It seems that density is very closely tied to viscousity also, I'd be interested in a liquid that is more dense than another but yet less viscous.

For the same flow rate, yes, but you won't achieve the same flow rate with the same pump, wether its because of the density, or the viscosity. although, I remember reading somewhere though, that most pumps reach the same flow rate, regardless of fluid density, but since a heavier fluid will probably be thicker too, we just can't picture it.
I need a viscosity table! I believe that mercury, although lots denser, might have a similar viscosity as water. Does anyone know?
(It doesn't mean that mercury is a better coolant, we can look into that some other time!)
