Here is my two pennies worth on the subject.

I did buy a single (just push) Noctua NF-F12 iPPC-3000 to see just how well it would perform compared to the original jet engine.
Even at full speed (2780 rpm) it could not cool the miner properly at 26 C room temperature. It would keep the miner at a constant of
63 degrees Celsius. About the same performance as the original at 35% fan speed. But the noise of the original at 35% is lower (and somewhat duller)
than the noise Noctua NF-F12 iPPC-3000 produces at full speed. Based on this experience alone, I would be hesitant to call the Noctua NF-F12 iPPC-3000
an upgrade.

Two of them should be an upgrade, personally i want to try the silverstone 140m FHP-141. IT has much more CFM and the noise is better. It cost less. I don't see an upside to the Noctua.
