agreed, inline filters are good suppressors for the pwm driving the fan,
but shouldnt they be placed on the supply lines going to the PWM circuit
rather than between the fan-pwm? the entire wire length is probably
radiating all sorts of splatter emf everywhere. shortened and even shielded
may help also.

or both places?

if possible, find some tech guy to alter the PWM circuit to prevent such
drastic sharp rise times in the switch circuitry itself?

Please don't top post.

Even Google Groups advises against it.

From:

http://groups.google.com/support/bin/answer.py?answer=12348&topic=250

"Summarize what you're following up.

When you click "Reply" under "show options" to follow up an existing
article, Google Groups includes the full article in quotes, with the
cursor at the top of the article. Tempting though it is to just
start
typing your message, please STOP and do two things first.
Look at the quoted text and remove parts that are irrelevant.
Then, go to the BOTTOM of the article and start typing there.
Doing this makes it much easier for your readers to get through your
post. They'll have a reminder of the relevant text before your
comment, but won't have to re-read the entire article.
And if your reply appears on a site before the original article
does,
they'll get the gist of what you're talking about."
