How to make conceal the noise ventilator of a HD 192?

Post by Bluenoiz »

Hi all, someone tried? Can I remove it? I wish to bore holes in the cap, up and down for a circulation of air. Is it a good :idea: or I must forget it?
Thanks in advance, Olivier

With some of the heat issues mentioned here, I personally would recommend against it, unless you were absolutely certain that you had provided it with an equivalent means of cooling (ideally even a better one).

The improvised cooling idea isn't impossible, however. You may flip through some of the posts here to see what was recommended for that. It often comes down to:

* mechanical "decoupling" of the fan from resonant metal,etc.

* damping of resonant materials (don't impede the airflow/cooling though)

* a quieter or slower cooling fan

* a different means of getting air in, or out of the case (turbulence from sharp edges or turns and small holes, can add some noise)

This is general cooling advice. I really don't know the 192, but some of it can apply to lots of devices.

Also, not sure how many separate heat generating components are involved, but there are probably even specific areas or parts which might benefit from more airflow or passive cooling (heatsinks,etc.). Your idea of bringing air upward and letting the heat rise up and out of the unit, sounds good, as long as it has a clear path, without being likely to "bypass" the right areas.

Good luck and be careful!

Ok, thanks!

I have the impression that Motu added the ventilator at the last time, with a minimum optimization...
Fresh air intake, up on left side, and extraction cooling fan on the other side...

I just fixed three HD 192s by removing the fans then cutting squares of
1/2" foam rubber that are big enough to fit the fan into after you cut out the inside of the square. Make the cut slightly smaller than the fan so that it grips the fan well. I used tacky glue to stick the foam to the inside of the HD 192 side panel centering it around the exhaust port. Mount the fan inside the foam square and reconnect. Be careful of the capacitors which make it
difficult to remove the lower screws when first taking out the fan. When you're finished, the fan is only touching the foam and the units are nice and
quiet. Also, be careful when tightening the xlr screws as the connectors are nylon and the screws will strip it fairly easily. This mod would work for 1296s as well.

Yes, very good :idea:!
thanks!
I try it!
