Actually, there are five on the UrQ. You're forgetting the fan low temp
thermo switch on the bottom of the radiator, and the fan high temp thermo
switch plummed into drain of the coolant overflow tank. How do I know
this? I just recently had to figure it all out so I could put the head
back on install the killer humongo fan out of the 5000. I don't think
there's much chance she'll overheat anymore :-).
