    is there any kind if rule of thumb on sizing heat sinks and what the acceptable operating temps would be?

    For operating temps it's best to keep the heatsink under 100F or so. A little higher is okay but you certainly don't want to be anything higher than about 120F.

    For sizing heatsinks it really depends on the height above water and the optics, so it's hard to say for sure. It also depends on what kind of PAR levels the tank requires so there's no definite rule for that.
