Cancelling Out CPU Fan Noise
Percy_Blakeney writes "After realizing how noisy his computer was, a professor at BYU has created a new CPU fan that uses small microphones and speakers to cancel out its own noise. It isn't perfected yet -- it only nixes the whine, not the whoosh -- but it looks like it could be promising, especially given the professor's background: making jet engines quieter."

yea dude quiet fans firrst post
next to no. fucking engrish paper eating my brain. this is a bad sign.

rattle of a clapped out sad wanker boy racer in the car.
If that's the way a young guy wants his car to sound, then leave him the hell alone. You do not need to describe it as being a 'rattle' from a 'clapped out sad wanker boy racer'.
Does criticising these guys make you feel better about yourself, or the car(s) you own?
Shut the FUCK up.
(No, I don't drive a modified 'riced' car, but am tired of hearing dipshits like you)
You must be new here.
This guys works down the street from SCO. Pretty soon, ever CPU user with a cooling unit will likely get sued for patent infringement!
No, they mesurably change sound slightly (at least the ones I like). I've checked with actualy measuring equipment. It's not much, I'm not sure I could pick it out in a blind A/B test, but it's real. I figure why not? Doesn't hurt anything, and ensures that the sound isn't going to change on me. I use my speakers quite a bit for mixing and mastering, so I need the sound to be consistent.
You'll also notice that your articles are talking about CABLE break in. Yes, that is a crock of shit, as are high end cables. I use normal braided copper wire in nice sheaths. Speakers are a different matter. They are actual moving parts. As such there is a slight difference in stiffness at manufacture than after some work.
I'm not going to run around claiming that all those who have never burned in their speakers are missing out on some awesome experience. Speakers burn them selves in with normal use. It's simply to give them the equivalant of a bit of use to normalize the sound and get past any slight changes that are going to happen.
Well some of the articles talk about cable break-in, but the search brings up several speaker-specific articles (for exmaple, the topic "Speaker burn-in question"). Dick Pierce's comments are particularly insightful.
No, they mesurably change sound slightly (at least the ones I like). I've checked with actualy measuring equipment.By how much? (and measured with what?) Enough that the difference can't be attributed to humidty, temperature and ambient pressure differences? Speaker drivers are generally "burned-in" for several hours at the factory as part of the Q/A checks. Any more is redundant.
completely offtopic, but i have to show how lucky i know i am...
average GPA of incoming freshmen (unweighted) is 3.7.
my gpa? 2.9..... and i got in. could be the 30 ACT, but i'm still a lucky piece of crap.
