I just bought a fan at Radio Shack to mount on top of my monitor to draw
air through and keep the poor thing a bit cooler.  The salesman said it
would be appropriate for that, but in fact it causes a definite shimmer
or wobble on the screen when it's on.  This is understandable, of course,
since there IS, after all, a magnetic motor in the fan.

My question is, what could I do to shield the monitor from the magnetic
field and still have the cooling work?  Would a metal grille under the
fan help?  Should I put a cylinder between the monitor and the fan, 
holding the fan up a few inches?

The fan is a 120VAC fan, rotating at 3100 rpm and with a 32 cubic ft/min
airflow.  The monitor is an Apple hi-res RGB.  The fan actually does a
VERY good job of keeping the monitor cool.

If I don't manage to solve this problem directly, I may just let the fan
sit there, and turn it on only when I step away from the computer.  Could
this fan damage the monitor in any way?

How is Apple's internal Mac II fan shielded?
