ventilation fan vibration isolation help needed

I will be putting two exhaust and one injection fan in my cabinet to properly move air. Two will be mounted horizontally and one veritically. The trick is that I work so hard to get the cabinet isolated from vibrations that by adding a fan, I'm added micro vibs to the cabinet. The fans are 4" radio shack fans running at 6 volts instead of 12volts in order to slow them down and reduce noise yet still move air. I was planning on using placing a sorbothane grammet (if I can find some) around the screw that is screwed into the cabinet and it would hold the fan about 2mm off the cabinet. Any other suggestions. I want to keept it simple but yet very effective. Thanks Troy

Look for Nexus fans.

The quietest mounts I have used on my computer are these fan mounts:

I think they are available at many online computer stores, as well as McMaster-Carr.

When I added a fan in my old cabinet I went through a bunch of different ideas. The best by far was to hang the fan from the shelf above with cord, so that it gently blows over the top of the ewuipment. Then get a dimmer switch and connect it to the fans so you can turn them down and reduce the noise factor from them.

You really don't need much air movement to cool things down. A little goes a long way, as long as there is some ventilation in the cabinet. I used to crack the front door open a wee bit when playing music.

Enjoy,
Bob
