So it is confirmed bad.
No I just need to decide if I should return the URO fan clutch I just bought and get a BEHR or keep the URO.

The fan clutch doesn't really tighten until 100C. My experience is that it acts like and on/off switch rather than tightening slowly as the temp rises.
Let it idle and before temp reaches 100C rev the engine to about 2000-2500 and "feel" the air flow and listen for fan roar. Then let it continue to idle until it's over 100C, but less than 105 when the electric fan engages. You should feel more air flow at 2000-2500 and hear plenty of fan roar.
Shut off the engine and check how much force it takes to turn the fan by hand. It should be much greater than when cold.
Failure of either of the above indicates an inoperative fan clutch.
