so i found these on ebay,
http://www.ebay.com....872.m2749.l2649
and as best i can tell
are an open circuit GROUND connection..
till water temp reaches (185 f) 85 Celsius, then "closes"
and
"opens"/ turns off when temp falls back down to (175 F) 80 C
so i was ASSUMING i could run a constant active to fan,
and the ground directly from the temperature "switch" (sensor)
nice and easy process and would work perfectly, i think.
and for just $5 too.

so then why all this setup/hassle KITS??

anyone know the pros and cons of either choice?
thoughts would be much appreciated
