Excellent test just like your sandwich test (looking forward to the continuation of the sandwich testing). I'm curious how this stuff would look with dye, would the dye even take to the nanofluid?

If you still have the loop filled, take the fan off the single 120 radiator and just have airflow coming from a distance from an 80mm or weak 120mm fan, I'm just curious what the result would be considering the results from the weakest cooled-radiator. Perhaps (I know I'm reaching) allowing the removal of radiator fans to be replaced by one or two case fans blowing very little air over the radiators. (forgive me for even suggesting you to take the chance with your Q6600, nothing personal against your hardware, I'm just curious)
