^^ Well, it was a total letdown. I was happy that it was on my test rig first. I was just trying to see how big of a difference it would make compared to the original cooler. Truthfully, I was not that impressed in the drop. Perhaps the pump was truly screwed from the get go and Green Rain was going spray whatever computer it was put into. I know that Water is the best and more stable... But seriously, Passive is truly working for me. Does anyone else here run passive. Have you found it's upper limit?
