I am building my first pc and am using the Cooler Master HAF 922. I bought this case based on its roominess and cooling ability. However I understand that it can be quite loud running under stress. In order to quiet some of the noise I am contemplating using a noise dampening foam like
Most of the foam products produce mixed results. In addition, the 922 like the 932 has a lot of ventilation (openings) so there aren't any really large areas where the foam could could be applied.
Some gamers install a fan control in a front bay which lets them manually adjust fan speed. During ordinary use they will reduce the speed of the fan to lower the noise level. They'll raise the fan speed during intense gaming sessions or other sctivities that would result in higher temperatures.
+1 for what the other skeleton guy said. The HAF is very "venty" is a big advantage for cooling, though it does give noise lotsa places to get out and whichleaves little room for application of any sound deadening material. . Cases which emphasize noise control have to take other steps to provide cooling....See Antec P183 / P193 for example.
