Ok, Machina, that is a temporary solution, but unless you sit your iXPS on a box fan, I don't think turning off all fans for extended periods of time is a good thing.

He had his laptop pluged into a surge protecter the entire time. He later went ahead and plugged his laptop into a three prong to two prong adapter plug. After that he said the humming was gone. Could it be that the ground on the three prong was making the noise? I havent tried this myself but I figured I would passs it on. He is emailing Dell to see if this is a fix. Let me know what you all come up with.

1. Plug some headphones into the headphone jack and put them on.
2. Turn the volume all the way down.
3. Go into Ik8fanGUI
4. Enable Direct Fan Control and set your fan speed to "high".
5. Apply the fan speed change.
6. Listen for any change in sound in the headphones between the fan going "high" speed and "off".
If someone can tell me whether they hear hum with the fan on "high" or "slow" but not when "off", that would help me a great deal in determining whether my computer's sound unit is defective and picking up interference from the fan.
