About the shroud... was an idea to contain and direct the fan and
convection driven airflow. I imagine it to be a shallow u section, open
at top and bottom, enclosing fan and fins. I think it has potential,
seeing as I want to replace my fan I'll give it a tryout.
Thanks for the replacement fan tip. I can't recall for sure (in a court
of law *S*), but I think there was a resistor directly wired to the
original fan which I removed. But I suppose I'll soon see. The muffin
fan sounded like it was going full speed.
thanks again for the info Mark.
