Reservoirs vs T-lines in Flow Rate = Insignificant

[ranker]

If possible though for absolute best efficiency, putting that probe on the 90 side of that T so flow passes straight through would be even better.

I would if I could, but I can't find any other way to connect my RD-30 to my radiator AND include a G1/4 water temp probe at the same time. My case is so cramped and tight it's the only solution I can come up with. It's why I'm asking for the theoretical impact now to see if its even worth using the temp probe.
