I was thinking about applying Noise Canceling tech to my pc. Ive always said I want my pc quiter on then off, and this seems like the only way .
So lets start a discussion about difrent Negative noise techs.
Me and my father think fundamental is the anti-phase of a single tone sorce. Using a mic at desired usage position
Am I insane, can you hear the water heater request water or hear your lcd turn on and off?

Well... Noice cancelling is a good tech, but I think that it dosen't work with pc:s very well. Because it's normally reduces noice to one direction and ad it to another. I suggest that you build a air/water cooled system in a insulated cabin with noise traps in air canals.
I have an watercooled system and an only fan is in psu. Adda 120mm in a 5 volt and only thing I can hear is an really silen humm from water pump and a little whine from my Samsung 950b TFT

This has been discussed many times already:

Conclusion:
Like pollution, it is a lot easier to stop it being produced in the first place than to clean it up once it is in the environment.

Conclusion:
@NeilBlanchard:The only thing that can work along these lines is a headphone type setup (and the Bose units used to cost a lot less, BTW -- like $70-80 IIRC). Because in order the cancel a noise, the "antidote" MUST be exactly 180 degrees out of phase, and since the sources of the various noises in a computer case -- are in various places, there is no practical way that a single device could cancel all the noise!
And as you move around, your ears change the distance from those noise sources -- and from the cancelation device, so again, there is no practical way that a cancelation device can work EXCEPT if it is attached to your head!
Noise from a computer is not a pure tone, it is broadband.Me and my father think fundamental is the anti-phase of a single tone sorce.
