Can you overcool PS fluid?

^but at what temp?

I'm seeing online that the temp can get to 250 degrees, so what's the sweet spot?

Not exactly the same fluid but here's a chart I found for temperature vs. viscosity. I would think from an engineering standpoint as long as you stay on the lower, flatter part of the curve you'd be fine.

A temp vs viscosity graph should tell you what you need to know. I assume that it will be close (enough) to what is used for engine oil but don't know for sure. I'd shoot for 180-220 F operating temp unless I got a differing opinion from someone that knows what they are talking about.

Edit: I see gomer_110 posted a graph. Nice find.
