I don't think there is any electronic noise from a computer fan, but, we have only used the roof antenna once since we bought the ES!

As an alternate source of 12V in the Stereo cabinet, I think it would be feasible to find a 120V transformer of a low enough watt/amperage for a muffin fan and pigtail the leads to the muffin fan. The fan I have is rated for 10.2 - 13.8 VDC, 3.84 watts, .32 Amp and moves 85CFM at 3000RPM.
