    Is it worth it to buy one of those fanless gfx cards with big heasink, special psu's etc. to avoid the noise caused by the fan motors ?

    Cheers

    No: Buy a Dell.

    If you like your machine - live with the noise.

    Just to clarify, I mean the electromagnetic noise not the one that would be captured by an external microphone. My audio card is internal but has a very high S/N ration (>100db). It's a Phase22 by Terratec. I've checked the AD converter chip and it's the same one they use on the external models.
    The environment in a computer case is said to be full of electromagnetic interferences but I don't have any "hands down" experience on it, hence my question before parting with any money...

    All the fan motors in a PC are brushless. IE, they don't or shouldn't generate any RF or other type of electromagnetic noise. Most of the electromagnetic interference that you encounter in a PC will be from outside sources, florescent lamps, some fan motors, furnace motors, switches, etc.

    You may also get some RF interference from local radio transmitters. RF type interference is more often from poor shielding or poor grounding of your components and cables.

    If you are getting hum in your audio, then poor shielding or grounding would be my guess. Using a different AC outlet may help and using the same outlet for the PC and other connected devices may also. Then there are external AC filters that may help. Checking the quality of your grounds for your AC is also a good idea, from where your power enters the building to the outlets. At your power meter, there should be a grounding stake. Make sure the wire is securely attached. Same with your outlets.

    Shorten your audio cables, use good quality cables.

    And all of this may not help. Some audio cards are more sensitive to noise.

    If you are getting noise or interference, what type is it? If you can describe it better, that would help considerably. A PC isn't normally 'full of electromagnetic interferences' as they generally are well managed if all connections are secure and your components are working properly.

    I guess "Full of electromagnetic interference" then is the marketing hype (which I was believing), that they use to sell us those external models with all sorts of cables and connections in a separate box.
    I'm just making up a small and humble system enouph to record guitar(amp modeler) and drums (external mic) so I haven't tested it yet, was just getting some advice cause I had taken the above for granted.
    Great post by the way, thanks...
