I would like to build a special housing unit for my HTPC that will block out a good deal of fan noise yet still keep it cool. I was thinking of using some 80mm Panaflo 12L fans externally for the exhaust and intake of the house. In case you don't know, they are 21db loud and are quieter than the L1A fans. These will be used in addition to my 120mm fan and two 80mm exhaust fans in my pc case. Check out my design idea HERE at the top thumbnail. The last time I posted this I got nothing but suggestions on how to quiet my PC without having to build a separate enclosure around it but I have scraps of MDF, extra polybatting, and time. If you think you thought of a way to quiet my PC I probably have already tried it without success, I'm running an overclocked (GPU and CPU) system seen HERE. Any comments on how much this will quiet the PC or alterations of the design welcome as I labeled/colored the pic for identification. Some numbers I'm dealing with: Radio Shack SPL meter C weighted Slow response: 56db 1 foot from front of case 60db 1 foot from side of case Add 3 decibels to those numbers when I turn up the 120mm intake fan to full RPM. Sadly enough, these levels arn't exactly pleasant for me but I've heard far worse.
