in place as well with less pressure on the mounting plate.
For me it was both; I dampened the plate where the fan is mounted, lowered the RPM of the fan, and dampened the top cover. The fan is mounted to the plate using the silicon rubber posts included with the Noctua.
For the plate to the mounting posts I used the rubber grommets used to mount the original fan - it dampens it a litte.
Damping the top cover was a good suggestion by @200man
You lowered the RPM by inserting a resistor. Good idea, that way you also lower the power draw back some.
Where did you get it from? Is it part of the Noctua package?
