Ultra-quiet PC colling; a different approach.

[Theo Hogers]

Hi Rob, Alex and others,

moving the sounds like a good solution I'm gonna try it soon...

There is another appoach,
remember those cabinets where you could put you matrix printer in to muffle
the sound?
The same system works quite good on a computer, I used it on a XT.
Bassicaly it's a box made of MDF with acousic foam on the inside.
Its to big to sit on my desktop but if room is not the problem you might
consider this option..
You don't want to obstruct air flow, air input is best on the lower front
side, output direct behind the fan.
To kill the fan noise, I used the stuf they use as fat filter in kitchen
fans, about 4 layers works fine.
XTs don't produce the amount of heat modern PC do, maybe heat can become a
problem.

Cheers Theo.
