Thinking of going e-fan

MoTeC with a CAN to the AIM dash, so I read it where the ECU sees it, right behind the Tstat at the hottest point.

It's fine, there's nothing wrong with that.... most modern cars run at that temp anyway

Depends, what are your oil temps?

Custom built AL

SS retains heat more than the AL will shed it... you're basically retaining the heat with that piece of SS. Also.... the fan needs to be spaced off the radiator at least an inch. This will pull more air through a larger area

Mistake number 1 is have a switch for a fan... it should be automated

I'm making a lot more HP and don't have cooling issues..... my temps on a 104* track day never saw above 185* coolant 200ish Oil. How well ducted is your VMIC setup?
