fyo, Re: sound levels I actually borrowed the sound meter but it is only $35 from Radio Shack (http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&category%5Fname=CTLG%5F002%5F003%5F018%5F000&product%5Fid=33%2D2050). I am planning to purchase a much more sensitive and accurate sound meter (30-130 dB, +/-1%, about $180). Had also considered a nice anemometer (borrowed one didn't like the flow rates from high speed fans) but decided I don't really care about cfm, just the results: temperature and noise. In your case, it sounds like a second, slow case fan and slow PSU fan (with full open discharges w/grills) should do it. I think the entrance/discharge air flow noise is far more important than the fan noise itself - but there are limits to how I will modify a PSU! -PT ps: I will be following up that article in the next couple of weeks and see if I can drop another 5 dB and 4C.
