I'll be curious to know how much of a difference the city water fan
makes. I know a list member (Mark Drillock?) has installed one and has
seen improvements.

The sensor on the aluminum cooling unit slides in a groove on the
back. There is a piece of rubber (silicone?) that holds it in the
correct position. I *think* this sensor is supposed to contact the
aluminum.

Pic of cold tube and cooling unit. Not easy to see, but it shows the groove.

Check out Roger Sislers page. Lots of pics and info. IIRC, there is an
explanation of the part you're curious about.
