First thx for your work and advice, I appreciate the time and the effort of silentpcreview to explain as simple as possible the ways for a silent computing.
Second I am surprised that the Fortress 02 is not more silent than the Raven 02.
Ft02 have dampening material all over the the chassis. Is not strange that it have the same sound signature of the raven 02, and that is not a couple of db quieter?.
At same time the temperature of Ft02 should not be higher (again the dampening material)?
Thank for the attention.
The damping material is quite thin. It may soften the high frequency sounds a touch but that's about it -- and there is very little high freq noise in most systems these days -- other than small fast fans which we always avoid. You notice we didn't talk about the damping -- that's because it might as well not be there. This is true in most cases. Damping materials really don't do much once the noise level is down low, and even when there is more noise to be damped, the simple reality of PC cases is that even if the walls are made of concrete, they are full of holes (vents for fans) through which sound can escape.
The only way sound damping material could increase case temperature is if it blocks the vents and/or there is inadequate airflow and a huge amount of damping which could hold the heat. Neither applies in most PC cases, and I've never seen temps rise because of sound damping -- except if the above conditions apply.
Thanks for the answers Mike,
I really thought that the aluminium parts were used to help the heat dispersion and so covering them with foam would reduce the heat exchange. Heheh I am another victim of marketing. They should do it in steel at least would be less pricey, anyway being so huge I doubt people will move it around a lot.
I have another question on the space between the pci/pce slots and the covering grill on the top. Is it possible to use a dvi/analogue converter for monitors?
I ask this because I have still my lovely 22" crt (Lcd are still crap compared to the quality and flexibility of old professional cathode monitors, I know I know Lcd are cutier, lighter and bigger), and I have the feeling that if you put the DVI converter there you can't put back the grill.
I noted now that one of the 180 fans (the one under the HD cage) has not the plastic honey comb cover. If I remember well you found that that cover helped in silencing the fans.
LOL at this point I think is evident that I am disappointed, I hoped that Ft02 would be quieter than Raven 02
