LOL, I understand the tired comment completely

There is one other important piece of info missing (or maybe I just missed it). What is the water flow rate through the system? And when you make your next test run, could you vary it at all? Wouldn't have to be a lot of increments, maybe just 2 or 3, say around 1gpm, 1.5gpm, and "give me all she's got Scotty" or if just two, then around 1gpm and 2gpm. If nothing else you could put a ballcock valve inline to vary the flow on the cheap.

Also at a lower flow rate (maybe much lower since we don't know your current flow rate, but I would guess in the 2gpm range or more with your setup), we should be able to see a delta in the outlet water temps for the different blocks which would provide good info on the heat transfer capabilities of the blocks. The idea here being not testing how well they cool with high flow rate s, but intentionally lowering the flow rate to get better insight into the heat transfer capability of the blocks themselves.

Of course, then it would most likely be best to put a temp probe on the inlet side of the block so we could see the DeltaT across the block

(just suggestions in an effort to get the best data, ignore it if it gets to be too much, LOL)
