Was actually reading about Positive and Negative Air flow case cooling when it occurred to me that you could theoretically match the sound wave with the same noise and eliminate it audibly.
Okay, you're talking about something you don't completely understand there
From your description, you sound like you're trying to have some sort of 'noise cancellation' thing going on. Your thing sounds good on theory, but impossible in practice, as if your fans are the same frequency, BUT just half a wavelength off, you end up DOUBLING the amount of noise produced. Unless you can figure out how to:
a) make your fans go at the exact same frequency; and
b) make them start making noise at the exact same time; and
c) position your fans in the perfect position in comparison to where you're sitting so the sound waves reach your ears at exactly the precise moment for cancellation;
this whole thing just wouldn't work. Given that I can't even figure out a consistent way to drill a hole with a hand drill at a precise point (and we're just talking about visually precise here, which isn't precise at all compared to the measurements involved with sound waves), I'd give that up as impossible.
However, your positive and negative airflow thing is definitely interesting to me. If you've read one of my other threads, I'm building a custom case, and unfortunately for me, there isn't much space to mount fans. My 2-exhaust-fan-0-intake-fan custom case will be an ultimate negative-pressure case (which describes just about all mini-ITX cases out there I've seen). I'm designing specific intake vents for the case in hot-spots within the case, and sealing up all other spots with some foam. I'm praying to all the gods man has ever invented that this will work.....
