Blokhead Fan Duct Upgrade for Ender 3

Install & Test of the Blokhead fan duct upgrade on Ender 3 Pro.
I take a look at the new Blokhead fan duct upgrade for 3D printers. The Blokhead is the new fan duct upgrade from Petsfang. It is the successor of the well known Bullseye fan duct upgrade.
After installing the Blokhead on my Ender 3 Pro, I test the air flow and the noise level using a water test.
Then I compare the print quality between the Blokhead, the Ender 3 pro stock cooling system and a benchmark (fan off).
